what's crappy most?
SPDIF or standard USB adaptive crappy way used to recover audio clock?

IMO this interface is solving the problem for eliminating PC->USB introduced jitter .. similar approach (very cool) it was achieved by wavelength using tas1020.. 96khz limited and not cheap.

I don't like SPDIF either, I'll try tapping I2S very soon and I'll post results.

Not an easy task: the resistors are so small that the simple "attaching" of a wire can damage them (imagine why I know it!

).
However, with some skills of microsurgery

and a powerful loupe is feasible (even if not advisable: see warning about the warranty).
Anyway, DON'T TRY THIS AT HOME!!!!!

In the next days I'll be able to post some results.

At least (hopefully) a good USB - SPDIF interface will bring computers to the standards of good CDP or better. Then SPDIF to an external DAC, it's all the same.

Unless talking about interfaces better than SPDIF, but then you'd need a DAC with that interface, and it's another market altogether.

I2S out, now you're talking.

I actually find the optical out from Mac book plugged in my CA840c cd player/dac to sound slightly better than the cd player itself. i guess the lack of spinning transport and power supply draw in the cd player is audible.

PC as a transport have better sonic performance. For desktop PC easier and better to use Profcards, he has synchronization from spdif input and you can achive performanse similar to IIS bus (if you properly build you DAC)

Can MUSILAND Monitor 01 US does Asynchronous transfer as well?
How does the M2tech better than Musiland in this case?

Thanks.

...let's just say, it should be apparent to anyone 'remotely skilled' how "good" are these, at the first sight

Ipanema · 13th October 2009, 06:05 AM

Good in terms of what? Do you have jitter measurement comparison done on these device yet?

tritosine · 13th October 2009, 06:12 AM

once someone donates one I can sort it out, cause I refuse to buy "labels".

It would be awesome if they would also release this technology as a DIY kit (on a separate board, with external power support) so we can integrate it in DACs and skip the conversion to SPDIF.

One can only wish.
