Thanks to the generosity of a friend, I will soon have the opportunity to hear the TG334 and compare it to the AS-2 and H-200. Now, I don't really expect the H-200 to compete (not get pushed out of the room), but I do expect the AS-2 to go a few rounds. I will know soon enough.
I should add, upon listening further today, I do think the H-200 has better instrument separation than the W4. The H-200's notes are thicker than fuller than the W4 or UE900 I want to make clear that I'm not claiming that the H-200 is at the top of the heap of top tier universals (I still hold to what I stated several years ago that there is no king, but many in the royal family), but I don't consider the H-200 a mid-tier. I think it's the least costly top tier you can purchase right now (base on original MSRP).
