Receiver Advice - repair elite SC 37 or buy new one in the $2,000 - $3,000 range

I have a Pioneer elite SC-37 Receiver running 7.1 Def Tech BP 7004 fronts, with a Def Tech Center and BP 8080 Surrounds and Surround backs with a velodyne sub. The surround back left channel all of a sudden stopped working and I'm wondering if it is worth repairing or not? Anyone know what the possible repair cost could be? I called numerous repair shops but as you might guess that want me to bring it in and I'd rather get an estimate without having to carry that heavy SOB into the store. That is part 1 - an estimate if anyone has had a similar repair?

2 - if i decide to buy a new one, what in the 2-3k range is available these days and will anything be a major step up over the sc 37? i'm primarily into movies, about 90% of use as it is in a dedicated home theater.

Thanks as always for the help and valuable advice everyone!

AFAIK, both surround back channels contain the exact same signal. There aren't any soundtracks with discrete surround back left & surround back right audio. If the surround back left amp bit the dust you can either move the surround back right speaker to the middle of your back wall and just use that, or wire both surround back speakers in series to the surround back right output on your AVR. In either case, rerun the MCACC setup after you've reconfigured your speakers.

If you're just jonesing for a new avr however, you might want to consider upgrading to a receiver with Audyssey XT32 room correction (Denon AVR-X4100w or higher).

Of course, if you get a modern receiver like the 4100 which includes Atmos, you'll be buying more speakers, too....

ah, that is an interesting idea. That wouldn't put too much stress on the one surround back right channel amp? if that is true i really like that solution to tide me over for about 6 months. Was planning on upgrading around then but would like to upgrade my sub first. it is rather old, almost 10 years, and is starting to act up a bit.

Thanks!

yes, when switching the surround back speakers the same channel doesn't work and the SBL speaker works when using it with different channels. When you say that i could wire both to the SBR channel, wouldn't that just make them both on or off? Aren't there scenarios where the SBL would be on and the SBR would not be putting any sound out?

Indeed there are, but not many. Unfortunately, it's the left rear surround amp that's normally used if you configure a receiver for 6.1 (center rear) Check the manual to be certain, though.

Did a little more research and it looks like BD audio tracks can be encoded with discrete SBL & SBR channels, so I stand corrected. Regardless, if you rewire your system into a 6.1 configuration and then run MCACC, your AVR will know that you only have a single SB speaker and it should multiplex the SBL & SBR channel information and direct it to the single surround back speaker.
