I have been able to have both the monster 3250 and the 7500 hooked up in my system and to my ears I prefered the sound of the monster by a slim margin. It seemed to me to have a little better bass and just a little more dynamics. I had the monster first and returned it to give the 7500 a try so as to not have to add an amp to power the rear channels. Don't get me wrong the 7500 is a great amp and would be a great addition to any setup I just liked the Monster a little better and with the prices it can be had at it is a steal. The Monster can be also be purchased with a two year warranty from some authorized dealers but the 5yr warranty from the outlaws is also something that one must be considered.
