Most overrated audio manufacturers?

Burmester

+1Syntax,Burmester, very disappointing sound quality given their
reputation and praise. It was very hifi and not natural at all.

another: Krell

I have heard Zu, Wilson, and a bank of speakers from Focal and each of these manufacturers are what I call 0.5 to 0.33 brands. That is, they are mid-level competitive against competitors at 1/2 to 1/3 their cost. So... a 4K Focal speaker tends to compete well against $1500 - $2000 speakers but is way over-priced . These three brands are very overrated.

Any time I read and advertisement or read about a product that starts with the word" Reference" I know it is bull%$##@
