This message is in response to Daryl on Mar 3. Please be aware that when recievers show that A-B selection , that doesn't mean that there are two descrete amps built in!! It's the same amp in series, Re: stable at 8ohms on A+B or 4 ohms on A or B, so just parallel those two pair of 8ohmers, same result and seperate V/C's will work descretely. I answer calls about this all day, and it is the most common misconception.
P.S. Niles make an awsome 2 ch amp that is stable at 2.66ohms(3pr.of 8ohm spks)100w RMS
Peace!!!
