kkcc, thanks for posting your experience, was very interesting and fairly neutral and well written. i still wait to audition ASG2 somewhere in August, if James is kind enough :-D
otherwise very interesting review and findings.
but when you say ASG2 is a replacement for H200 are you serious? A 650$ replacement for 250$ IEM, you must be kidding mate. Perhaps you meant UPGRADE, not replacement.
Based on what I read about your preference in sound and genre, I think you'd quite like the ASG2. Yes you are right it's an upgrade. Replacement as in replacing the spot of the Fun IEM in my current collection. And I paid much more than $650 for mine.... even it would sound the same as the $550 standard one....
Been listening to some Linken Park and REM just now on the ASG-2 and I wasn't bother by most of those shortcomings I listed and it performed admirably. Only the treble is still a bit too hot. Anyone know how many hrs is need for it to be subdued?
