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.

Bill,
I like the Bach example. Quality of life is important and knowing what makes you happy is the foundation. I haven't a single regret for the purchase of anything in my audio system. The joy I experience listening to music is deep and fulfilling, I feel fortunate.
Charles,
You guys have made this thread much more interesting than I expected :-). Keep it coming.

Brownsfan, thank you for the reply. Now Elrog seems to be a worthy replacement for the more expensive 300B tubes out there.
Hi Pani,
I thought you sold your Wavac EC 300b amp because you sought more power for your Tannoys. I recall that you did enjoy that amplifier.
