got the 2020 NR1711 last 13-Jan

all I could say is despite its mid-height design and 50W into 8ohms power, my MA Bronze 5 floorstanders are still busog... now I could attest to the musicality of the Marantz (I could hear sonic differences with my past 3 Onkyos (RZ-NR-RZ, models in these successions) and I do like the Marantz to match better with my MA Bronze)
with its native 7ch amplification on movies (DD+Atmos, THD Atmos & DTS:X), it's not underpowered for its 50W 8ohms 2ch specs. I could set it with the proper volume and still gets the same loudness that I want and when I need it. with my past 3 Onkyos, I need to raise their center channel volume to max in order to compensate the dialogues to mix with other channels. but with this NR1711, yes I still find the need to raise it, but I'm already good upto +4 only.
all are still under manual configurations with an all flat-EQ settings per channel. I am yet to check what results it would give me when I run it with Audyssey + set the speakers/channels with an individual EQ +- tuning
