Here's the deal, when it comes to an AVR you are best served to stick to the BIG Brands! To me, today, this means Yamaha or Marantz/Denon, and that's it!
In days past, Pioneer and Onkyo may have been worth considering.
The fact is simple, ONLY the big brands have the engineering resources needed to produce a reliable AVR! Modern AVRs are incredibly complex electronic devices, and you better have the engineering resources to make them work properly.
When you go to a boutique brand for an AVR, understand that these small competitors simply do not have the engineering resources needed to guarantee a rock solid AVR experience.
At the end of the day, $ is no object, it is the hassle and headache of a boutique brand that is more important than the bottom line $.
Now, if we are talking about 2 channel stereo and less complex analog pre-amps, that is a whole different discussion vs. the AVR discussion.
