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.

Ok, here it goes...disclaimer, my system, my ears, my mood and random choice of tubes in either dacs...both are fantastic, not a big difference....concert fidelity it little bit more focused, with a faster drive, with a little upfront presentation, voices closer to you. Big Six has a bit more laid back presentation, bass perhaps not quite as tight but very natural nevertheless, voices seem very midhall with a lot of stuff going on at the back of the soundstage. Lamp has a very open soundstage, where the only limitation can be source or the rest of the equipment. It is very musical dac, just like designer said not to play parts of song here and there but to just listen to music. Concert Fidelity slightly more impressive, for what its worth, with electronic music but Lamp more musical with most everything else...wish I could keep both and maybe I will but I might have to let Concert Fidelity go in the future.
PS. Lamp needs more warm up, Concert ready to go...
Branislav…..what tubes did you have in the audio stage for the L6? If you are using the stock Sylvania VT-99, you need to put those in the trash! The L6 is very dimensionally flat and "distant" with these tubes. If the Lampi guys see this as their reference tube, that is very sad! You gotta try the National Union VT-99.
Yes a great read!! Thanks for the comparison of the Lampi and Concert Fidelity. Enjoy.
Hello Branislav,
Are you continuing to compare/evaluate (fully burned in now) the two superb DACs? Do you ultimately prefer one, or are they equals performers but with different presentations? I would imagine both DACs are quite special.
