I have had in my sampling of gear this year, Yamaha rxv1800, v367, v667. Denon Avr-791, 2312ci. Pioneer vsx82, 1020. Harmon Kardon avr, onkyo hr-r557, sr-603, nr609, nr709, nr807, a-8048. All older gear, but gives a general impression of what that company tweaks in its setups, processing. Used the same gear and speakers to be objective. To my ears Onkyo brand receivers sound the best. I tweak each machine to be setup the same. Rz-8 series would push anything you want. My 2cents.
