When will CDP companies put the HDD into the box? The HDD is waaay more capable than any opticle transport for feeding into the dac section. thus: CD into tray - copy CD content to HDD (no compression - hell, keep alternative codecs out of the equation) NB: No streaming requirments required (ie no time limiting on read retries) Pull audio direct from HDD to DAC. - the AT commands required to do this are actually very similar to reading from a CD transport I cant help thinking that the worst thing about PC audio is the PC itself. Windoze, formats, compression, DRM - all these things you dont need. An extension of the CD player would be a technicaly better thing to do - but it would be harder to engineer and ultimatly I fear more prohibitively expensive due to being a lot less DIY.
