Thanks. My equipment rack is on the left wall, the power amp sits between the front speakers. So, the in wall interconnects go from the rack to a wall plate in the middle of the screen wall, then regular ICs to the power amp from the wall plate. Here are a couple of photos. I need to make and install the raised panel wainscoting and get some carpet in there. It'll be nice when I'm done:
Last night the LF channel cut out again while listening to a CD. Disconnecting the IC at the Rotel and plugging it back in a couple of times brought it back. Then I switched the ICs at the Rotel, and after a while, the RF channel cut out. Fiddling with it brought it back again. So, The ICs are good, as well as everything downstream. I had previously replaced the ICs for the front channels going from the Oppo to the Rotel, and the problem persisted, so I think everything upstream is okay, too. I put a call in to Rotel, we'll see how good their CS is. The unit is quite low hours, if it can't be fixed, I'm done with Rotel. The new 1572 sounds problematic.
Update: It seems the RCA plug for the LF channel on the Rotel is the culprit, in that the connection is positional. Sometimes, when playing with the IC, which itself is solid, you can get full volume, partial volume, or no volume. I moved the Analog Out for the LF channel from the Oppo to the CB1 input on the Rotel, and the IC out of the Rotel to the corresponding CB1 Pre Out . Seems to work fine. If it does, I'll leave well enough alone. This all makes sense, as the RCA plugs on the back plate are the only parts that are physically stressed. We'll see how it goes.
