On order, new receiver

We are displaying Anthem dealers, we just setup a MRX 720 at a clients home, three Kef THX Ci 3160 THX inwalls, Paradigm Defiance 12 inch sub, Epson LS 10500 laser projector and the MRX just rocked.

The difference between no room correction and the ARC engaged was mindblowing, very obvious how much better the system sounded.

One cool function of ARC is the ability to see the corrected response vs the native room's uncorrected reponse.

The ARC room correction is really somthing. The difference in clarity was very noticable as you remove the peaks the ability to hear smaller details becomes much clearer.

Dweller, 
It has hdmi 2.0a, hdcp 2.2 and does 11.2, 4 channel atmos. I'm getting for the arc. It does have 7 channel amp, but you can add your own amps to get 11.2.  Everyone seems to rave about the arc and how easy it is to use.  I've heard dirac is better, but a lot more $$$ and from what I read you need to have some degree of experience to setup. Arc is pretty easy to use. I am getting the mrx 720 for 2250.00 at dealer.  My setup will only allow for front, center, rear and 4 atmos.  Can't do sides do to room configuration.  This should be a great upgrade compared to my lexicon dc-1, being over 20 yrs old. I will only use I'll internal amps for atmos, still need to purchase them. Not sure what I will get.

The 720 is worth it even for 5.1. The larger power supply give you more watts / channel, especially if you don't use a couple of them. :)
