I recently upgraded my PC speakers to a low-priced set from Altec Lansing.
Not only do they sound much better then the oE speakers that came with my
Micron PC but I have no RFI from the amp (AL-811H) at all which sits about
6 ft from them. I looked around before purchasing and I concluded that
Altec Lansing had the best selection and price range. Here is the URL for
their website where one may also purchase direct online.
