Can’t say if the OP
Has found his Nirvana yet, but as a longtime Anthem user I would urge a bit of caution.
the newer Anthems have a great feature set, but the sound in 2 channel may not represent the high price tag.
For example, I would audition the Anthem in 2 Channel mode with a list of your favorite songs and see if the sound is to your expectations.
Too many times AVRs are demoed in DD or another surround mode and in my experience the ss modes can mask the true 2 channel sound character of the internal decoding and amplification.
