Best 2.1 PC Speaker System?

Videologic Sirocco Pro. Nothing else comes close.

Aego2, I agree with Hueske.

How many PC speakers have a total of 6 amplifers?
2 per satellite (bi-amped), and a bridged pair for the subwoofer. Toroidal transformer, 40,000uF of filtering.
and, oh, yes, XLR connectors. On-board DAC that rivals many commerCrap CD players...

I listened to everything out there and ended up buying the Logitech THX setup. There are 4 sat speakers + a sub, so your sound card needs to be capable to handle this setup. The price was reasonable at under $200. Do yourself a favor and listen to systems side by side, I did and the Logitech were better to my ears than other units mentioned here. Don't think because one system is twice the price of another that you are getting twice the sound, you won't. This system was bought for my son's dorm room in lieu of a hifi setup and I marvel at the quality of the sound every time I listen to it.

I'd try to find a pair of used Jamo CS5 and a small sunfire sub. The Jamo's are great, I even take them into another room for just plain stereo VHS movies. I suppose the only problem is they are no longer made by Jamo. But they have two bi-amplified speakers, and sound great.
