Time for a new a/v receiver could use some input!


I have an Arcam avr400 which is HDMI 1.4 and need a HDMI 2.0 4K receiver.
I'm using a 5.1 set up, so I looked at Arcam but I'm not happy with problems of handshake
So I decided to get another brand.

I'm down to either the Anthem MRX720 or the Marantz SR7013 
just want to stay around $2,500 its 5.1 but I like the power the Arcam has.
Not sure if they are equal in power ratings but I think they are both powerful enough.

The Marantz has all the gadgets you can think of,  but I'm looking for good sound,
 and a lot of people say that the Anthem sounds better, any thoughts?
Thank you

I got the Anthem mrx720 two days ago, in a few days I'll do the arc room correction. So far I'm extremely happy with the sound.
I noticed the dialog is clearer than before, I use a JL audio F113 subwoofer, 
I never heard my sub as tight and powerful as this, that's a welcome improvement.
Still messing with it for the moment, I'll post about the room correction later. 
I take nothing away from the Arcam av400 sounds great, loved it, its just a little warmer than the Anthem and my speakers really loved the Anthem.
Did room correction arc, music sounds more detailed dialog improved, bass was trimmed, brightness was tamed and other improvements.
The sound is clear and a little bright which got better after arc and also you can adjust the treble .
I love the clean, clear, powerful sound.
It seems that my speakers and sub came to life with the Anthem mrx720.
I’m very happy with my choice.
My best advice is pick a receiver or amp that’s going to improve the sound of your speakers.
Thanks to all for your input.
I forgot to mention, after the arc the surround sound improved dramatically, watching a movie now has very good separations that's also a big improvement.
I doubt the Anthem is broken in yet and that some of the brightness you’re currently hearing may subside a bit over time.  Congrats on a great AVR and glad you like what you’re hearing. 
soix,  after arc the brightness was gone and you're right its only been running for a few days but I do love the sound of music and surround sound in movies, very happy with my choice.
Thank you
