To Those Who Want To Take A Chance On A Great Discontinued Product, The Monster Power Amps Are Really A Great Amp. Designed By Richard Marsh And Damian Martin Of Spectral . I Have Three Of These Beasts And They Do Have Plenty Of Clean Power. Monster Has Discontinued Them So A Used One Is A Gamble. They Can Be Had For About Five To Eight Hundred On Ebay. The Emotiva Amps Should Also Be Considered And Are Well Made. The Cost Benefits To Go To Much More Expensive Amps Are Not Worth It In A Home Theatre Situation. In A Two Channel System It All Revolves Around Speakers And Source Material And To A Lesser Degree Amp And Preamp. The Monster Mpa 2250 Amp And 3250 Amp Are 250 Watts X2 Or 3 Channel Into 8 Olms. They Almost Double Their Output To 4 Olms. Good Luck!
