theres been so much i have blocked out of memory haha. bring things home, hook them up and then have to figure out if i can leave them at savers at 1:00am and run like hell..
ah Im a big zenith collector, but yes there 70s stuff sucked, tho it was well made..
carver i think its the av-130-160 burns resistors, due to them being too small due to design, smell like cat pee when they heat up and cook the board, like millions of cats peed in one receiver, went through 3 of them as i liked the sound, but all of them had this issue..
I love nad stuff, but ive ran into gear from them where the deisigner forgot to add some numbers or something and put a part in not up to the job. some of their 90s av units were like that, I had one that actually launched a capacitor through the top of it, like through the case. it was like something out of a cartoon.
. there new stuff isnt like this though.
bose 501s. super cool looking. sounding like something being played through a wet sock, that was taped by a microcasette recorder by a drunk person. with weird tweeter sounds flying all over ;/ older 201s too. there are some boses i like too so im not one of those bose is evil people.
ah what else... a whole lot of 80s gear. almost assume off the bat when i find it its either going to stop working in a week, sound like crap or both. tho there are some great units from the 80s as well..
nothing is uniform by brand tho. one denon i heard was one of the worst, and my denon pma is one of the best i have.
and some newer teac stuff.. looks fancy but meh sound. thats all i can think of currently..
