Grace m902

Hey! I just got the April issue from the digital subscription. The guys doing the article on the Grace m902 mentioned problems with the USB, and then the reply from the manufacture said this might have been a configuration issue.

Any update on this? Isn't this the future, getting rid of SPDIF and sending the bits in a more friendly error correcting method?

That's what they said. In the case of the Grace review, we used 4 different computers -- Wes's G5, my PowerBook, and two different PCs -- all configured correctly.

The problem with USB transmission is that it is very difficult to arrange for low-jitter clocking at the DAC, given the asynchronous nature of the interface. I am told that there is a way of allowing the local DAC clock to control the sending of data in the USB spec but no-one yet uses it.

OK, here's how out of it I can be...

I saw Grace m902 and figured it was either a vintage tonearm or cartridge article, or that the company had released a new version of one of those itmes.

Time for me to Google "Grace m902."

Well, if it can do that for your head, I'm getting one for my codpiece!

Thanks for the response. What I have been reading lately is that with all things equal, a USB into the DAC should be the better option. Of course this is all up to the implementation, and it is sounding like the m902 just doesn't cut it for USB input. Some links of interest:
