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.

Absolutely, I have been trialling an Esoteric K-03 as potential transport this last week, which works very well with the DAC040BD in fact, but in comparison with the internal dac of the K-03, the CF/BD is in another league. In comparison to the SACD section, redbook cd (DAC040BD) is very very close, more organic and less fatiguing, but with hugely impressive dynamics. Playing Ivan Fisher/Budapest PO Mahler's 1st Symphony yesterday was no less than absolutely spectacular, the weight and scale, seriously thunderous LF, truly amazing.
At first you hear a much quieter background as if the noise floor has been lowered. Perhaps RFI and EMI gremlins are lessened in the source playback chain. Frequency extremes are extended. The bass is deeper and more organic. Tonal purity, accuracy and definition are superbly rendered as well as soundstage width and depth. It's as if the source has "slowed" ever so slightly to allow every aspect of source reproduction to be improved. Digital becomes softer, sweeter, more involving and far, far less mechanical sounding. The battery upgrade is not subtle-you will hear it's effects immediately. The BD upgrade takes a superb DAC to a significantly higher level of playback enjoyment.
Hello,

No, DAC 040 has hand built transformer to match your country's voltage rating. It is very high quality WB transformer.

Best Rgds,

Paul.
Hello Guys,

Last night I finally got to audition the CF-040 with the new battery based power supply along with the original DAC in an all Concert Fidelity based system.

No, the difference is not night and day, it does not "blow" away the older model, it's an evolution not a revolution and I did not want to throw out my CF-040 when I got home to listen to my system.

Here's what I heard: 1) More liquidity and ease without losing dynamics. 2) More extension and air/details on the top end. 3) A bit more image density.

So, congrats to CF for further refining a world class piece and taking it to even a higher level of performance then the last generation of this DAC.
