Not ruling anybody out: Anthem just seems to check a few more boxes than anybody else right now. (For my wants and needs.)
Would love to see Emotiva evolve into something a little more. Would love to see Monolith establish itself outside of the Monoprice moniker, too. Love my Outlaw products right now, but not interested in their processors. Intrigued by ATI, but again... they aren't hitting for me right now.
Anthem in the closest to what I want at a price I might be willing to spend.
This is a crazy hobby that in many cases, defy logic! There are many people (me included) would go from avr to >$3K prepro and then back to <1K AVR yet many more would have to try the other direction..
I guess I know why, as I have done exactly that, but am still curious to know other's reasons to start such a move (and the specific model you are looking at), especially someone so well informed as you are..
My best guess is that you want to try Anthem ARC? You apparently tried Audyssey, and don't like the results, yet with the App you could change the target curve and save multiples of them to try, and if you are a follower of the recommendations to limit the range to below the room transition frequency that you are really only dealing with the effects for the 15 - 300 Hz range at the most. Regarding the target curves, we both know that does not mean the results will follow too closely, in fact most likely not, not for the whole range anyway, but no RC systems can. If it was sold as a standalone system, I would like to try it too regardless, but only because I enjoy playing with those things, not for better SQ at all.
The AVM60 is relatively cheap now for a boutique AV product, but it is almost 4 years old, and like the popular brands, it is still virtually an AVR with the power amps ripped out, add more balance connections, and that's it. It has the same mid range DAC that your SR6012 (iirc) has, and that's really disappointing. Overall I see no indications that it would offer sound quality advantage (not even theoretically, never mind audible) over the SR6012. To me, for 3K, there are much better choices, except if you really want to have AARC. Again, not trying to discourage anyone to go the prepro route, just wondering about the reasons for the move, and to the specific "upgrade path" choice.
