Laurence Payne in uk.rec.audio:
I wish someone would make a serious-ish amp with a 'usb-in' socket, so
the computer recognises it as normal, plug n play, digital speakers,
bypassing a soundcard altogether. I suppose that won't happen until
the stigma of pc audio is gotten over.
Plenty of cards with digital out, and amplifiers with digital in.
Can't see the point in converting to something USB can handle, just to
convert it back at the other end?
If an amp is going to have digital ins anyway, it would mean little extra
cicuitry to include usb as well as spdif etc.
Unlike games, music reproduction presents very little processing to the
soundcard, the decompression from mp3/wma/ogg is done by a codec running on
the main cpu, with a soundcard just providing a dac or, if using digital
outs, an overcomplicated adapter.
It is no more difficult for the pc to send small amounts of data to a usb
device than a pci one. Running a usb connection to an amp means a £3 cable,
in place of a £50 soundcard with digital outs.
IMO A usb system is also much more elegent, with fewer different connectors
and plug 'n' play setup.
