Hi I have a Onkyo TXSR806 which I brought 3 years ago, it needs a repair and the shop have offered to give me a new ONKYO TXNR609 free of charge, or repair my old amp, my choice. MY QUESTION IS THIS: When I brought it I did a lot of research and was very happy and still am with my buy. But I'm out of the loop with whats current and best. So I don't know if I'm being offered a GREAT DEAL, or would my old TXSR806 out perform the newer cheaper TXNR609 and should I just get it repaired again? Thanks for your help in advance! Paul.
