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.

Kfreichen - to answer your question, I now offer two products, the Off-Ramp Turbo and the Freeway that are modified Transit boards with external power supplies. I also offer a battery power supply for them. They both convert USB to digital coax, but the Off-Ramp has a Superclock3 as master clock. These are very low jitter sources that can pass 24/96 data upsampled by Foobar.

I just installed my u24 and run itunes with Apple lossless into my Meridian 861 v4 and can say it is on par with my 800 v4 reference dvd player/transport. This is mind blowingly convenient and sounds phenomenal.
I use the u24 and run itunes with Apple lossless as well, and run it into an Apogee Mini DAC. Incredible combination.
Ultraviolet -- hey man, the U24 came first so I've had it plugged in and have not tested the Audiophile. Unfortunately the weak link in my system is my larger than life ROOM! It is 45' l x 24' w x 20' h. Yeah, 20' ceilings. You wouldn't believe how these ML Request electrostats disappear in this room.

So I am probably not the best judge of source sound quality right now... U24 sounds good to my ear though, no better or worse than a CD source (although I do not have a high end CD source). Will let you know here if I decide to pull this Audiophile out of the box. Thanks for all your posts.
What is wrong with using your SB2 feeding into your dCS?
I am going to use the SB2 feeding into my EMM Labs...
