I've got a strange problem that I thought I'd post here to see if anyone has encountered anything similar. My music system consists of a Krell KAV-300i integrated amplifier driving Legacy Focus speakers. I use this system also as part of a movie system. I take the main L/R pre-outs from my AVR and run them into the "S-3" input, or pre-ins on the Krell. This S-3 input is designed for use with a separate AV processor, and is disconnected from the pre-amp circuitry of the Krell.
I utilized a Sherwood R-945 receiver for years with this setup without issue. I just replaced the Sherwood with, first a Sony STR-DA4300ES, and then a Denon 3808 CI. With this setup, I get a loud, line level popping noise through the speakers driven by the Krell at irregular intervals, generally every 3-7 seconds. The noise sounds to me like some sort of an electrical discharge, but I'm just guessing.
I went through 2 versions of the Sony AVR as well as the Denon before pulling the Krell out of the system. The service guys at Krell have never heard of such a problem, which makes me reluctant to just send the 300i back to them for inspection. Has anyone ever encountered a similar problem, with any amp and pre-amp? Any ideas or suggestions would be appreciated.
