In my case, my 'anti-McIntosh comments' (your words) are exclusively based on Sound Quality (during a demo at a dealer using excellent speakers).
When I mentioned my disappointment with the SQ, the dealer stated - with embarrassment in his voice - that his store did not have better electronics than McIntosh at that time - but he could borrow better electronics from a sister store should I be willing to come back for a second demo.
My experience/opinion is completely outside of your '“audiophile snobbery" comments. If there is a bias, "owner-bias" is very well documented (i.e. owners who favor their product for unfounded reasons).
I am happy for McIntosh owners who are happy with their electronics. Until I hear better sound, I remain disappointed.
