I have a Marantz Cinema 60 and normally I use HT bypass on my preamp for music. I tried the Cinema 60 for the first time with music (2ch) the other day as a preamp (Mc462 as amp) with no room correction. It honestly seemed fine. I did feel like the soundstage was an hair less but not positive.the channel separation on my 60 is not as good as the AV10.
If I walked out of the room and back in I am not sure I could pass a blind test. It has made me wonder if an AV10 could work as an all in one unit for me. I like to manage my subs and have been thinking about doing this differently lately.
so I think if you are not super pick an AVR could work. A few times I bought other brands instead of Marantz and always regretted it and went back to Marantz.
the “Marantz” sound is in the DAC filter. It starts rolling off at 12k and is down 0.5db at 15k and 2.5db at 20k. On the higher end models you can turn the filter off and choose “filter #2” which is totally flat.
Measurements of the AV10 here.
