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.

AudioNote Quest Silver monos + ER300B = Dreamteam

(Try 8Ohm speakers at the 4Ohm tap...)

Matthias, Were you able to find the operating points for the AudioNote Quest? I was looking on line and could not.
Thanks Matthias; I'll likely give them a try 😀! My speakers are a pretty benign/relatively flat 6 ohm impedance so I'll definitely try the 4 ohm tap.
Do you know how the Elrog 300B will operate with the AN Kit-1? Best, Rob.
Mathias, what about the Audion Golden Dreams? They are parallel single ended triode (PSET) amps. Thanks...and your help is very much apreciated
