They're brand new and I've only put maybe 45 minutes of head time on them.
I will definitely try the high output but I doubt that'll help.
I think once I put my EML rectifier and Sylvanias in they'll sing. That setup will make any pair of cans scream.
My initial impression of the hd700 is dull, lifeless and boring. They don't sound bad persay.
Obviously this is just an initial impression and I'll follow up once I've gotten more time with em
i tried to listen to my dx90 straight out to hd700's on low gain and the 'phones became dull and lifeless, not at all like when i listen from my integrated amp. i haven't tried the dx90's higher gain settings, so i don't know if that would make a difference. anyway, they are supposed to be MUCH easier to drive than hd800's, but that doesn't mean that anything at all will be sufficient.
