YMMV - Don
The key point for most people is the first one - Passive bi-amping as implemented in AVRs is not worth the effort, and provides no significant gain.
There is no YMMV about it, nobody gets an audible benefit out of passive biamping.
Passive biamping only benefits people who sell amplifiers.
As applied to AVRs, it is a lame attempt to add another feature to the blurb sheet.
