I've pick-up a pair of TJ Fullmusic 2a3/SE from local used classified. The previous owner planned to use them for his preamp diy project. Apparently, these tubes had significant followers among diy. But, I was a bit reluctant as they were pricy and TJ had high failure rate for its 300B (according to local tube-maker).
I'm quite happy with my pair of sophia (with u52). Holographic soundstage, smooth, seductive mids, and extension on both end. However, I felt that I kind of miss the texture of vocal and instrument (I felt my system a bit too smooth, and miss that raw nuance of the music). So I decided to pick up that tubes a few days ago. Previous owner said he run about 25hrs. So far, I had about less than 25 hrs. And they do have the texture that I looking for. It still lose a bit of the soundstage of sophia (maybe still need more burn-in), a bit forward in vocal than sophia, but have the texture to die for. To compare with dac, IMO, sophia had that bit that I like from a good implementation of ess chip (soundstage, smoothness), and TJ 2a3/se had that texture from multi-bit dac. Hopefully, these pair will not have that failure issue.
