Hello.... I have a Denon avr 3600, which has a pre outs and also a tape2 loop switch. I also have a Denon AVR 5800 that I would like to connect together. Hopefully someone is familiar with these early generation AVRs and can tell me how to hook both of them together. The Denon AVR 5800 is a flagship in its year, but does not have a tape2 loop/monitor option (which is very important to me)...where-as the Denon AVR 3600, being a lesser model....does. I am an avid analogue fan with lots of vintage equipment, but also want to tie in my home theater. Thanks in advance for your help
