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 Fluffers,

Welcome.. Yes, the DAC has to be returned to Japan, this upgrade is not user installable at all, it involves new circuits and very high precision fitting and testing. With regards to the used DAC040, try to establish whether it is V1.0, or V1.5. Both can be upgraded though. V1.5 is newer version. Are you US based?

Cost is set by your country distributor, and will be around $3500 for the upgrade without AC back up, and $5500 for a complete rebuild to current spec, inc AC back up. This will involves replacement of everything except the chassis and HV power supply board. If you combine the full rebuild cost with the used price of the local DAC040, you may well end up with one of the very best 16bit DA convertors around, the upgrade is simply stunning. I have both units side by side, the BD is a significant development!

Let us know what you decide, happy to help..

Best Rgds,

Paul.
Hi Cyrus,

Unplug and let valves cool if needed, unscrew top cover with 2mm hex supplied, look at the rear upright PCB, right hand side, lower edge, it will be printed there..

Great posts guys!

We have a CF DAC 040 BD on order and should be here in about month. Once received, we will post about differences between the BD and non-BD versions as we will also have them side by side.

Heck, maybe if I ask nicely Teajay will even come over and do his own mini review :o)
