Elrog 300B vs Takatsuki 300B tubes


Has anyone heard the Elrog 300B tubes ? I read an article which mentioned that the Elrog 300B delivers 15% less power than a traditional 300B tubes. Can anyone confirm that it is audible ?

I am choosing between Elrog and Takatsuki 300B tubes. I would prefer the Elrog because it is cheaper and supposedly wonderful but if it really sounds less powerful then I have to rethink.

Swampwalker,
I have read good things about that amplifier, what speaker are you using with them?
Oh I see you have the Merlins. How is the LD SET compared to your Wavac MD 300b?
Charles, I'm looking forward to your take on the Elrog myself. Your input in the past helped me purchase my Franks and 300b tubes. I'm very happy with my purchases. Thank You!
Hi Joe(Snopro,
I am very happy that worked out so well for you. I know just because I love the SET experience doesn't mean they'll please everyone else.
Charles,
Charles, I'm very happy with what I hear, but again, I have no experience with the top tier tubes. My frame of reference is Psvane T's and TII's. You are the guy who will shortly be in a position to rank all of the top notch tubes, at least as they perform in the Franks.
