Did more work today;

Already tried to gorund the amp to the preamp before with no luck. Tried a diff DVR (2 prong), no help.

Hooked up a Marantz SR7005 to the amp via RCA and got buzz. The buzz even whirled a bit, changing pitch, loudness, it was wierd.

Hooked up the speakers to the SR7005 along with everything else; BLISS! smile

Looks like I may be selling the 7700 amp. I hate to, I love it, and it brought great sound to my speakers. But I cant go on with this loop or whatever else is the issue. I will be calling to return the Marantz AV7005 tomorrow frown



At least I have good sound working in my theatre....
