High resolution digital is dead. The best DAC's killed it.

Now, we can finally do discrete dacs well enough and economically enough...so R2R comes back with a vengeance, in the high end area of digital. Same for the FPGA versions of similar design and thinking as discrete R2R dacs.

And this Airist discrete R2R Multibit Dac was peanuts, around $299 or something with a Massdrop purchase, got the quota filled very quick. All 300 getting shipped next month so they say.

 As explained to me by Paul Weitzel of Tube Research Labs, who was both a recording and equipment engineer, the problem centers around engineering, engineering of the source material and engineering at the reproduction end. People fixate so much on format types and it really comes down to the quality of the recording and the quality of the equipment used to transduce it. Hi Rez formats have no relevance to me as most of my source material and prized music is Redbook.

The Benchmark DAC3 L and Chord Qutest are both more transparent. Now, you may not like hearing what your music sounds like, you may want distortion or coloration, in that case I would look at tube DACs or some poor measuring DACs from Audio-GD or similar. But if you want to hear the music as recorded, the DAC3 L and Qutest are the best for the ~$2000 price range.

Apparently nearly 2500 requests for just 300 units......

I'll weigh in as someone who designs this stuff, that redbook is in fact very very good.  In fact i have been blogging on digital formats, compression, etc and trying to undo some myths.
(Sonogyresearch.com/blog if you care)

Audiophiles' suspicion of redbook has been fueled by what can be either mis-steps or arrogant errors in the industry. Perfect sound forever (this in 1985). Bits are bits on digital interfaces a9whcih have a large analog component in timing), rotten early digital mastering and reconstruction filter.
Yet, as noted, we are figuring it out.  But some in fact were pretty good > decade ago. One stand out at its time was the Theta DS-Pro. I still have one and switch to it occasionally - and it can make great music with great recordings. Of course, like any clear lens, it can also make awful sounds with awful recordings. But that's the two-edge sword of reproduction, as opposed to production.
