4musica44107,
I have not found a tube I like better in the Wavelength than WE.
I have also tried
Sophia RP - edges too soft.
I am thinking of trying the Elrog when available.
a sleeper tube that is good in my Wavelength is Shuguang 300BS for about $200.Make sure it's the 300BS.It looks like a mesh plate with a black coating.I got mine 4 years ago and I don't know if they are still available.
Has tighter edges and closer to stage than Treasure 300B.
The Treasure has a little more bass and farther from stage
YMMV
