The thing that I hate the most (that is other than the heat given off by my amps) is the fxxxing sharp, scalpel-like corners on the ART amp. I can't tell you how many times I've cut my leg on the amp since I'm in cramped quarters
i can see how that would have happened.
i had the CJ M140LP monoblock amps (same family of amps) here for a few months and i was able to avoid actual blood letting; but moving them around did require one to pay close attention to their lethal corners......if my room was small it would only have been a matter of time before i would have been skewered.
i'm trying to think about what piece of gear has caused me headaches or something i can't seem to dial in correctly; and i cannot think of any in my recent memory. most of my arms and tunrtables i've had in my room in the last few years have been set up by the tt builder, arm distributor or the arm builder; my amps and preamps have worked flawlessly, and even my tape decks have all worked as they should.
the room changes from a year or so ago all proceeded properly too.
i guess i've been lucky in audio/music reproduction terms.
knock on wood.
OTOH i am getting older, business could be better, the world is going to hell, and my sports teams are pathetic.......
