[QUOTE="Sarel.wagner, post: 1119082, member: 25509"] During the coof period I rebuild my HP1's. They were a bit tattered, headband was crumbling and lots of other small niggly things bothered me. See this entry at the IEEE Hall of Fame: [URL='https://spectrum.ieee.org/the-consumer-electronics-hall-of-fame-yamaha-hp1-headphones']Yamaha HP1 hall of fame IEEE[/URL] [LIST] [*]Type: orthodynamic headphone [*]Drive units: 55mm [*]Impedance: 150Ω [*]Frequency Response: 20Hz to 20kHz [*]Input: 3000mW (nominal), 10000mW (max) [*]Maximum SPL: [*]Distortion: 0.3% [*]Cord length: [*]Weight: 290g [*]Price: $200 [*]Year: 1976 [/LIST] Since I got the IFI Zen DAC V2, this was time to really start using the HP1. Still need to sort the cable as the original is a bit stiff and not nice no more. I did modify the cups with better damping and they sound wonderful as always. I bought these new in 1982 after saving for a long time, cannot remember what I paid for them any more.
