Hi All, this is my first post here!
I've inherited my Dad's old L1290s (which I loved back in the day). They still sound pretty great, but I'm questioning the high frequencies. They seem a little "harsher" than I remember them being, from 30 years ago! I do remember they were quite bright when they were new, though.
What I'm noticing, is that on recordings with any kind of hyped, exaggerated highs, the tweeter can almost sound distorted...not quite distorted, but it's like I can hear it ringing out, on its own, as if is not integrated with other drivers, or is too loud or something.
