babadono Posted May 9, 2019 Share Posted May 9, 2019 So I had a 7 channel power Amp Monster, a Sherbourn PA7-350, that took a dump for the second time. I acquired this from Emotiva when they took over Sherbourn. On this second failure they politely refuse to fix, but gave me full price credit to buy something else from them. I have a Marantz 7007 AVR that is now running all 7 channels but man it runs out of gas with the RF-7 IIs and RC-64II. My idea/question is should I get a 3 channel power amp to run the front 3 and let the Marantz power the surrounds? Or should I be looking for another 7 channel amp. Surrounds are in-ceiling speakers, I think CDT-5800-C-IIs Quote Link to comment Share on other sites More sharing options...
Shiva Posted May 9, 2019 Share Posted May 9, 2019 My vote, a 3 channel amp for the front 3, let the receiver power the rest. What failed on the amp the first time? 1 Quote Link to comment Share on other sites More sharing options...
babadono Posted May 9, 2019 Author Share Posted May 9, 2019 Its a long story but let's just say with insufficient cooling one of the channels smoked. 1 Quote Link to comment Share on other sites More sharing options...
Pete H Posted May 9, 2019 Share Posted May 9, 2019 I would agree that a 3 channel and the receiver can easily handle the requirements of the surround channels, unless you're running 7's all around LOL. My 7's performed with a higher wattage receiver, but though they are pretty efficient, my experience has been that they like a lot of good watts behind them to perform their best. Mine are performing well with my Emotiva XPA 5, but I've run them with Carvers and QSC etc..and they haven't been too finicky, and anything that's been rated 200 WPC has done well. 1 Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted May 9, 2019 Share Posted May 9, 2019 If the receiver isn't powering the front 3 it will have plenty in the tank to power the sides and rears especially considering the fact that they're in ceilings. Quote Link to comment Share on other sites More sharing options...
Emile Posted May 9, 2019 Share Posted May 9, 2019 How about @ClaudeJ1's mini amps? Not sure what you have "up front," but Claude seems very pleased with these cheap amps for his Khorns (I bought one a month ago, but have not tried it yet ) Quote Link to comment Share on other sites More sharing options...
Schu Posted May 9, 2019 Share Posted May 9, 2019 Three channel or three seps. Quote Link to comment Share on other sites More sharing options...

DTO Posted May 10, 2019 Share Posted May 10, 2019 The Emotiva xpa-3 for $200 with the credit seams logical to me. It’s on my short list of what upgrade to try next..... Quote Link to comment Share on other sites More sharing options...

For $200, and my experience with Emotiva, I would have to agree with this, unless of course you have the time to build something, but why not try this, small outlay and if you don't love it, sell it and build something at that time.

willland Posted May 10, 2019 Share Posted May 10, 2019 Three channel amp is a great way to go. My first experience with amps was a B&K Reference 4430(200x3) and I added it to my existing Onkyo TX-SR705 to drive my LCR. Huge noticeable difference across the board.
