Dima for instance (and he has quite high expertise in the subject) claims that there no true 24bit converters available anyhow. BTW, with all advances of HDCD, that I fully appreciate, it makes send only on 16 bit. At 20-24 bit I personally was not able to see any benefits of HDCD of any custom jitters. So, I do not know how advantageous would be the Berkley HDCD is you play 24/88

He WAS right. There WERE no true 24bit ladder converters before that MSB and the Q5 DSP of Anagram Technologies, that has not been implemented in any commercial DAC yet, as far as I know. Link here:

BTW I have a Fim 24-bit HDCD that sounds marvelous on my VRDS transport, and the DAC is less than 24 bit. It could only sound better on the Berkeley

| Excuse me Romy, which soundcard do you employ and how is your poser? I assume that it is not inside your DAW. How it is connected to the computer and to the DAC? I think that you are using the pro Lavry DAC at the moment. | |

I use Lynx-16 and it is inside of my DAW. I selected it base upon the minimum on-board processing. My point was that it one use externals card and if the fw800 is not a bottleneck then the card might have DACs on board.

If you are not using the Lynx DAC, how good it is really does not matter. Isolation from computer noise matters most IMO. While the Lynx is very good, I still believe you can get slightly better using a firewire interface as digital transport. Also Check the lenght of the cables. I think up to 5m is safe for firewire. I'm not sure about spdif (optical or whatever, these interfaces confuses me). You may want to try with a fireface 400 (i'm assuming you have a firewire controller).
Also, let me know if you try different file formats. Your audio chain is one of the best that I know and being high-efficiency is very revealing. For instance Linn records makes available test files in different resolutions and formats. Another site that has a (free) evaluation is this:

| No, its not bogus at all Just very spartan design (first case, like mine, was better looking btw). 5V? Not sure, but I read of quite some DACs outputting 2V.Anyway, if you try it, let me know. I think retail price is under 2000€. | |

Nope, I will not try it, I have no motivations or need to try DACs, I might try, juts for a hell of it the new Berkley DAC to see how it will push against the Lavry DA924. I might also try in future one unique DAC that Dima invented, the one that has no analogue with any other DACs even made my mankind (pure analog DAC!!!!) It pretty my deplete my interest in DACsThe Cat |

Okay
I think I will try the Orpheus Prism (they rent it, one day rent will do the job when my DAW will be ready). And something that Peter is working on.
