300B tube recommendation for SET amp?

Unfortunately, Dogpile, the old, 1970s and earlier, WE300Bs are still the clear winners. I have not tried the 2005 production yet, but the 1995 and 96 production was sadly inferior. I also have yet to try the recent KRs. Of the remainder I found the TJs and Sophias okay.

My experience with the 300Bs is limited in recent years to using them in my Reimyo PAT777 amp. I initially heard the amp with 1960s WE 300Bs, but when I got mine it had new production 1990s WEs. Later I managed to get some 1960s WE and found them incomparably better than what I initially had. I have a pair of TJ 300B mesh plates which I have also tried. I actually preferred the initial 1990s WEs better. I once tried the KR 300Bs versus the TJs in another 300B amp and did not like them.

I know that older WEs cost lots of money, but nevertheless, they are superior in my amp in my opinion.
