I believe my GE 12AU7A tube are on their last leg which I thought are rather new since the unit I bought was a demo with light use. I have been noticing static in the right channel but thought it was the running washing machine or dish washer. But after swopping to the Jan 5814A two days ago, the soundstage snapped into focus and there's much more detail and ambience. I can't wait to get the Mullards and GE BP 5814A triple micas. I know for a fact that my MIT S3's are a bottle neck in my system and hope to find something that is neutral.
