Which AVR would you consider high end? For me that would be the AVR-x7200wa, RX-A3070, MRX-1120 and some Euro models such as Arcam's top models.
AVR-x4300H, X6300H, SR7011 etc would be mid range.
If using launch MSRP alone, I consider the bands, < $1500, $1500-$2500 and $2500+.
Yamaha and Denon hit the AVR price/features sweet spot at any tier.
Marantz slightly less so in mid to low tiers.
Anthem not at all.
The best deal can be had when picking up a previous gen AVR on closeout pricing, like the 4300H currently for $800. This may not apply every generation, like when HDMI 1.3/HDCP 2.2 got introduced. So, I have an AVR that's completely satisfactory in audio processing, but, lags on the video side.
