Audiophile USB to PCM


I have an excellent upsampler and dac (dCS Purcell/Delius) and am looking for the very best USB to PCM conversion. So far, I've tried SlimDevices Squeezebox, and Xitel Pro Hi-Fi link.

Both are very good, but I was wondering if there are any other options I should be considering. Both the Sutherland USB Preamp and the Wavelength USB Dac convert to analog. I'd like something of similar quality that stops short of the digital to analog conversion so that I can let the dCS gear do that.

Any suggestions would be appreciated.

Is ASIO something they could have licensed and baked into the ESI24.dll driver?

Very possible.
Edsilva - if you look in the "components" folder of Foobar200 in Program Files, the ASIO .dll should be there if you are using it.
Is there a good online source (Canada/US) for the Waveterminal U24? I am looking to getting started on a hard drive based system using an Apple powerbook.

Thanks,

Rene
Sadly, I gather the Waveterminal is no longer in production. So, if you can find one, its probably an endangered species. I'd just froogle it or google it and see if there is a decent deal out there.
This is probably old news to most of you, but I just noticed that the Outlaw 990 SSP has a USB input for receiving an audio signal from a PC. Their web site does not explain what type of signal (untainted 44.1 kHz?). I can't comment on the sound of the Outlaw. But it's good to know that equipment makers may be moving in this direction.
