I have a CDA-7930. It's my favorite receiver of the ones that I have owned. My question is this: will it be worth getting it "refurbished"? It was still working well on the receiver section, and all crossovers/functions worked fine, but the CD section was getting kinda bitchy. It would almost never read a burned disc, and it was having lots of errors on pressed discs. If I were to send it to Chris Lewis, do you think all this would be solved? Secondly, since it is an Ai-Net model, can I add an auxiliary input to use my OmniFi unit?
