Worlds best DAC

Went to CES this year to work on my transition to high Rez digital. I've heard many of the highly regarded players in my room or in others systems in the past. I'm actually very happy with my current cd based sound. As I listened to various DACS playing CD then high Rez, I was not bowled over. High rez was better, but only slightly so. The best (and most different) sound I heard happened to have one similarity. They were 2 non oversampling DACS with tube analog stages(Zanden and Ypsilon). These were without question the most natural sounding digital systems I heard at the show. They made CDsound miles ahead of high Rez. What gives?

PS: I understand the limitations of show auditions.

The new PS Audio perfectwave DAC performs best in non- upsampling ("native") mode. The new MKII upgrade has some innovative circuitry on a new digital processing board, involving changes in the powersupplies, and replacement of CMOS switching for the gates and clocking with analog switches. It also implements new jitter reducing circuitry called NativeX. I will get my upgrade tomorrow, but the first reviews are extremely positive. Wonder how the MKII ($4,000 MSRP) would stack up against the mega bucks units mentioned here.

I think we are too hung up on the merits of "computer files" versus "CDs". They are both the exact same data. What matters are the timing errors in the transfer of this data to the DAC. In typical synchronous transfer mode, the transport provides the clock to the DAC, so it stands to reason that whatever transport provides the most accurate clocking sounds the best. You can get USB converters with very good clocks - better than what you find in any CD transport. This is why with the top notch hardware computer audio typically beats CD.

If you go by the consensus of guys that have rotated the usual suspects of high end dacs through their system, I would say the top dog is the MSB Diamond. This consensus is not unanimous of course, but most folks with no budget constaint hearing it will say it bests all else they have heard and end up buying it.
