It's hard to describe the difference in words. I will necessarily sound like always.... But I'll give it a try. In favor of the Touch: - PC sounds somehow thinner - Touch is somehow warmer In favor of the PC: - sounds more effortless - harsh recording passages have less ringing (piano, violin) - less fatiguing My hardware is an Intel HD 3000 with HDMI out (integrated into Sandy Bridge processor). And as far as I can remember WASAPI is the bit-perfect Windows alternative to ASIO (Steinberg). I get the same results if connected through USB and WASAPI. There is no processing involved, neither on LMS nor on foobar. ------------------------------------------------------------------------ Quad's Profile: http://forums.slimdevices.com/member.php?userid=20234 View this thread: http://forums.slimdevices.com/showthread.php?t=98374 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
