When I first got them at the office, I felt more or less the same way comparing them to my ES7s out of the iPhone. Once I got them home and plugged them into the Duet.. whoah..
Granted, I've never tried the 9s, but I suspect the 10s scale well with good sources and amplification. Now I can't stop listening to them and can't wait to hear them out of a good dedicated amp.
Yeah, paired with a Pico, this might be the ultimate transportable office rig
