To repair, rebuild, or toss?

You don’t have to spend $10,000. 
There are excellent amps that can be had under $5,000 in example Coda No.8 or Simaudio 330a on a used market. 
Since your speakers have powered woofers you can try a Class A amp like Pass XA30.8 or XA25. They show up on used market. There’s also Parasound. 

@amplifier11,

Trash the Rotel. Get a pair of Schiit Tyr mono amps $1599 each and a Schiit Kara F preamp $799. 😎

I’m not exactly a fan of Rotel, but to be fair the RB-1080 was a perfectly decent amp. Wish the same could be said about your tech though:

The rebuild option entails a visual inspection and replacement of parts that look like they need to be replaced.

That’s got to be the most ridiculous thing heard on Audiogon the entire week... And heavens know that’s a high bar 😂😂🤣

For reference, a real rebuild involves at minimum replacing all electrolytic capacitors with quality name-brand ones, thoroughly verify all factory reference values per service manual and investigating / resolving any discrepancies, inspecting, testing and replacing any components found defective or off-tolerance, and finally performing a listening test.

Oh, and if you’re serious about tossing it, I’ll gladly take it off your hands and restore it to its former glory. I’ll pay for freight!

Depending on what the $600 gets you.  V-Caps, Audio Note non-magnetic resistors?  If those parts are going in then upgrade the unit.  But if it is only installing basic parts brands then no.  We upgrade audio components old and new every day with fantastic results.  Usually much better than what you can purchase as new gear.  Most gear does not have the parts I mentioned inside.  Those who recommend trashing the Rotel have never had anything upgraded with these parts so they have no idea what the sound improvement is.

Happy Listening
