Just wanted to add my recent observation. I pulled out an old Line conditioner and connected the Marantz Sa-14 TRL and I must say this changed things significantly.
This is an old Transformer type conditioner that buzzes in a seperate room away from the listening area but boy o boy this thing doubled by soundstage lifting the imaging off the speakers and creating a surround sound effect. I am over joyed!
TRL family Holiday
I am running full balance output by the way.
