I have a Int 250 which I used initially with Magnepan 3.7 and rel subs which sounded great. i then went to Wilson Sasha 2 which for me had a more detailed presence and better imaging. The pass has plenty of power and both speakers had/have great imaging depth and did/do a great disappearing act. I haven't had the opportunity to compare with something else in my home but i am pleased with how it sounds... You didn't give a budget but if you are looking to spend under 10k then I would go with the maggies with two subs (assuming you have the room)
