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?
Agree on the beer.  My biggest disappointment was with the Hyperion Sound, the maker of my wonderful HPS-938 speakers. They had speaker of the year for 8 years in the row and speaker of the decade awards from Absolute Sound, not to mention they had orders for 6 months, after 2004 California show.  After that they never advertised, had no dealership base and ended up in bankruptcy.  Now I have speakers with exotic drivers and no support.
Well, that's not a good example of a brand you changed your mind about.  That's just a brand that didn't succeed.
Sorry I wasn't clear, I was actually trying to focus on audio related brands. :)
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.
