+2 to what @mesch mesch and @immatthewj said. Three (3) different amps I sometimes regret selling. While it enabled me to go with my existing mono amps, still miss those too. Hang on to it for as long as you can, never know, might change your mind by simply doing what immathewj did.
Ever change your mind?
I put a tube integrated amp up for sale because I bought something else. So after getting a couple nibbles, I thought I better make sure everything is still ok with it since it hadn't been in the system for a couple of months. Wow....it sounds so good. The main reason I wanted to go with something else is because the system was in a smallish room that tended to be hot anyway and the tubes just added too much heat. (I've since moved everything to a much bigger, more open space.)
It's amazing how much bass this thing gets out of my Maggies. I had to check to make sure I didn't plug the subs, Anyway, has anyone else had second thoughts at the last minute? Mostly, I am just trying to recoup some of the cost of the new piece. Not sure if I am trying to talk myself into still selling it or keeping it. LOL
