I currently have an old Rotel 1066, but am having a problem with the LF channel cutting out intermittently. Not sure if it's the Rotel or my in-wall Canare LV 61S interconnects, but because it's intermittent, it's difficult to isolate. My question is, if it's the Rotel, who makes the best PrePro out there now? I don't need or want an AVR, just a PrePro to select between my Oppo 103 and my turntable and adjust gain. It doesn't need to process video or audio, just a straight wire with gain. Also, anybody have suggestions about how to isolate an intermittent problem like mine?
