norcuron Posted May 19, 2022 Share Posted May 19, 2022 Hi, I have a Marantz AV7704 and Sunfire Signature 400 x 7 Amp powering a Gen 1 RF-7 5.1 setup. I am hearing some intermittent static in my left rear surround and have a feeling my amp is finally dying. I am seeking recommendations for a new amp. I definitely run this amp very hard sometimes and am wondering how many watts I need in a replacement. I use if for home theater and when I demo my system to others I demo everything from Enter Sandman to the Centipede song from Knife Party. Thank You all for your recommendations Quote Link to comment Share on other sites More sharing options...

M_Klipsches Posted October 8, 2022 Share Posted October 8, 2022 I just ran across this thread, and wanted to chime in; better late than never I suppose. I just had a Sunfire Cinema Grand 400 - Seven with similar issues. It was perfectly, refurbished by Greg at Nelion Audio. So if you still have this amp, it’d likely be worth checking him out. https://nelionaudio.com I can completely recommend his work. 2 Quote Link to comment Share on other sites More sharing options...
