Soec me a 5.1 USB soundcard for powered speakers

[Skunkworks]

I've been using a Soundblaster Z for years. It sounds great, but has annoying bugs, so I'm now looking to replace it. I've tried using onboard sound, but even on high-end boards it's noticably lower quality than the 10+ year old Soundblaster.

Any suggestions for something I can use with Logitech powered speakers? It will be just for speakers, as I already have a decent USB headset.

The 3 3.5mm - Front, Back, Centre/Sub.

Edit - Logitech Z906.

Just use digital out from the PC (optical/coaxial) into the Logitech?

Onboard is never that great, even on my Crosshair 8 Formula.

I could go for another internal card, but thought I'd see if there were an appropriate external ones first.

Interesting. I have an optical cable around here somewhere. I'll give it a try.
