Audio Research VSI-60 50 watts 6550 tubes Stereo Intergrated Amplifier. This amp was bought by me new in the box. Went through a divorce so it went back in its box soon after buying it and the original tubes have not even been broken in yet. This amp has not been near smoking, children or pets, adult owned with very very limited low use. If you want a VSI-60 that is practically new then this is your ticket for a great amp at a great price. Sounds awesome beautiful bass, mids and highs. To match this VSI-60 one would pay 3 times for a separate pre-amp and amp Audio Research did a great job with this intergraded amp sounds amazing. Perfect amp no marks or dings its perfect with its box, remote and manual. Price includes shipping in the contiguous United States sorry no Alaska or Hawaii. No returns the amp is perfect. I'm selling my speakers and CD player also.
