RE Russound. Since the primary programming resides in the amplifier, you have the ability via the I device to control whatever is programmed there. With my system at home, I turn on the ap, select whatever zone I wish, whatever source I wish, adjust volume, review meta data from onboard frs tuner or I device or streaming device, and have it in language the customer understands (kitchen vs. zone 1) Using external parasound and multi channel amplification, my KEF uni-q drivers sound great.
