A buddy of mine just gave me these amps and I'm debating on using them with my receiver as a prepro setup. My setup now. I am most concerned about quality with music, it is used 50/50 music/Theater. A Marantz sr-5005 4 infinity SM-225 towers 1 cc-3 Infinity center I velodyne ULD-18 Sub. The Marantz sounds great as is, But i have these amps sitting here so if i can use them then why not, What is considered a better amp the carvers or the adcom. Both are similar rated in power but the adcom is 2 times as big/heavy. What do you guys think, use them on the front or are they overkill, Also if i use them on the fronts and leave the rest on the amp how will the volume scale, Will the gains be equal?
