Rogue Audio ST-100

Up for sale is the lovely Rogue Audio ST-100. This is a modern tube amp with extended highs and thunderous bass while maintaining characteristic lush magic mids. It's very flexible and drives many different speakers. (Read the rave reviews in Stereophile and Positive Feedback.)

I only rate it an "8" because I'm the second owner but it's really a "9", since I can't find a scratch on it and all tubes have plenty of life left in them.
