With regards to source, we have a few R&D projects going on. One closest to release is a PC in Ref 9 chassis. Don't laugh. Intel core-duo CPU, fanless, all the PC I/O (ethernet, firewire, USB, serial ports), plus S-video, HDMI, coaxial/SPDIF out, 7.1 surround sound decoded output, etc + DVD/CD. Oh, plus 3.5" harddisk all inside a Ref series chassis. Yes, it is going to run Windows Vista.
For audio listening, take the SPDIF out into a high performance DAC (also future Nuforce product) and then to P-9.
Ok, as you can guess, R&D project might not make it into a product if we hit some roadblock or receive poor response. Is this something you want?
