I really liked the YH-1000. It has locks so that once you determine the right size you can lock them in place. And the YH-1000 sounds really, really good. I wish I could find a pair again.
The YH-100 sounds like poop to me in stock form. But once modded they kick serious tail!
I did not try modding the original frame however. I just went straight for the woody cups. So I'm not possitive how they'll respond to damping them correctly in the stock housing, but my gut reaction is probably very well.
