the avr10 is base arcam for 7.1.4 so cant do things like auro3D the marantz can. not sure if an issue also no dts-x pro and such. other main issue woudl be bugs i would do your own due diligence in this regard. there is a whole thread on the "new arcams". Arcam AVR10 Based on these, and my own experience with my Anthem MRX-520 I'd go with the NAD. Anthem's ARC is very good but DIRAC live is better. I also love the idea of the NAD MDC slots for adding functionality to the thing down the road and it already has BluOS built in (if you're part of that ecosystem). Top.
The AVR10 looks likes a good choice to replace my NAD T758 V3 with (which I choose in favor of the AVR390 because bass management was bad on the Arcam AVR390) Dolby Atmos 7.2.2 | KEF R700 | KEF R600c | 4x KEF R300 | Boston Acoustics A25 overheads | Dual SVS PB-2000 | Denon AVR-X4100. This is a review and detailed measurements of the Arcam AVR10 7.2 channel Audio/Video Receiver (AVR). It was purchased by a member and kindly drop shipped to me. AVR10 costs US $2,500. Notes: our company Madrona Digital is a dealer for Harman which owns Arcam so feel free to read any level of.
