Jrud- Just a word of caution. Listen before you buy!!!! OK, actually, a few words. Reviews are at best a positive when it comes to resell an item, but they mean very little in terms of your potential enjoyment. If possible, I'd suggest considering a new amp that would have a money back offer, possibly a PS Audio or some other manufacturer with a similar offer? Most used gear isn't available with an audition clause as part of the sale. Just curious, but have you considered a good tube amp instead?:-)
Good luck.
