    I was really hesitant to order this amp due to the power it claims and the price point! Really happy I decided to do it, to be honest. I’m sending my AQ2200 in for repair and needed something to replace it in the meantime. This amp has definitely exceeded my expectations and I cannot tell a difference in power between the two. Just hoping that it lasts as long as the other one that I plan on keeping as a backup once it’s fixed.
