I have an update on the startup pop problem I've been having with my Integra 80.2 / Proceed AMP5 combination. I have them connected with balanced cables.
To recap, I get loud pop through all channels when the 80.2 finished starting up, you hear a relay click, and then a loud pop through the speakers. This is not an amp startup, starting and stopping the amp doesn't create pops. Also, for many audio modes, when you end the setup menu, and then exit you also get a pop.
Today I was finally able to track down another amp (an old receiver) to test the 80.2 with another amp. Here are the results of today's tests.
1) Hooked up an old receiver to the RCA outs for L and R. No pops, dead silent
2) Hooked up my amp with the RCA (was using balanced) and no pops, dead silent
3) Found a neighbor with some pro gear. Hooked it up to my amp via balanced inputs. No pops
Evidently the 80.2 lets something out of the balanced outputs that my Proceed amp doesn't like. I now have it connected with the unbalanced inputs and I have no pops. But this kind of sucks because I specifically chose the 80.2 over the 40.2 to get the balanced connections.
I've searched the web extensively and haven't found any posts on amps popping over balanced but not unbalanced.
With my old setup I had balanced connections for right center and left but not the surrounds ( the Proceed AVP didn't have balanced for the surrounds). No pops.
Anyone ever experience this or hear of it?
The dealer has offered to refund my purchase but I don't know what else I'd buy. Should I switch to a 40.2 and get the difference back in cash? He will sell me an Anthem at cost for my trouble but it's a lot more money.
