So, I had a chance to do a bit more listening to the 200s. when i got them, they had the medium tips pre-installed and they seemed to fit me well, even though i always use large tips, whether Comply, Hybrids, silicones, etc.... i'd read that the 200s didn't isolate that well, so i never gave it a second thought..... This morning i put the large tips on, and gave them another listen. Wow!!!! they are getting better and better - with the large tips i can use a shallower insertion without having to give up bass response (they've got plenty to spare!) and can have a giant, well defined headstage and more even timbre and tonality. Now i have even less reason to open up the 100s, if i can wait to hear ericp10s pair at some point down the road.
No question, these are very good, the question remains - how good?. More to follow.
Happy Holidays all.
