I upgraded the op Amps on the sound card and the capacitors and it did do a worth while upgrade to the sound quality with more attack to the treble and a tighter bass and a lot more powerful midrange, its worth doing if you have the soldering skills, but the optical out on the sound card can sound a little muddy but with the EQ you can get around that.
Not sure what op-amps and capacitors ship with X-fi, but certainly an excellent way to upgrade the card. Pity that Creative have only just started following Auzentech and offering the option to swap op-amps on their latest cards.
You say the SPDIF can sound muddy - I presume it is configured to output at the same sample rate as the playback material ?
I am using vista 64 and found old XP 32bit to have a lot better sound for 5.1, but you say you are only using 2 channel am I correct? If so then using "play stereo mix using digital out" takes the muddy sounding bass away, so may only be Dolby digital live that's causing it because I have to use that to get 5.1 from the card as I would use my GTX480 to HDMI audio out instead, but for the life of me I can't get it to output 5.1 only 2 channel.
