Upsampling / Oversampling DAC


I am looking for a list of the very few high-resolving-power DACs available. Now that 24/96 is old news, and even 24/192 is commonplace, I am curious about the 24/768 units. I know about the Boulder and Dodson, but surely there are others. What else is available?

Gthrush1--don't expect a DAC any time soon, if ever, for decoding DVD-A, as the discs themselves at this point won't let you pass a digital signal at the higher bit/sampling rate, and SACD decoding will depend on whether an industry standard interface for sending a DSD signal is adopted (for example, my Audio Logic DAC will decode a DSD signal because it takes the pcm signal and converts it to DSD in the DAC--a number of other DACs are designed this way too, I understand--but since there is no standard interface I can't take a DSD signal into it yet). I would expect dCS to offer something beyond their 24/192 standard at some point if they get caught up in the khz race, and they can decode DSD (and use their own interface to do that) in their current models. Quite frankly, I am not convinced I hear ANY difference between 96 and 192 khz sampling rates with the dCS gear I've heard, and wonder whether all we're really looking at is marketing to get us to believe our two-year old DACs are now obsolete. Of course, my ears are getting old, and I'm also getting somewhat cynical in my old age.
As much as I am a supporter of SACD, I don't mind in the least if a 32 (or 24) bit standard takes over--all of them are or would be better than 16 bit redbook CD. The problem is convincing the masses to accept something other than CDs, which these days are sounding better than they ever have.
Another part of the problem for us perfectionists (nuts?), I suppose, is that for a while we will be stuck with less than high-end equipment (the Sony SCD-1 and 777ES were comparative exceptions, and due to their excellent transport mechanisms were great platforms for mods to the analog stage) on which to play the new format until it's established and the high end manufacturers can risk putting money into it. I might be interested in a high-end DVD-A player, since I can't use my 24/96 DAC to play the discs (which does tick me off), but who among the perfectionist manufacturers is going to make one till the format wars are settled? So while I hope SACD catches on, I agree, redbook CD will be around a long time--that's why I bought a Purcell a couple of years ago. Always hedge my investments...
