I own a Pioneer S-DV363 home theater system. According to the service repairman my receiver has a faulty part which will cost 230.00$ to repair. I would rather replace the receiver as I can get a new one for approximately 250,00$. The unit I am considering is the Pioneer VSX- 520-K. The salesman did not Know if it was compatible with the speakers of my S- DV363. Can you advise me on this? Thank you.
