I have been reading that if the 5308ci breaks down we my have a hard time finding parts. If that is the case and I sell my 5308ci what would you recommend. Let me start by saying that I love this receiver. But if I do sell what would you get. Here are some. Onkyo TX-NR5010, Pioneer SC-68, Marantz SR7007, Denon 4520ci. I have read a lot of things on Pioneer . I am looking hard at Marantz, and Denon. So what do you all think.
