Heard about this Krell power amp, and how superb the bass response is. I heard a ksa-100, but I'd like to know if there's any drawbacks such as the power outlet amperage, and will it be best to use it on a separate line. I have an air conditioner line rated at 125v- 20 amp, and another separate line at 125v- 30 amp. I've always wanted to purchase this one to go with my other power amp.
