Have you changed your mind about a brand? Was it you, or them?

I've changed my mind about many things.  Beer for instance.  Now I can really only drink IPAs and dark beers. Lagers?  Phooey.  This is very different than what I drank in my 20s though. 

Same for audio gear. 

So let me ask all of you, are there brands or equipment you've changed your mind about, for better or worse?  And if so, why?  It doesn't have to be a brand, it can be a TYPE or technology.

For instance, I used to love Ti and Be tweeters.  Now usually can't listen to them.

What about you?
My first component system was Fisher, which back in the ’60s I thought was a really top brand.

I’ve been disappointed with Classe for not supporting legacy products when a tuner and an amp were unrepairable.

And I am still sore at Graham Engineering for never sending me an owner’s manual for the Phantom arm, tho I do like the arm.
I'm more a dark beer guy than a lager drinker, but Ma'a, a brewer based in my new home town of Hilo, brews an excellent enough lager to give my lager drinking a new lease on life.  It's good enough to stand comparison to the lagers I drank in Bavaria...though perhaps not as good as the lagers I drank in the Czech Republic.
Ok, being of German descent Lager beer is where its at for myself.
Windhook Lager is just jolly fine too - and of course all brewed to "German Reinheitsgebot" i.e. no 🌽 Mais, rice 🍚 , or any other unspeakable stuff added to replace barley malts. 

As for Audio... B&W is one brand I lost my 'emotional' connection to.
Gone from affordable floorstanders to way-out pricing and still no more tickling my sound bone.
The first Wilson Watt/Puppy I listened to during a 1996 audition in Germany.
I didn't 'connect' then - too hyped up a reproduction - a second higher version number of same construction, at my then home in Pretoria SA... terrible sounding bass performance, bad on my ears, and plain wrong to me. 
Though I till beleave Wilson creates some amazing newer items, though completely unaffordable for my liking AND my purse. 
So... disenchanting as well, overall. Maybe I was never enchanted in real-life, just by circumstances? But yeah, surely tickled by them fantastic reviews.

I bought my first new headphone, after 25 years with Beyerdynamic Dt 990 indestructible headphone that my wife break with the aspirator, 8 years ago, Hifiman He 400 replace them; but they break themselves in 2 parts suddenly after 4 years of using them with care for no reason excess defective design....Paid a 300 hundred bucks at this time for a defective hyper hyped product....It gives me a first lesson.... Some other comes after....For sure i will never buy Hifiman products in the future.... Nor any too hyped new one..... :)

My wife remember that accident because that motivate my obsessive journey in audio audiophile experience for the good 7 years ago....I mange to do that without much money but with success....

My speakers and audio system is so good ( vintage speakers Mission Cyrus and amplifier Sansui AU 7700)now that i dont use any of my 7 headphones even the Stax models.... Good Speakers rightfully embed trash them all on all counts....

My best....

A remark: Contrary to the Hifiman experience, the Mission experience and the Sansui experience were so good i bought another model for each one of these brand with complete satisfaction....
I used to have a lot of respect for lower end B&W speakers; bought my dad some in the 1990s and they sounded nice with NAD gear.

On my recent outings to audition bookshelves, all the B&W speakers were over-bright to the point of aggressive harshness. I understand this was a choice on their part, perhaps?f
