More a fan of Carver's amps. Having had the CT-17 pre amp tuner, I found to have good sound, just harder to operate in it having very small buttons and hard to see the writing on what button does what. I have two Carver amps, the Cube and the CB-15. They are not my primary amps now, but relundant to sell them, simply because the still sound great. IMO Bob Carver is a true audio hero, and his products sound great and even have that I am proud to own factor.
