On order, new receiver

Just order new anthem mrx 720, picking up this weekend.  Any who are interested I will post my comments after hookup. Can't wait. 
I’ve been thinking about the same model....looking forward to hearing about it.

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.

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. :)
The lexicon is a preamp. I don't need extra amp channels.  I have a bat vk 200 2ch and a b&k 3 ch amp. I will only be using 9 channels.
Eric did u already get this receiver?
Well I did get my new receiver, mrx 720. Spent Saturday hooking up and doing cable management.  Listened to some music and movies.  Overall happy with sound. Tried to do ARC with my Samsung s9,  but microphone is not recognized with phone. Tried ARC again with apple x10 but only the front and center worked, rear kept saying excessive noise, which I know there is no excessive noise because I am the only one home. I have an apple computer, but that software is not available until April.  I have an old lap top I haven't used in a couple of years,  I will try that this weekend. Overall no complaints.  So right now no ARC in use. I set distances and that's all. Sounds much nicer than my old lexicon dc1. Movies the dialog is crystal clear.  I am sure the arc setup will be much nicer. Music sounds great, but nothing to a/b it with.  Using a transparent digital coaxial for blue sound, waiting on a nordost silver shadow, see what that will do. That's it for now. I will update once I get arc working. Pete
Last night I downloaded the anthem calibration tool on my laptop.  I'm running 5 channels,  no sub. Called anthem because I had trouble with the microphone not being detected and also after the USB update on the mrx720 my network became disconnected via network cable. The fix for network is power off and disconnect power cable to mrx, then push main power button 6 times, reconnect power cord, power system on and after a couple minutes network reconnects.  Another thing I did not no was if you are running 5.1 don't connect amp to rear pre outs, you need to use surround outs. This was why the calibration will only work on front 3 channels.  Once changed to surround speakers, everything works flawlessly.  I did upload my first calibration file. Did not get a chance to watch a movie, but I did listen to some music. WOW what a difference.  Everything sounds so much better, imagining is excellent along with bass. I'm very very happy with the performance.  I do lack the knowledge of setting system settings,  but the anthem ARC does the perfect job for people who don't have the knowledge to do there own adjustments.  I will give a review on ht once I time to watch a movie. Anyone considering the anthem,  I personally give it 5 stars. Also thanks for help from Jamie at anthem,  extremely helpful.  April anthem will be releasing the apple version of arc and I was told it will be easier and more friendly adjustments.  Pete
PS: if anyone has any questions,  I will respond to what I have learned so far.
