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.

Edsilva - I look at a PC as a general purpose tool, and a very flexible one. It is like having a set of adapters and sockets with a socket wrench rather than a set of open-end wrenches. The sockets can get into tighter spots and the sockets are interchangeable. You can change the way that the socket wrenches work and their configurations. The open-end wrenches are good, but have limitations. They only work one way with fixed sizes.

DSP processors have certain ways of doing data manipulation. They can be faster at doing some things than software. Software really has no functional limitations, just the size and latency/speed of the code. Hardware is the most limiting for implementing upsampling codes. This is why hardware implementations are usually outdated quickly and do not sound as good. Not that a good code could not be implemented in hardware.
Onhwy61 - I have used and modded the Big Ben. I found it to work exceptionally well for reducing jitter. The effect was immediately noticable. Deciding whether it is worth the price for what it does is up to each individual. It also has the benefit of displaying the input sample rate.
Edsilva - does your waveterminal have a driver that you load on the PC?
Audioengr-

The Waveterminal does have a driver, but after poking around, I think its limited to 24/96 output tops, and I believe the 96 may, in fact, be an internal upscaler. I think, if I read right, that its 44.1/48 only.

Oh well... It still sounds damn good run through the dCS Purcell and Delius.
Edsilva - If you open the volume control for windows using control panel, do the sliders have any effect on the audio??

Just wondering if KMIXER is bypassed.
