Devialet Expert Event

Devialet recently did a demonstration between their Expert Pro series and the preceding generation models at their Singapore dealer - Audionote Singapore.

The first demonstration involved a comparison between a pair of Devialet 400 Mono amplifiers, and a pair of the latest Expert Pro 440 amplifier. The rest of the setup comprised of Raidho speakers and an Audionote CD transport.

Regrettably for the 400 Mono owners, the comparison was to me utterly crushing. The 440 had more control, authority, sweetness and refinement. The demonstration material included fairly  dynamic test tracks played back at high volumes - the 440 really shone here with a lack of strain compared to the 400. Dimensionality was also much improved, with a superior rendering of acoustic space and sonic images.

The next demonstration session had a pair of Avantgarde speakers paired with the Expert Pro 1000 monoblocks - this time with an analog front. I've heard Avantgarde speakers before. It was marred by amplifier noise - the resultant hum was deafening through the high efficiency Avantgardes. Devialet was obviously not the least bit worried - the speakers were dead silent, not a trace of hum or noise. Sadly, I had to leave before the demonstration started proper. I did get to hear the warmup records ..... RIAA equalization in the digital domain ! Sounds like heresy, but frankly if they had covered  covered the Devialets up, I would have been none the wiser.

Daedalus Audio DiD and LessLoss Bindbreaker Footers

Daedalus Audio DiD

This is my first encounter with a Daedalus Audio product. Daedalus is the father of Icarus in Greek mythology and a skillful craftsman and artist. The story of the wings fashioned by him to enable the escape of both Icarus and himself is most well-known - in particular, the tragic end of Icarus who did not heed his father's advice not to fly too high lest the wax holding the feathers together melt.

Coming back to the present time, Daedalus Audio is most well-known for it's hand-crafted speakers, featuring hand-crafted cabinets and high efficiency designs without the use of horns.

The DiD (Daedalus isolation Devices) are footers that use dissimilar materials to dissipate resonance coupled with bearings to isolate the component from vibration. The DiD is made from highly polished Aluminium, solid Cherry and Brass with steel bearings.

Additional felts pads are supplied to further tune the sound. A smaller pad fits in between the bearings and the wood top, while a larger pad can be used under the base of the DiD. I did not use either of the supplied pads since I needed the return the DiD after evaluation.

The DiD is very nicely made and all parts fitted together with very close tolerances. This is certainly made with pride and it shows !

Sonics wise, the DiD falls somewhere in between a bearing type footer (e.g. the models from Finite Elemente and Stillpoints) and wooden cones, combining precision with warmth and smoothness. It cleaned up the soundstage, improving placement and separation of instruments. It also added a very natural decay to notes. The warmth and smoothness imparted is quite subtle and you never get the feeling that information is being obscured or smoothed over. If you like your music sweet, overtly warm and with a lot of bloom, the DiD will not satisfy. Neither will it tick the boxes if you like your music with a razor sharp edge and pacing with military precision. Instead, the DiD strikes a careful balance between both. Who says you can't have your cake and eat it ? This is an easy one - Highly Recommended.

LessLoss Bindbreaker

Here is an accessory that sounds more like a magic spell. LessLoss should be a familiar name to many of you, with their reputation made on their power cables and conditioners. 

The Bindbreaker is made out of three parts. The small wood hexagon on top is connected to the large midsection via a hard metal bolt, and has a small amount of free play built in. The idea is to transmit vibrations rapidly to the steel plate underneath, and the matrix of attached bolts. The bolts in turn transmit the vibrations to the bottom wood hexagon which damp the vibrations. 

I noticed that in practical use, not all the steel bolt heads would make contact with the bottom wood hexagon. I would guess that the wood would flex slightly under heavy weight, but certainly not under my rather lightweight Totaldac DAC.

Sonically, the Bindbreaker is cooler in tone compared to the DiD. It cleans up the soundstage and improves imaging, but it has a more analytical presentation with drier albeit tighter bass lines. While the Bindbreaker never sounded sharp or sterile, it had less bloom, with tightly focussed images. The sense of air and decay was also less. 

While I preferred the DiD in my setup, the Bindbreaker turned in decent performance and is worthy of further investigation - it really is a matter of taste.

Both the DiD and Bindbreaker can be purchased from Horizon Acoustics. Thanks to KM Poon of Horizon Acoustics for his review samples !

Black Cat Cable - The Tube Extreme RCA cable


A very long time ago when I was a wee little audiophile, there lived a cable designer. His name was Chris Sommovigo and he designed a really famous digital cable that become the go-to cable for SPDIF use - The Illuminati D-60. 

Now, wee little audiophiles don't have a lot of money, especially ones that did not have a part-time job, nor rich parents. Hence, I never got that D-60, and after much sleepless nights worrying about signal reflections as a result of impedance mismatches, I took the cheap way out and purchased some 75 ohm coaxial cable used for TV aerial use and soldered some RCA connectors on them. 

Illuminati eventually got acquired by Kimber cable, and Chris ended up starting a few other companies such as Stereovox and Black Cat Cable. I finished school, got a job and can thankfully now afford some audiophile toys for myself from tome to time.

Recently, Black Cat Cable offered a limited run of a modestly priced RCA cable, "The Tube" with the very sexy XOX connectors. To a weak-minded audiophile like me, this was like dangling fish before a very hungry cat. My brain is programmed similarly to that of a cat, and I never say no to food. 

A short while later, a package arrived and the unboxing ceremony was an event in itself. I am very fond of Japanese packaging, and as far as I am concerned, this cable box could very well pass itself off as a presentation box for my many beautiful Japanese fountain pens.

I ended up loving this cable as much as my many fountain pens, except that this cable actually cost much less ! 

Black Cat Cable - The Company  

I had read about Chris's move to Japan - a small seaside town in Kanagawa prefecture. A move from an American city to a small town in Japan - that's really quite a change ! 

Chris was kind enough to answer some questions for me, and here is his verbatim reply (except for obvious typo corrections) - 

Q - Chris, your approach is really different from other industry participants. You choose to run your own winding machines, and even terminate all your cables yourself. This is really different from the new world order of getting an OEM manufacturer to fabricate a cable for you in bulk. Any insights as to why you choose to pursue this route that is a lot more difficult - both in terms of resources and scalability ?

A - The traditional methods of manufacturing cable from the industrial segment rely on big thermoplastic extrusions being squeezed out over bare wires, and this more or less limits the expressions of design that one can indulge in. There’s nothing inherently terrible about that approach - 99.9999% of cables sold in the consumer electronics industry are produced in this way.

The industrial model relies upon routine processes, and so when it comes to cable designs most companies have to shoehorn their intentions and desires into the existing paradigm of the industrial routine. I wanted to do some unusual things that were not really plausible from within the industrial model of manufacturing, so I had to figure out how to do them in my own workshop by creating and adapting processes and machines for my purposes. This has taken several years of continuous development, and evolutions in my thinking about how to approach the basic architecture of building a cable from raw materials. I’m at a point now where I’m satisfied that the processes are fine tuned and I can express my design motifs confidently.

In terms of scalability, these processes can be scaled up, but I’m not certain that I want to expand too much. My intention is not to be fighting for market share in all the top distributors and dealers around the world. To do that effectively and compete against the well known brands you have to do what they do: offer 80%+ margins, spiffs, free product, and on and on. I’m just a little guy … I can’t play those games. I can’t get in that race to the bottom.

What I do is highly specialized, and so I think it is better to keep the scale modest. Yes, there is room for some expansion, but this is High End Audio … not general consumer electronics. For my own philosophy, I think that there needs to be a degree of art and artisanship in what we do. We have to earn our keep in this way by producing authentic and specialized products for people who appreciate fine things. By the nature of that philosophy, this can’t be done on a large scale and it can’t be done cheaply. 

Q - I feel that your move to Japan really resonates with your product ethos. The culture there really believes in pride of workmanship, regardless of whether the job is simple or complex / highly skilled. Any comments ?

A - I think of Japan’s traditions of artisanal expertise coupled with the reputation for precision as a kind of ideal mix of characteristics. There’s a world of extraordinary craftsmanship here that connects past and present in ways that are really quite nourishing and enriching to the soul. I don’t dare think of myself in these terms, but I deeply appreciate and somewhat idolize people here who have mastered their crafts and who preserve their traditions. I’m in an environment that suits my way of thinking when it comes to my products and my art, and it’s quite nourishing to be immersed in this world.

Q - You are one of the very few in the industry to use proprietary in-house designed connectors. The Lovecraft and XOX connectors. Could you tell us a bit about these connectors ? I noticed that you don't follow the current trend of low-mass designs.

These are neither low mass not high mass, really. They are suitable for what I need them for, and there is an advantage to the way in which I execute the pin designs: they are a direct-gold plated copper hollow pin with a set screw. There are raised edges inside the pin so that when I use the set screw to tack down the conductor, the edges bite into the conductors and ensure a very low contact-resistance. I then flow solder into the joint so that there is some strain relief and also so that it forms a proper hermetic seal.

This approach is fundamentally excellent for making electrical connections such as these, but I never found any connectors available that had all of these attributes together. So I designed my own. These are quite a departure from my old Xhadow designs. Most obviously I am not using silver-plating any longer. I do like it better than gold plating, but the problems of tarnishing over time were problematic and erased the benefits of using silver plating. Although I retain the set-screw approach that I designed into the Xhadow connectors, the obvious departure is the hollow pin and the raised internal ridges (which I think is original and a bit clever). 

Q - Your geometries are quite complex. I guess that simple geometries didn't quite cut it for you ?

A - Simple geometries are effective to a degree, and they certainly fit into the industrial routines. I had different ideas that I really wanted to express, ways of ensuring high velocities inside the cable, and ways of making certain that they weren’t suffering from skin effect and proximity effect. The Matrix and The Matrix Mk. II are probably my most complicated builds that are in production, but upcoming will be my Super-Reference “Indigo” and that adds a new dimension of complexity to the approach I use with The Matrix.

But there’s also something positive to be said about distilling ideas into very simple and elegant forms, and to this end I have a project, called “AIRWAVE”, that is based upon the distillation and simplification of something that was designed during the Indigo development cycle. It’s not nearly the same as what’s being done for Indigo, but it benefits by the approach and allows me to create something very good and yet quite inexpensive. I’m quite excite about AIRWAVE because it’s going to bring some seriously high performance to folks who want entry-level products. 

Q - Any chance we will see power cords in the future ? 

A - Perhaps. Probably. Possibly. I don’t know … lots of folks ask me about them. Maybe it’s time.

The Tube Extreme Cable

The XOX RCA plug up close. Puts most connectors out there to shame.

Since we are on the topic of artisan works of art from Japan, here is a picture of my Nakaya Piccolo Arai-shu fountain pen. Ebonite body and Urushi lacquer finished.
