I see the problems, wonder if logitech ever is going to develop a squeezebox with hdmi then you have a standard interface that takes multichannel pcm ,8ch as the standard is now. Your idea needs some purpose built converter recieving multichannel pcm over usb hmm. if you have annhtpc with hdmi you can probably play these files. but the bigger problem is the lack off content, most vendors like linn and HD- tracks does not have such files, you get them by ripping your own DVD-A and the odd old quad master leaked to the internet. Itrax sells 5.1 pcm hirez but itrax AIX does not release much these days ? So it's a great missed opurtunity not even audiophiles wants it , they are happy to buy 40 year old analog masters as 24/192khz 2ch -- Mnyb -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.
