I'm in alignment with Mapman.
Auzentech looks like it keeps up with Windows OS upgrades. X-Fi Forte 7.1
Low Profile PCI Express Sound Card would be my choice. I would also look into
if they have upgrades for Windows 7 which was released Oct 22. Also note, the
Forte has a Hi-Fi OPAMP, headphone amp, and Coaxial (left) and Optical output
(right) output.
What is your external DAC?
Dynaudio MC 15 and Quad 11L have great sound qualities without using a sub. I
also like very much the Bang & Olufsen BeoLab 4 Speakers for PC or Mac which
is closer to audio experience of a floorstanding loudspeaker. The Adaptive Bass
Linearization offers superior bass performance from this small cabinets.
Incredible rich and smoothness from the OEM of ICE technology.
