I own those old Stax SR40 phones since when I was a child in the late 80s, I'd been using them for a few years for listening to classical music till mid 90s, then put them away. Yesterday I decided to put them back use again, so I connected all the hardware and tested them with some music.
Unfortunately the phones don't seem to be working fine, and I doubt the problem is the amp: the music comes out very low, and the worst thing is that if I pump up the volume to the max the sound gets to a normal level, but it gets really crappy, it seems like the music is frying.
I tried to look around the forum for similar issues on the same Stax model but could not find anything similar. Is there anything that I can do to fix them?
Thanks In advance
