Don't you love how fast and informative this company is?

Jgonino, since you got your impressions done professionally, you won't be disappointed with the sound at all. This thing sounds amazing... I think it'll only get better with a good amp.
The comfort of the customs are setting in now. I can almost forget that they are there. I actually slept with them on last night - tugged on the cable a few times and it's fine.
It's so easy to drive these things. I would estimate that they are 20-30% louder than the SF5, which are already super loud.
