Heard several loudspeakers in a local hifi shop and chose the Quad. For the HC preprocessor there wasn't much choice available at Emotiva price point. For the amplifier I was leaning toward a Yamaha from the P-S series (http://www.yamahaproaudio.com/global/en/products/poweramps/p...), Crown happened to be more easily available. This one and the Crown have regulated fans. The Yamaha has less distortion and a security cover to lock volume knobs settings..
