Review: Concert Fidelity DAC-040 DA converter


Category: Digital

Starting in 2005 I worked myself up the chain of the very fine DACS built by Accustic Arts of Germany, finally ending up with their Reference Tube Hybrid. I have auditioned over six very highly regarded DACS in the last couple of years and found them to be quite good, but none of them exceeded the performance of the AA Reference Tube Hybrid in my system. I do not use high resolution material, only Redbood CDs, so these auditions were only based on this format because my large collection of music is composed totally of this material. Well, I know nothing is the "BEST" in high end audio, there are many fine pieces of gear when you get to a certain level of excellence. However, I thought that maybe the evolution of DACS that play the standard format had got to the point that it could not get really that much better. Each DAC might offer different slight flavors but not a qualitative shift to a much higher level of performance. It has turned out that I was very wrong regarding this assumption after auditioning what has become my new reference, the Concert Fidelity DAC-040.

The designer of the CF DAC-040, Mr. Masa Tsuda believes in very short and clean circuits in all of his designs. The analog section of this DAC is very similar to what he uses in his highly regarded reference LS-080 linestage. They both use 12AU7's and a 6CA4/EZ81 full-wave rectifier tube. It took over two years of on-going listening tests for Mr. Tsuda to find the NOS DAC chips to use in his DAC, there is no over or up sampling and any type of digital filters to be found any were in this piece, that delivered the sonics he was looking for. Which DAC chips he finally decided on are confidential and not disclosed. All the Concert Fidelity and Silicon Arts, same company, pieces are beautifully built to an exemplatory level including the DAC-040.

Why was I taken so aback by the sonic performance of the CF DAC-040, here's the reasons:

1) By far the most natural timbres and harmonic colors I have ever heard coming from a digital front end.

2) The microdynamics and prat of this DAC are amazing, yet it still allows the listener to relax into the music without giving up the punch and kick of the music.

3) What I refer to as image density or a 3D quality, what most would just call palpability, of each player with air around them on a layered soundstage was the best I have ever had in my system.

4) The CF DAC-040 creates a very open and deep soundstage with great layering in a natural way that allows you to have the illusion that your in that acoustic space.

Believe me, the AA Reference Tube Hybrid DAC is no slouch in these sonic qualities, yet, it was no were close to having these special attributes that the CF DAC-040 was providing in my system. To use very subjective terms this DAC has the most musicality/naturalness that I have experienced that just draws you into the music. Dare I say that a lot of listeners could be fooled into thinking that they were hearing an analog front end, instead of a digital source, I think so.

I end all my reviews by sharing that there is no "BEST" piece of any kind of gear, but many terrific ones. Personal taste and system synergy always comes into play. If your looking for one of the best Redbook DACS around today I highly recommend you audition Mr.Tsuda's "baby", you will be in for a sonic treat.

Hi Paul,

great news!!

With the 080LsxV2/ZL120's/040 (of course) and maybe MT top CDT, your system will be absolutely awesome ;-)

I would like to tell you my personal opinion about Kalista VS Calypso CDT; if possible, Paul, try to get a Kalista Ref.

IMHO, the Kalista features are better than Calypso; for example in the K. there are two acrylic plates, in the C. only one (also the K. Ultimate SE have one plate but its depth is about the double of the acrylic C. plate).
In the K. the cones are in stainless steel, in the C. are in anodized aluminum.

In any case Paul, my suggestion is to choose the Reference version with the Elektra PSU and Silent Base.

Thank you so much for your NOS tubes advice.

Best regards,
Hello Piermauro,

Again many thanks for the info, i will most likely try to find a Kallista in due course, there are few in the UK but i know our distributer so maybe i will try one ;-)

Some news from Japan, i need to check whether i can discuss it yet here, but an upgrade to DAC 040 may be available soon, more details to follow..

On the tube front also, ECC 802s for classical, it works so well. I swap tubes depending on music preferences..

Best Regards,
Paul.
Ok, so the DAC 040 (V1.0 & V1.5) is now upgradeable to BD spec. This involves the implementation of a Ni-Mh battery drive (automatically rechargeable) for the digital to analogue stage. Those that have heard this modification by Concert Fidelity in Japan are impressed and excited. Each countries distributor will know more soon!

All being well, we will have a new unit for comparison by christmas, so will update again then..

Best Regards to all..
Paul.
Wonderful news! Thank you so much indeed Paul.
I will contact ASAP the italian distributor.

Pls, Paul let us know about the comparison.

All the best,

Piermauro
No problem Piermauro, i will let you know as soon as we have the upgrade
here in the UK..

We have the 080 and 120 amplifiers here also now, they have been installed
for just two days, just incredible transparency..Also fast, with wonderful
texture and tonality.. This is state of the art, in minimalist circuitry.

Best Rgds,

Paul
