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.

Charles, Everyone,
Thanks much. As the future owner of 300B again this information really helps the decision of where to begin and to spend wisely. This journey shoul be a lot of fun. Best.
Charles, are we there yet, are we there yet? LOL, you are in a unique position. Almost like the first man to see the dark side of the moon. Having taken the plunge on the Elrogs, and having loved them without reservation since day one, I am as you know ever so curious what you think, especially with respect to the EMLs and Taks. The good think is, I have a set of tubes I could live with forever.
Hi Bill,
My wife just told me that the tube package arrive today. I am out of town but will be back home tomorrow, I do look forward to hearing these unique tubes and comparing them to my other favorites. The Frankenstein has clearly and easily revealed the character of every single 300b I have tried thus far. In that 6 Moons review article I had referenced earlier they use the top-of-the-line Thomas Mayer SET amplifier. Yet their description of the sonic character of the Western Electric was identical to what I heard in my system.
Charles,
