Hi Brian my friend owns a pair of modified 2+2s with a Pass x-350 it is a very good match plenty of control in the base and that,s what Acoustats need ( control ) and here the Pass shows that he is the boss this is not a sissy amp i own a Bow Wazoo XL that i like a lot but it is in no way a match for the Pass and i also own Acoustats 1+1s 82db now thats hard to drive my 2 cents
