The market departments of the audiophile brands had 50 some years of lavishing snake oil out on the consumers. That does have an effect on how people think unfortunately. I understand that the OP doesnt like surround sound. Lots of people dont and thats ok. What I dont understand is why the OP doesnt use the Marantz as his integrated or pre/power amp combo. Why put out money for a dedicated 2 channel amplification when one can guarentee no sonic advantages over an AVR?
