Ok, looks like I can skip the amp upgrade and invest my hard earned money on something more sensible, you guys are great!! :-) I'm going to order the SVS PB1-ISD tomorrow, PB10 will be here shortly so I hope the PB1 is not going to be on back order or anything. Next thing I need is a pair of heavy-weight stands to secure the M22ti, my 11 months old daughter is starting to walk, those curious little hands are all over the place!

Tom, where did you set the crossover point on your PB1? and which main speakers are you using? :-)
