Was considering the life of the unit since I’m using external amps for the entire setup and the amps are always on in the yamaha per say. With the Marantz ideally amps would turn off and would only run the Rotel and McIntosh, eventually I will be moving to a storm or trinnov once I lll be the system to the media room av the living room where it is now. To the subs, the 212se pair are amazing and I consider svs and Id brands trash in the aspect of aesthetics.
