Yesterday, while watching a movie, at a particularly loud passage, I heard what can best be described as high frequency crackling, and some sort of weird "phaziness."
It didn't stop.
I thought I blew out one of my speakers, and immediately suspected my front right height since it was recently repaired. I was somewhat perplexed at this thought, since I was watching the movie at -10db from reference (shouldn't be an issue). I walked to the front of the room, and, sure enough, the sound was coming from that speaker...but unlike last time, no "magic blue smoke" smell.
I went to the equipment closet and disconnected the front heights from the back of the amp.
Uh oh. The cracking and odd swishy sound was still there. I turned off the movie, and went into setup and did some channel sweeps. My surround L and surround R channels had this strange effect, while my surround BACK L & R were fine. I reconnected my front heights, and found that my front height L was *fine* and the R was similarly screwed like the surround L and R.
Okay. This is strange. I took down the front height R, and substituted it for my front R. The speaker is fine. It isn't blown.
The surrounds are on a completely different amp, so I probably don't have an amp issue, but I proceeded to try to track it down. After a whole bunch of combinations, I convinced myself that the amp itself is fine, but the AVR seems to be the problem. It is outputting this noise to the front R height, and to the L & R surround.
So, I did a full system reset. No love. it's still doing it. I tried to do a firmware update, but there isn't a newer one available. So, here are some questions, which I *think* (and hope) are relevant to this thread.
I've got what seems to be a broken Denon x4000. I upgraded to this AVR from a Yamaha-RXA3000 because I wanted Audyssey xt32. I have to investigate if it is worth getting the x4000 repaired (cost to repair, vs value on the resale market or value to me in the future).
But now I need a replacement for the x4000. The Yamaha (which now runs the family room) isn't a suitable replacement because it doesn't have pre-outs for the front height channels (and I've come to learn that I prefer DIRAC on the entire front sound-stage, at the expense of the surround rears being corrected).
I *don't* think I want to bite off ATMOS just yet. I think another year or so will probably do (so, AVRs that are coming out now might be a better buy on the used market next year).
Can anyone suggest an AVR which meets the minimum criteria?
1) 9 channel capable, including front height
2) pre-outs for all channels
3) 3 (Hah!) hdmi inputs
4) 2 hdmi outputs (mirroring is fine, no need for a real 2nd zone)
5) of course, nothing so old as to not be able to decode today's modern codecs [minus the object based ones]
6) I'm looking for "as cheap as possible" (including, and maybe preferring used) because it will either be replaced by the x4000 (assuming I bother to get it fixed) soon, or it will be replaced with something ATMOS ready next year or so.
I think those of us that are using the 88a all fall into this sort of new category. We really want pre-pros since we don't want to pay for the amps, and we really don't want to pay for room correction either...but that sort of thing doesn't really exist anymore.
