I purchased the Bose Media Mates a few years ago and connected them to one of my computers. They sounded good but I noticed they couldn't handle real high volume without distorting and they had no surround capability which I found out after the fact, and so I took them back. Maybe they have improved the quality and capability over the years though.

I use a pair of Altec Lansing ADA 305's/w subwoofer with my PSR 2000 when not using my Big Guns, ie., my Pioneer HPM-100's. They fazed out the ADA 305's over 3 years ago but I still find them more than adequate to supplement my PSR 2000 speakers. It's amazing how the quality of sound improves with just these small speakers and a Sub although the PSR 2000's speakers are great by themselves in a small setting or for practicing.

Best regards,
Mike
