Hi,\nI am currently running a 5.1(2 subs).2 home theatre setup in my living room. The Speakers are Monitor Audio Silver 6 front left and right, Monitor Audio Silver Center, Monitor Audio Bronze FX for side surrounds, two SVS Prime Elevation for Atmos and two SVS SB4000 subwoofers. The AVR is a Marantz SR5010 which operates as a processor. I am using Emotiva XPA5 to power all ear level speakers and Emotive Basx 8 powering two atmos channel. I wanted to change my AVR so I can add more channels and to improve the performance.\nNeed feedback on whether I should buy cheaper Denon AVC-X3700H \/ X4700H and use Pre outs or go for Anthem AVM70 which is double the price and has more channels. I would be immediately adding two more atmos speakers and by upgrading would be able to have two separate subwoofer channels. The long term objective is to have a dedicated home theatre room with more speakers and not having to change the processor frequently. Also would there be an improved performance with regards to audio by buying Anthem AV70? I have read interesting reviews about Anthem products. But Denon is a larger brand and I feel has better support. Please help with your valuable feedback.
