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.

I just left Charles home and spent a couple of hours with him listening to his new Elrogs. All I can say is that they are fantastic. I notice a lot more bass weight and foundation yet they are very open and clear on top. I think they are smoother less grainy if thats possible. Wonderful wonderful tube.
Jeff,
Thanks for your comments and it was fun having you drop by my home today. Our systems are very different in terms of components and room acoustics, yet both reproduce music beautifully in their unique way. Both systems emphasize the natural sound approach.

Rob,
Yes I thought the AN Kit amplifier instead of the Frankenstein. Given your plans, you and your wife will have a home filled with wonderful sound in multiple rooms. Great plan!
Charles,
Rob,
As you read above, Jeff heard my system today. He knows my system intimately and thought as highly of the Takatsuki and EML XLS as I do. My advice if you can swing it, get the Elrogs for your Frankenstein. Start at the top with this combination, there'll be no looking back or second guessing.
Charles,
Charles, I plan to do just that. I feel like the kid in school looking over your shoulder for good notes. I really trust your ears, Brownsfan, Rebbi, Jwm, too, amongst others. All your musical values are very similar. Looking forward to your continuing comments regarding all things audio.
Oh, forgot to mention, I got a High Wycombe 378 in anticipation of the Franks purchase.
