Upgrade advice wanted - Replace Sony DA777ES or use as amp?


I have an old Sony DA777ES in a bedroom that's hooked up to two Epos M15s, and a PC and some old game consoles.

Recently, the Sony's digital processing went kaput, so I'm looking for a replacement.

Should I replace it with a new receiver, or buy a preamp/processor and use the Sony as an amp?

Id like to spend no more than $1500, with the ideal closer to $1k.

1k will get you a bunch of used gear.. Adcom 535, 545, amps. b&k pre, belles, sonographe, yamaha natural sound stuff, nad.  These would most be analog rca input, no digital, and no video options, which wood just go to your tv anyways
It seems then that you have a 2 channel system. Does the Sony still work as an line level integrated? If it only works as an amp, I see no reason not to use it that way, and spend your money on the processing side.

What processing do you need?
