Onkyo TXRZ30 9.2-Channel AV Receiver

This is a serious beast of an AVR receiver. I upgraded from an Onkyo TX-SR494 to support 8K, more recent decoders and HDR support. I also wanted the preamp outs so I could drive powered main (L/R) speakers without hacks. The RZ30 runs cooler than the SR494 did and powers up a little quicker too. HDMI-CEC behaviour seems more solid. I have not tried the Dirac room correction yet but I have little doubt that will be great.
All told this has been both a smooth and a satisfying upgrade. I like this AVR a lot.
