Dave, bummer you had so many issues. I received my TRP SE last week. At the 50 hour mark I was wondering if I made a costly mistake going with the TRP, it was sounding bad, two or three nights in the beginning I left the room and let it play, it was rough. 115-120 hours it's calmed down and and I'm enjoying listening to music again. It is still changing the way it sounds at 150 hours. Others on WBF report 300 hours is when it's good to go.
