I have several amps but one blows away anything I've ever owned or auditioned. The Mcintosh Ma6550 is unbelievable in its bass... you don't need a subwoofer with this amp at all. I have the bass turned down almost all the way when I listen to music otherwise it will blow you out of the room. If you have doubts, try one out if you can find one.
Did you ever buy too much bass?
I talk a lot about bass and integration of subwoofers in a system and I realized that I need to hear more about the experiences auidphiles have when they go buy speakers and put them in a room. Did you look at specs? Did you audition in the home? Did you end up with too little or too much bass compared to what you were expecting??
