Talk to me about headphones for listening to classic rock (Beatles, Dylan, The Who, etc.) on vinyl. Equipment I'm working with: Technics SL-1200 mk2 turntable Crappy turntable amp that I'm willing to update I'll be plugging the headphones into a Sony receiver (don't know the model off-hand) My budget is less than $1,000 for the headphones and an amp. More than willing to go to the used market. Thanks in advance!
