My problem is that they sound terrible on this preamp. The sound great on my A/V receiver. Does anyone know the output rating of the headphone input? I can't decide on a new headphone without knowing whether I should buy a 32 ohm or higher headphone. My owner's manual doesn't list the spec but I thought I saw it in print some where before. I had a pair Yamaha YH-1's before and they were just right. If I new the specs of the YAmaha YH-1 I'd have my answer.
