Hello everyone have been lurking for sometime and thinking if this would work. Have searched this site but couldn.t or didn't understand the answer. Here we go I have a Denon Avr 3200 and a old PRE Amp Denon POA 1500 is there any way of hooking the POA 1500 to the AVR? If so would this cause any damage? Thank you for all those that respond. Thanks; Gerd
