A brief update on the Mullard Ecc82's I'm running in my WA7tp: with several hours listening today I'm at 20 hours on them and they are indeed improving with break-in! This is for me THE choice for the T1, they have never sounded this good with any tubes I've used-not even close! Incredible layering and spaciousness, enhanced bass that seems to go deeper but it is well-defined. Highs are not harsh at all but not rolled off either, while vocals and mids are gorgeous as usual with the T1's. I got into some jazz today and it was just stunning, percussion is mind blowing (ever heard Ahmad Jamal's Blue Moon album?). I frequently end a listening session with a track from the 192/24 flac download of "Kind of Blue", today it was the entire thing - twice!
