One comment about amps to use with PSB speakers..... I also use PSB speakers with two 10" subs. Before getting the PSB speakers I got a NAD integrated amp thinking it would be an upgrade to the amp I was using with my former Klipsch Reference speakers. I was disappointed. Sounded like someone put a blanket over the speakers.
Then I went back to the dealer who sold me the NAD amp and auditioned it with some PSB speakers. What a difference! Seems that NAD and PSB are or were sister companies. So if you decide to change amps don't rule out NAD. Sure, they don't stack up to all the rave reviews of others but the do have synergy with PSB. Some models have a second pre out so connecting subs is easier.
