WOW, What a rave review. I wish my Marsh 400 was that good. I think the Marsh is a fine amp and a great bargin. I use mine as a back up amp and for times when I need the power. I agree with many of the things that J_c stated. I do think another point of view is needed. If you have 8 to 15 grand to spend on an amp you can do MUCH better. As I said, I think this is a fine amp and can compete against amps in the 5k range. My tube stuff slautghers this amp.
