I tend to agree with Greeni regarding MF digital stuff so I guess I am pretty cautious about the good impressions relating to this DAC.
I have also tended to find that MF stuff can sound great initially and goes very well in showroom auditions, but get it out into the real world for long term listening and sometimes it just isn't so good. I remember, for example, with my XCan V3, it sounded terrific against the competition in the showroom, but was pretty fatiguing when I really got down to serious long term listening. OK, so decent NOS valves solved that problem completely, but MF did not ship the units that way (for obvious reasons, but nevertheless, the inclusion of the horrible JAN Philips tubes was the way MF presented the product to the audiophile public). It's often actually the stuff that doesn't leave a big first impression which is much better to live with over the long term.
The other thing is that I am not a fan of oversampling. I've done lots of listening tests over the last couple of years and time and time again I've gotton the best impressions when the sampling rate is simply left untouched. Sure, the sound at first seems to be clearer, crisper and more "defined" with a sheen and incisiveness at the very extreme high end, but when it comes down to it, I have found it less faithful to the original source when it is heard on a top notch converter at the native sample rate.
Perhaps these 24-192 DACs might be less of a problem for me, since all my source material is 48 khz, 24 bit, so this DAC would integer upsample, but I imagine most people would be running CD sources into this. And in those instances (and to a lesser extent integer upsampling), I have found that acoustic instrument timbres take a bit of a beating and end up sounding a little thinner too as compared to simply processing the data at the native sample rate.
So for me it is a shame this DAC does not have a switch on it to turn the upsampling off, as is seen is some other DACS.
Anyway, I would be interested to see some decent up-close photos from those who now own one. I am rather tired of the single, MF-sourced picture of one proliferating over the internet.
