Should I repair Stax DA-80 or just buy new amp?

My Stax DA-80 is getting a little "long in the tooth" - and needs repair at this point. It is a great sounding amp and, while not very high power, sounds great with my Dunlavy SC-IV speakers (with Levinson preamp). But before I spend a few hundred dollars to bring it back up to spec, I thought maybe the money is better spent towards a new amp. Any opinions out there?
