Mr Zanetti tests Invictus Speaker Reference

After a too long period of silence, the vicissitudes of our most exuberant client are back: Mr. Zanetti. We left him in the middle of a scientific and technical test with protagonists, clearly, our products, in particular those of the Dedalus and Invictus series. Today we are back on the digital pages of our site putting the new Invictus Speaker Reference to the test. Enjoy reading!

The reconquest of Everest

So, like all stories, this one has a beginning. Mr Sergio had been mulling something over since last winter: he had seen a particular insulating polymer. That's what he told us during one of our visits, when my colleague Alessandro and I went through the various cable spools in the warehouse. Mr. Sergio revealed us that he would like to improve his cable Speaker top (the blue one) implementing it, among other things, with this particular insulating polymer. That's all he said!

Months went by and around November we went back to see Mr Sergio. I noticed something different about the environment: there were more people. Yes, since quality pays, our entrepreneur had had to hire two more people, which is very important in these times of epochal crisis. He had prepared a prototype of this new cable Speaker and finished it himself. At first sight it looked the same as the previous one; he would have liked to have it listened to someone with a system of a certain level. When he heard this, my colleague Alessandro immediately took possession of the prototype, enthusiastically stating that he would have tested it himself.

After a few days, Alessandro told Mr Sergio that the cable was exceptionally good and superior to the previous one. I had to wait about a month before production started; it seems that this cable is not too easy to build. I was curious to try it out as I have recently upgraded my system. I currently have a brand new Yamaha A-S3200 integrated amp (25 kgs of top technology) and a Technics "Grand Class" SL-G700 all-in-one player.

I've appreciated the Technics player's construction: it uses two AK4497EQ multiple converters (one for each channel) by the Japanese Asahi Kasei. These are converters that are also used in equipment costing three times as much and more!

Yamaha A-S3200 Zanetti

So I get this new cable and I start listening. But first I look at the specifications. The data has improved slightly: internal wire count has increased from 970 to 1038, capacitance and resistance have decreased. Outer diameter increased by 2mm, conductor cross-section (this is where it gets interesting) increased by 0.5mm. "Um," the outer shielding is also improved. It's now 7N copper. "Ah!", there's also a double dielectric. We'll see. Looking at the new features, it wouldn't seem so different, but Alessandro was highly impressed.

I take out all my reference SACDs and put aside my "liquid music" files. First of all I have to say that due to an irrepressible audiophile infatuation I bought from Mr Sergio and therefore I own: three Invictus power cables and two Invictus balanced signal cables, which have been used to carry out the listening test of this Invictus Speaker Reference.

Well, I start with an "old" Telarc SACD from 1999. It istitled: Stir It Up, the music is by Bob Marley and it is played by a small band with Monty Alexander. The rhythm is fast and continuous, the band doesn't miss a beat. Impossible to fall asleep, the record is very enjoyable. The sound message is full and powerful but there is something that amazes me. I've never heard the guitar chords so clearly: when Steve Turre's trombone comes in I jump out of my chair! "Uhm, maybe I'm hungry, I'd better pick this up later.

Invictus Speaker Reference

I try with another SACD: a Telarc from 2004. Thetitle is tremendously challenging: The Best of Play Bach. This phenomenon (really!) of Jacques Loussier performs works by J. S. Bach on the piano with bass and drums. The impossible has succeeded! The performance is transcendental in its Pastoral in C Minor. The bass is killer and grabs me in the stomach, leaving me dumbfounded! Something is not right! Now I call Alessandro and I go to listen at his house. I arrive and I say: "Did you hear that?". Alessandro doesn't answer, he puts a black disk on the record player that improperly is called "vinyl", but it should be called "polyvinyl chloride". Let's overlook it. The cartridge is a MC (moving coil), with a higher sensitivity than a MM (moving magnet).

He turns up the volume on his McIntosh to maximum: "Unbelievable! No noise coming out of the speakers! But what the hell has Sergio done?". "I don't know" answers Alessandro and continues: "He has surely done some devilry". I go back home a bit dazed, let's try again tomorrow, that's enough for today!

Today I want to start with ninety pieces. I choose a piece for piano solo, in DSD256, the pianist is Japanese: Ikumi Ogasawara, the title of the "record" is Tears of Joy. I choose the piece Whale Lullaby*. The song is poignant, of a unique beauty. The surprise is that I am not in the front row of the imaginary theatre, but I am in the pianist's place! I am surrounded and immersed in the notes! Sensation never experienced.

I continue with more pieces for harpsichord solo and virginal entitled: Parthenia, performer Catalina Vicens. I've heard a few baroque music concerts, as they say, live, but here we're off the charts! It seems, excuse the hyperbole, that the god Aeolus blows the notes directly on my body. Unbelievable stuff! I will buy the cable for sure! I go on with the listening anyway. I try another DSD256. Paganini: O mamma, mamma dear. The violinist who now plays the viola drives me crazy with her reckless phrasings! Even here the viola comes up to your nose.

Well, now I'm trying to think what artifice will be resorted to by Mr. Sergio. More than one for sure. The irrefutable fact is that this cable reduces, according to my ear, the electronic noise by about 20 dB. A remarkable result, maybe more than remarkable. I believe, always on the basis of my rather long experience, that such a cable, if sold by very famous American companies, would not cost less than 7 or 8.000 European EURUCCI. Meditate, people, meditate!

Greetings, L. R. Zanetti.

Where to start when changing Hi-Fi cables

The idea of rewiring one's Hi-Fi system may come from many quarters. We may be newbies who are indulging in high fidelity music for the first time. In this case it would be more correct to talk about wiring, then, rather than rewiring. We can be old fashioned audiophiles who, after having put aside their passion for some time, are now recovering it and want to get back to working on their electronics. We can also be enthusiasts who have decided to finally offer an adequate support to the components of their own system, going beyond the cables we find in the big organized distribution. Without exaggerating; the key word, as we've already had occasion to reiterateis "balance". But the question we want to answer today is: where to start when changing Hi-Fi cables?

Which Hi-Fi cable should I change first?

The following indications about where to start changing Hi-Fi cables apply as long as the system has similar level of cabling in each connection. The situation is different if you have already bought some good quality cables. In this case, in fact, the priority of intervention would go without doubt on those that are the weak points, if it is true that it is the weakest link of a chain to measure its strength. Having said that, the first Hi-Fi cable to be replaced ideally does not exist, in the sense that the best solution would be to change them all at the same time. This would also guarantee the continuity of technical and constructive philosophy in every connection between each electronic. Easier said than done, though. For budget reasons, or even for the choice of changing one piece at a time to see the differences, this is, most of the time, not possible.

Chain

So, coming to compromises, we'll have to take the bull by the horns and decide which cable to start from to rewire our Hi-Fi system. Obviously, we are aware that it is always a starting point and we must never be satisfied with a single improvement. Let's imagine that we have to resurface ten kilometres of a road. To be honest, it won't make much difference if we decide to resurface the route starting from the end, or if we choose to resurface the fourth kilometre first, then the seventh, passing through the first and continuing randomly. It may take us a little longer, but the end result will be essentially the same. For a question of directionality of the signal, as well as, maybe, of mental order, it would be anyway preferable to start "from the beginning". The first Hi-Fi cable that we suggest to change, in order of importance, is just the signal one. After all, we're talking about the cable that transfers the signal from the source to the amplifier in most systems, so of central importance.

dedalus signal

How to continue wiring your Hi-Fi system

The second step we recommend is the replacement cable Speaker. All connections are important, especially in order not to create bottlenecks in what is the journey from the power socket to the transformation into sound perceived by the ear. But we feel like saying that, maybe, some cables have a more dominant role. We have written it for the signal cable, now we repeat it for the one Speaker . This is the cable that carries the now amplified signal to the components that will carry it out, and which are responsible for its diffusion. It is the last step before reaching our ears.

Changing the power cables

Now we come to the last of the main cables (signal, power, power supply) that we recommend you change: power cables. Maybe because these aren't important? Absolutely not. We indicate them as those on the last step of the podium in the wiring of the Hi-Fi system for two reasons: because they are so much respect and because they do not intervene directly on the signal, but on the power supply of the electronics. The vast majority of Hi-Fi systems have a signal cable, a Speaker cable and at least a couple of power cables. The higher you go in the hi-fi chain, the more electronics with separate functions in the chain. This means that the number of mains cords we will need will increase. Not exactly the best place to start when considering where to start when changing mains cables. In this respect, the first mains cable we would recommend changing is the power amp cable Speaker , whether integrated or not. Nothing will be as good as trying empirical tests, however: "run" the power cable you have purchased and see for yourself where the benefits will be most obvious.

Conclusion and important clarifications

The high fidelity is a passion that never bores, among other reasons, for the infinite possibilities. In terms of electronics, but also in terms of system configuration, for example. We have already faced the talk about the number of variables in this sense. Then the personal tastes, the songs... you name it. Even when we talk about where to start wiring the Hi-Fi system, the discussion does not end with this article. Some customers have told us that they have rewired their electric system, as well as the cables inside. chestswith surprising results. Today's content is an excellent starting point that will satisfy the request of all those who have a valid Hi-Fi system, even if without esoteric pretensions. So, we just have to suggest you to have a look at our catalogue, to understand where to start filing up your connections!

How to choose the best Hi-Fi cable: the series Ricable

The functionality of a cable, even in a particular context like Hi-Fi, is under everyone's eyes. A cable connects the electronics to each other, and does it better or worse according to the quality of the materials, the construction and many other aspects. Whether it is a power cable, Speaker or a signal cable, with a good support that connects them, the electronics in our Hi-Fi system will work better than with a poor or standard cable. A clarification that we have made in more than one of our articles(repetita iuvant): a Hi-Fi cable will never improve the sound of your system. All it will do is deteriorate it as little as possible - which is no small thing, in fact, so much so that it is important to choose the best Hi-Fi cable for your electronic specifications. The cables Ricable, from this point of view, are born to give back to the listener the maximum possible neutrality.

Invictus Speaker Hi-Fi power cable

Choosing the best Hi-Fi cable

Imagine having spent an arm and a leg to get a top-notch amplifier and acoustic speakers, only to have a connection between them compromise the sound quality. It would have been better to have thirty-one instead of thirty, wouldn't it? An audiophile knows very well that the choice of an electronic is not only the result of an economic effort, but also of time, if we consider how long it takes to document and carry out the relative tests. So here is a characteristic that is often underestimated: the balance.

Let's be clear: the day is yet to come when we will recommend one of our top cables to an audiophile who owns a Hi-Fi system that is within the norm. An exceptional cable in a discreet system would not produce any damage, of course; but the same system would probably not be so detecting to make you notice differences with a less performing support, even if good. The opposite, instead, could be much more harmful - and this is what we were saying. A poor cable in a respectable hi-fi system will demolish all the effort that has gone into setting it up.

Keyword: balance. How much to spend on Hi-Fi cables?

The balance, therefore, plays a key role. Maybe even more than the amount spent to assemble our whole Hi-Fi system, between cables and electronics. Imagine a racing car with a superb engine and an absolutely not very aerodynamic chassis. Or, still on the High Fidelity theme, a system with a fine amplifier and poor quality loudspeakers. A lot of effort for nothing.

When it comes to Hi-Fi cables, it's the same story. It is not optimal to have good cables Speaker and bad interconnects, for example, just as it is important that the value of the system goes hand in hand with the value of the cables used for it. This is an unwritten rule and therefore should be taken with a grain of salt, but a good cost ratio between cables and electronics should be 10-15% of the list price. For example: a 1000 euro amplifier should have cables worth 100-150 euro. We would like to point out once again that the list price should be taken as a reference, in the sense that if we go to the second-hand market and buy an amplifier at 1.000 euro whose original value was 5,000 euros.The cost of the cables will still be 500-750 euro.

Four series of Hi-Fi cables, for every wallet

Taking into account all these considerations, the production of cables Ricable is divided into four different series, so as to meet any requirement both qualitative and economic. The four series of Hi-Fi cables Ricable, except for the HDMI cables, are the following:

  • Primus for Entry Level systems (all Hi-Fi equipment should have at least one Primus wiring harness)
  • Magnus for high-end Hi-Fi systems
  • Dedalus for Hi-End systems
  • Invictus for high level Hi-End systems

Let us repeat here something that has already been said: it's not a bad thing to wire your electronics with a higher level of cable, because some variables are not calculable with numbers, but it could be that with a lower level of product you get the same result, because the electronics themselves, in that case, more than that cannot reveal.

Hi-Fi cable balance and synergy

A certain balance must be preserved not only in the relationship between cables and electronics, but also between Hi-Fi cables themselves. The first thing we would recommend is a levelling of the cabling. Rather than having a very good interconnect and a poor one Speaker , it is better to have both cables of average quality. The best thing would be to have a wiring as uniform as possible, with the same series and brand for all connections. You have to start somewhere, so to help you choose the best Hi-Fi cable, take a look at our full range at Ricable.

Measure Length

The length of Hi-Fi cables Speaker

What should be the length of Hi-Fi cables Speaker ? Quite simply: the length you need. Before making a purchase in this sense, therefore, measure with a string or a wire what is your real need in terms of length of the speaker cable. Thanks to the fact that we produce our cables by hand and in Italy, we can follow your directions to the centimeter. If you buy one that is too long, it will look unsightly and, even worse, it will roll up, and if it is too short, you will have to buy another one. Or you may have to change the positioning of your electronics, perhaps optimised during countless tests. There are a few pointers to follow and a few things to know before making any decisions.

The cables Speaker in the Hi-Fi system

The premise of any discussion of cable length Speaker in Hi-Fi is that it is often not just a matter of aesthetics or the individual cable. Every system is composed by a series of elements, more or less numerous, that are called to play a team game. On one side there are the electronics, which emit magnetic fields, noise and vibrations, on the other side there are the cables, carriers of disturbances in case they are not well shielded. Most of the time, electronics and cables are also located in rather small spaces.

dedalus speaker power cable hi-fi

This synergy leads yes to the sound that nourishes our passion for music and high fidelity, but at the same time has contraindications to be monitored: interference. A well shielded quality cable, such as those Ricable, not only blocks interference coming from outside, but does the same with those coming from inside. So as not to affect "teammates" negatively. Some audiophiles argue that the benefits of not having the electronics too close to the speakers will always outweigh the disadvantages of having very long Speaker cables, for example. Having said that, when planning the set-up of your Hi-Fi system, it is good to keep in mind that the Speaker cables should not run parallel to others, especially the power cables. If we really have to cross them, it would be the case of making them pass perpendicularly. Having a custom-made cable, in this sense, can make our life easier.

But let's get down to business. The greater the length, the greater the the resistance. Based on this unquestionable electronics assumption, we deduce that the shorter a cable is, the better. Always. This is the one that is not subject to objection in an academic context. But coming to the real world, we can estimate that before the length of a cable worsens (sensitively to the human ear) the sound, we need to reach a length of 15 m. Often, therefore, there are no problems. It must be said, however, that in this case also the quality of the overall system comes into play. A very high level Hi-Fi system, extremely revealing, could be affected by the cable length even at shorter distances; an entry level system, instead, will have the "advantage" - very much in quotes - of being less subject to this kind of variations.

Invictus Speaker Hi-Fi power cable

Different lengths of Hi-Fi cables Speaker

The point about the length of Hi-Fi cables applied to Speaker cables is interesting for another reason. Speaker cables have the distinction of starting out, except bi-ampingfrom the same device, and then terminate metres apart when the speaker cables are connected to the respective speakers. Usually, and this is the best solution, the length of the cables going to the two speakers is identical. It happens, however, that some audiophiles, for needs related to to the listening environmenthave to arrange their speakers asymmetrically.

Various tests have shown that, in reality, a maximum difference of 40% between one cable Speaker and another does not make any tangible difference to our hearing. A 10 m cable and a 7 m cable are fine, for example; so is a 6 m cable and a 4 m cable. Beyond that, speakers begin to sound different in a noticeable way. But we must go back to what we said before: the more revealing your Hi-Fi system is, the more it will present this problem in a tangible way, even with a small difference compared to the 40% mentioned before.

Anexception to this is some amplifiers that use the speaker cable as part of the circuit; in this case, the cable lengths should always be the same. In this case, the cable lengths should always be the same. Ultimately, if you want to use different cable lengths, it is always best to seek additional advice from the manufacturer of the electronics. One last consideration when it comes to Home Cinema. Speakers designed for this purpose are less likely to sound different when the cables Speaker are of two different lengths.

Conclusions

Coming to the conclusion. The longer the cable, the more the quality of the cable matters. In particular, the longer the length of the Hi-Fi cable, the more the cross-section of the cable itself should be taken into account, as it will become more and more important in not deteriorating the sound. Ricable stands out for its handmade production; as we make our Hi-Fi cables by hand, we can make them exactly to the length you expect. All you have to do is fill in the form below.

hifi jumpers how to connect them

How to connect jumpers and speaker cables

When we buy a loudspeaker on its back we will have, in most cases, four terminals, in pairs of two, to which we connect our speaker cable, supported by standard jumpers. But how to connect jumpers and speaker cables?

And what are the double binding posts for? To connect our speaker in bi-amplification or bi-wiring.

These alternative modes of connection, almost always for the use of a small circle of enthusiasts, if not used, require that the HF (high frequency) and LF (low frequency) terminals remain jumpered together. The aim is to make the crossover work in unison.

Why is it that loudspeaker manufacturers, given the scarce use of bi-amping/bi-wiring, produce speakers with double connections? Well, it's difficult to give a precise answer, but one can speculate that it is to offer a more versatile and complete product. Or maybe it's because they are "more showy" and attract more attention from buyers. Certainly, they are present on almost all the speakers and, consequently, they have to be understood and managed properly, to avoid that a possible advantage becomes a disadvantage.

Immediately after having made the purchase of our new speakers, we will put to assemble them and we will be caught by a doubt. Should the speaker cable from the amplifier to the speakers be connected to the bottom pair or the top pair? That is, to the input intended for bass or high frequencies? And above all, will the jumpers supplied by the manufacturer of the speakers be adequate for the task they have to perform or will they ruin our efforts to improve the quality of the audio emitted by the system?

How to connect jumpers. Up or down?

The fundamental importance of jumpers arises from the fact that, over time, loudspeaker manufacturers have decided to make loudspeakers with two pairs of connectors and, therefore, a split crossover. The jumper is necessary to carry the signal at both high and low frequencies. But, in mono-wiring, where is it best to connect your speaker cable? Below or above? This is a question that many people ask themselves and to which we will try to give an answer.

Somebody says that the cable coming from the amplifier should reach the tweeter (or better mid-high) binding posts and not the bass one, leaving to the "chunks" or jumpers the task of bringing the signal to the woofer binding posts. High frequencies are the most delicate and sensitive portion of the audio spectrum, also because of the low voltages involved. According to these opinions, for this reason it is better that the signal from the amplifier reaches the tweeter binding posts without any other pieces of cable or metal bars in between (in simple words: contact resistance is minimized).

hifi jumpers how to connect them

Others, instead, believe it is better to do the opposite, that is to privilege the woofer, the component that requires more power. In reality the differences are minimal, and only rarely does anything really change. What we suggest is first of all to make sure that the jumper doesn't act as a bottleneck in your system (see below how) and then make some attempts according to your ear and your system to understand if something changes.

There is no such thing as better quality than what we like best, even according to our own suggestions or habits. You can also refer to the instructions that accompany the product. It is true that it is about ten centimetres of cable and, unless the quality is particularly low, the problem does not arise. If it weren't that, sometimes, the standard jumpers are actually of very poor quality: a strip of brass.

How to understand if the jumpers are good and up to our system

As far as jumpers are concerned, the only way to check their goodness is to try to move the speaker cables from the bottom to the top terminals, and vice versa, but there are many different deductions that we could draw. So, let's make all the possible hypotheses and draw all the imaginable conclusions about how to connect jumpers and speaker cables. Here is the list of possibilities, presented in a schematic but exhaustive way:

  • move the position of the jumpers; if the sound changes, the jumpers are probably acting as a bottleneck and we recommend changing them for optimal performance;
  • If the sound doesn't change, maybe the jumpers do an excellent job and are adequate for the system.

Caution, though. In case the sound does not change, the following aspects should also be considered:

  • If the sound doesn't change, it may be that the speaker cables are so poor that they can't convey enough detail for us to hear differences;
  • Another hypothesis, if the sound does not change, could be that the system is not revealing enough and the jumper is not acting properly on the sound.

Having done the necessary tests, you find yourself needing to replace the jumpers on your speakers. Keep in mind that these should be of equal or better quality than the conductors that make up your cables Speaker - brass will not do.

For a choice without compromise, Ricable proposes its jumpers Dedalus e Invictuswith the former also optimised for the Magnus series or other lesser speaker cables. These are available in spade/spade as well as spade/banana versions. It is also possible to request a custom length. As for the speaker cables, however, the choice is more varied and takes up the four, now classic, series Ricable, namely Primus, Magnus, Dedalus e Invictus.

The skin effect in cables Speaker

What it is and who discovered it. Not only electromagnetic waves

What is theskin effect and why is it so important for cables Speaker ? This was explained for the first time in 1887 by Lord Kelvin (born William Thomson), British physicist and engineer, developer of the Kelvin scale, and engineer and inventor of the electric telegraph, with the latter securing him fame and wealth.

By skin effect we mean the tendency of an alternating electric current to distribute itself unevenly inside a conductor. Its density is higher on the surface and lower on the inside. This leads to an increase in the electrical resistance of the conductor, particularly at high frequencies. In other words, part of the conductor is not used. This means more dissipation Speaker for the same applied current or less current for the same applied voltage, according to Ohm's law.

Why it's important for cables Speaker

The skin effect is fundamental because it affects not only the electric current, but any kind of signal, including audio. The skin effect means, to recap, a decrease in current flow density as the distance from the surface inwards increases.

There is some disagreement about the skin effect and its practical consequences on audio frequencies, i.e. whether it causes any damage other than simple loss Speaker . The problems are due to the fact that, even before the loss Speaker , the skin effect causes changes in the values of resistance and inductance. These values will tend to change continuously depending on the distance from the conductor surface. If the cross section of a cable is too large, the skin effect will also affect the reproduced audio frequencies. Delicate high frequency information will be flattened with a dull sound with truncated details.

invictus speaker cables

The consequences of the skin effect

The cable "sounds" less at the reproduced high frequencies, reducing them. This problem is most noticeable in cables Speaker , where the conductor sizes are larger and the connection runs longer. In interconnects the skin effect is less influential, because it acts outside the audio band. The consequences can be many, but the most common are as follows:

  1. Dark and gloomy tones
  2. Bloated and unnatural bass (Loudness effect)
  3. Loss of tonal balance
  4. Worsening in dynamics
  5. Loss of three-dimensionality

The skin effect affects the quality of the cables and how much they affect the sound transmission, especially when we are talking about cables Speaker , running from the amplifier to the speakers.

One possible solution is to coat the wires in silver. This metal has, in fact, a lower resistivity than copper, but silver-plated cables artificially color the sound that tends to emphasize the highest frequencies, not giving the listener a neutral sound.

The solution Ricable for the skin effect

Our tests have shown that increasing the number of conductor wires, by reducing the grains of processed copper, results in a substantial reduction in the skin effect. In other words, the Ricable technology exploits the use of a single conductor small enough to expel the audible distortion induced by the skin effect out of the audio range.

Years ago Ricable introduced AM-RCC conductors in power cables with outstanding results. Since that time, research has moved towards further improvement of the conductors. This has developed on several points.

performance marc cooper leather effect

Thefirst is the multi-stranded conductor, with very thin strands down to 0.08mm in the Invictus series (and a noticeable reduction in the skin effect compared to single-stranded, also known as solid core). The second point is constituted by conductors of large section. This allows for a greater conductive surface area and lower resistance.

The third feature conceived by Ricable to reduce the skin effect is given by from RCCP connectors (Ricable Copper Connector Project). Using copper instead of brass in the connectors also reduces the skin effect in the terminations. Finally, the studies carried out and the research activity, gave birth to the new conductor MARC©acronym for Multicore Annealed Ricable Conductor, which characterizes the entire production. Primus, Magnus, Dedalus e Invictus.

The improvements made have made it possible to produce a copper conductor with 7N (99.99999%) purity that is more malleable than its predecessor, thanks to a 25% reduction in grains per metre compared to AM-RCC. This manufacturing implementation allowed to produce smoother surface strands, more ductile and smaller diameter.

We, as enthusiasts, have worked to find a solution to the skin effect that really satisfies us 100%. The differences between the cables in the entire production break down the skin effect in a unique way. Whatever your system needs, you can look through our cables Speaker .
