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.

Rk_t, Empirical Audio's web site (Audioengr in this thread) suggests that one should use Foobar software to upconvert to 24/96, because it allegedly is better than hardware upsampling. There may be other software that upconverts to 24/192?

At the moment, what you suggest seems like the way to go: PC card outputting upsampled digital via AES/EBU, with card driven by DAC wordclock. As long as the card is not processing the signal, only outputting an upconverted but otherwise untainted PCM signal from disk. Seems like a better solution than a USB-to-digital converter that is not driven by a wordclock. I'm new at this, so if anyone disagrees or has the best way to go from PC to DAC, I'd also appreciate the suggestions.

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.
