Hi All. I posted a similar thread over at the Speaker forum but thought I'd run it by the British crowd also. I have recently picked up a pair of W70's. They sound very harsh in the midrange. I recapped them a couple days ago with Russian PIO caps and have been listening to them off and on for a few days. I'm waiting for them to smooth out but it's not happening. I received good advice from my earlier thread but would like to know if any W70 owners would comment on their experience with W70. Are they known to be harsh because all the reviews I read said smooth and very tube friendly. My W70's are from 1967 .
