The Majority of Power amps have both RCA and XLR inputs , with a toggle switch depending upon which you want to use. So you could easily have an anlog pre using the XLR, and a processor or reciever feeding the RCA's . Just have to flip the switch.
Best AV Processor for 2 channel
I am looking at moving to a theatre from my two channel. I have a Linn Kontrol and Linn Klimaxes now and am looking to trade out the Kontrol for an AV Preamp. Is there any processor that will come close to the sound of a Kontrol or other high end 2 channel preamps for stereo listening?
