Thanks jjss49, I ran the H390 continuously for a week when I first received it. Afterwards, I did hear a substantial improvement. It probably has about 400 hours on it now. Maybe I should let it run for another week. I really wanted to love this amp.
I still have the H200 so this past weekend I did a back-to-back comparison with the H390. The 390 is crisp, clean, and refined sounding. In comparison, the H200 sounds like there's a thin veil is over the music but the bass and drums are front and center. The music seems to have more body.
