thats what i've heard at least from hifiman and others, its supposed to be like an easier to drive HE-6. someone else told me that its not as good though, a reputable person.
i know its not as pretty as HE-6, the He-6 looks much nicer with the piano black finish, but if its easier to drive and i can get rid of speaker amp, it would be really nice to have. i can get some money back and don't have to worry about my old speaker amp for using it.
It's different, voiced between the 560 and 6, so it is a bit warmer than the HE-6 I reckon but SQ should be up there or very close.
