@sns Do you find that even reliable budget 300b tubes (gold lions, linlai black plates) sound as good as ’premium’/more expensive 300b tubes? WE, Elrog, TAK, ELS etc?
I can’t speak for @sns but based on my listening experiences the answer is no. You can achieve pretty good and certainly what I’d consider solid or respectable sound quality.
As discussed above in this thread, the premium tier of 300b tubes are plain and simple better built and unquestionably better sounding. I would also point out that with certain brands you will get longer tube lifespan.
