@sns As I previously mentioned, in checking around the web you’ll mostly find satisfied users of all the boutique 300B tubes. This tells you one of two things, either all the boutique tubes are nice or its all confirmation bias. You may find a particular 300b is preferred for a specific component, but overall they all get high marks.
Agree 100%. In my opinion all of the premium tier 300b tubes are excellent. Invariably some are going to be better matches than others in a particular circuit or amplifier (Even depending upon overall audio system voicing).
I purchased the Takatsuki when first available for the American market (Bought directly from Japan) it’s a superb 300b. I feel the same with regard to the Elrog I once owned.I have no doubts that the Psvane Acme, Linlai, and Current production Western Electric are superb choices.
No one can claim that one is unequivocally better than the others. Too many variables come into play. My 300b SET amplifier sounds brilliant but is a bit hard on the tubes I have learned over the years.
So in my circumstances the exceptionally rugged and durable (And splendid sounding) EML XLS has worked out best long term for “me”. The higher cost upper tier 300b tubes are worth it in a high quality amplifier. You’ll get the most out of a good amp with them onboard.
