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.

I hope the Playback Design was fully broken in and warmed up, because it needs it. I actually think one of its strength is 3 dimensionality, so if Concert Fidelity beats it, that would be really something.
I have done some listening tonight and the system sounds fantastic. Sure it needs plenty of warm up and sometimes a bit of help from Essence of Music cd treatment, but the clarity and 3d images of some electronic music are outstanding. Kudos to Apex Teton headphone amp, which just might be THE amp for Sennheisers HD800.
Quick update, just received my Big Six Lamp and Im currently breaking it in, want to give the Dueland Cast Capacitors at least 100 hours before serious evaluation.
I just pulled trigger on Concert Fidelity dac and Big Six Lampizator...will be curious how to stack up against each other :-)
Yes, Im very excited about the comparison and Im not going to be in any rush to come to any conclusions. A lot of people will probably dismiss it given the fact that it will be based solely on my headphone system. If there are any meaningful impressions, I'd like to share it here on this thread or I might start a new one. One of the dacs will have to appear here for sale in the future, since I cant justify having both dacs in my possession, but we'll see....The lamp should be a decked out with upgraded tube sockets and additional Dueland on the digital input....
Concert Fidelity should be shipping to me any day now and Lampizator is still being made in Poland. Im actually glad that I will have one of these dacs for a week or two before the other one comes, so I become familiar with it.
Hi everybody..I literally just got my Concert Fidelity dac yesterday. My initial impressions were a bit inconsistent since I'm also breaking in a brand new headphone amp and upgrade cable since the sound would slightly change. I did notice the tube swap does impact the sound noticeably. I will post further impressions soon and especially will be able to evaluate and compare once I get my Big Six Lamp, which might be early next week, since I can only comment how my system sounds overall without being able to pinpoint how different pieces of equipment contribute to the sound. Stay tuned...
Hi Matt (if that's your name)...definitely keep us posted those are some heavy hitters you got there....
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...
I have been fairly busy so I havent had as much time to listen as I would have liked. Yes, I think they are on the same level, just with slightly different presentation, which could be due to tube choices. Ultimately Big6 is staying put and Concert will be up for grabs when I get around to it.
