KLH Model 35 replacement

Hello, I'm a real beginner in terms of home equipment, and I need some advice. I have an old KLD Model 35 deck with KLH Model 6 speakers. The 35 is not working. I took it to a repair shop but he wanted $350 to fix what he said were a number of issues, and I think I'd rather spend that much on a new setup that may last longer into the future. As far as I can tell the speakers are in fine shape, though all their original wiring is frayed, destroyed, or lost. What advice can anyone provide on a suitable, low-cost, similar replacement, on whether or not I should try to re-wire the speakers and connect them to the new system, or whether repairing the old system will be better in the long run. Thanks.
