Having 2 volume controls would not degrade sound?
So keep volume control on amp constant, and adjust volume on processor?
But, why not the other way around, keep volume control on processor constant and keep processor volume fixed?
In other words:
Could I change the volume on processor, and measure the voltage of the output on the processor so that it matches the voltage output of, say my CD player. Then have processor volume control fixed at that level/voltage, then just vary the volume control on the amp?
(Hope this makes sense)
