After 100 hours of burning I can confirm that I like the WE845 Shuguang better than the 845B, despite the non-consistent construction of WE845 (internal is not as solid and fine built as the 845B, one on my 2 tubes is even weird to look at inside).
So I made another direct comparison by exchanging the tubes and warming them up at least 30 min before listening.
The WE845 definitely brings more flesh, more tri-dimension soundstage, and punch as well (although this is not what I was looking for). The main thing is the midrange much thicker and "material" than the 845B.
I wish Shuguang could be more serious about the construction of these tubes, whether they are imported directly from China or from TAD, the few guys I know from other forums had the same surprise to see the weird internal assembly of those tubes, sometimes even broken.
