I'm always seeing all manner of audio stuff on Chinese sites but have never taken a punt because there's just no information available. Members of my family in Hong Kong are into hi-fi but it's more money than I'd ever spend. I'd still be interested to see exactly how Chinese higher end components perform, rather than the usual Western suspects.
Whilst Western brands are prized, hi-fi being no different, there's a thriving home audio culture there and in mainland China at all price levels, where you'll see no western or Japanese brands at all, it's all proudly Chinese. It'd be good to see some "off-brand" Chinese products all the way to luxury devices tested, I'm sure there's plenty of undiscovered gems. It'd take a far keener eye than mine to see which ones are worth trying though.
As for this AVR thing, I'm in the UK and apart from the few friends/family who share my passion or I've pushed and setup with home cinema/hi-fi systems, it isn't common to see AVR's or even proper two channel any more. I'm just guessing but from what I've seen they're both on the decline in favour of sound bars and all in one music systems. Maybe a smart speaker or an all in one bookshelf system is the best you'll get. It's probably telling that if you buy a telly you're not going to be upsold an AVR, or a system in a box, it's always a sound bar.
Smaller houses and just how close neighbours are have probably influenced that. I mean this is large detached bungalow but I'm still wary of cranking my system in the evening, at least with the subs on, because I know for a fact the neighbours will hear it. When I'm in the Highlands I push it more, but I still can't crank it as much as I'd like. I'm not pissing off a Highland cow. Or its owner. Convenience/consideration for cows has won out.
