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.

Correct me if I'm wrong but are you guys doing all of this and still using Windows sound drivers? Hopefully you are utilizing the ASIO USB driver and selecting it in your Foobar output preferences. Just curious.
Edesilva - I got a deal on a U24 a few months back. I'm running the V 2.61 driver. My control panel doesn't say ASIO 2.0, just an ASIO "logo" in the corner. Foobar recognizes my U24 as an ASIO capable output device. I believe the capability is inherint to the esiu24.dll. No ASIO dll in my system files either.

Would like to experiment with the upsampling and SRC however I am content with my 44.1 performance. I have experimented with the Convolver DSP plugin. I have acheived my absolute best sound utilizing ASIO ouput as well as this plugin. Specifically utilizing an impulse entitled "SPL GoldMike Impulse.wav" On some slightly "brighter" recordings I have had excellent results with a "neutral.wav" impulse. I believe I got these at a site called www.noisevault.com

I did try a friends DIY NonOS DAC with the U24 (less the Convolver plugin) and the sound was easily bested by the plugin utilizing the GoldMike impulse. The plugin does not increase CPU usage on my computer at all.

At any rate, Convolver is a great plugin in my camp - but be worth a little experimentation in yours as well. Have fun.
Go on Ebay and do a search for "USB to SPDIF Converter". There is one on there now for $35. Then go find an EAD DSP-7000 MKII DAC on the cheap and I think you will experience a life changing event for around $300.
