Advice needed Please, To Fix Or Not To Fix?


My AV receiver needs repairs totalling 317 bucks. This includes the 60 bucks diagnostic fee and tax. The repair man tells me it needs a new output board, multiple caps are leaking, and there is signal loss all over. He will also thoroughly clean it up inside. A complete referbish as he puts it. It's a Integra DTR 5.4 and I have had it for years. I always thought it sounded good. I have it paired with a combo of Energy and Yamaha speakers, sub is Energy too. What do you guys think? Worth fixing or should I get a new piece? I really miss not having 5.1 and want the sound back but I do not want to spend too much on a new piece. What would I have to spend new or used to at least match this piece? Thanks in advance to any one who responds.
P.S. The price quoted for repair sounds pretty fair, but I admit to not having too many things fixed so I don't really know.

Marty, thanks for all that info. I realized I have two extra speakers ( Ireplaced them with Yamaha mini monitors for the left and right front speakers. My rear or surround speakers are small Energy. The spares are the same. What do you suggest? I was thinking of two sets of left and right fronts. Thanks again.
The best place to start IMHO - if the room is big enough - front l&r plus side l&r plus rear l&r, along with center and sub(s). That's a straight 7.1 (or 7.2 if you have 2 subs) on the back of the Onkyo AVR.
Marty, my room is pretty small. I will experiment with the extra speakers once I get something. Thanks.
Marty, I hope you see this. I can get either the Onkyo HT RC 360 or 460 for around 300 bucks. Do you have an opinion on these? Anyone else seeing this I would appreciate any input. Thanks.
