If, like me, you love your Emotiva A-100, consider the A-800 - four clean 35 Wpc (That's @ 8 Ohms - 50 Wpc @ 4 Ohms - all eight channels driven!) class A/B stereo amps that can be driven by one stereo source - or eight channels driven independently. It's less than the sale-priced Dayton class D amp, too. I must admit - that Dayton amp has some great spec's and features!
