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.

If I were Israel Blume, I'd offer a Coincident Frankenstein Premium package. Elrog 300b and the Mullard GZ37 rectifier tube. It wouldn't be cheap nor ultra expensive either(within reach of a lot of people). With a proper efficient speaker it would keep many folks off the money draining High End merry go round. People could simply sit back and indulge in their music library with sheer joy.

Charles,
Your a bit confused about my 300B future. I am going to purchase the Coincident Franks and Pre with the 101 as soon as my new house is ready; I will have my own dedicated 18x20x9 listening room. My wife is going to build the AN-Kit One a bit after settling-in. I'm keeping the Dynamo in my office. A while back I sold my Cary 300B SEI. I will be selling my Cary V12 and Primaluna Dialogue One. I was thanking you, Brownsfan and others about your take on the Various 300B tube which will save me $$$$ in the long term. Your experience will allow me to go directly to Elrog, EML, and/or Tatkasuki and not spend on lower level product. I did like the Black Treasure in the Cary SEI. Looking forward to talking more about your Elrog experience as you get more time on them. Congratulations! Best.
Also, I'm positive the Tektons will match beautifully with any of the discussed amps; the AN Kit my wife builds will be paired with either the larger Lore, or perhaps we go all in on a newer Tekton model. As for my room it's likely time to say good-bye to my Infinity Prelude Composition (about 15 yrs. old) and step-up to Coincident, Tannoy, Daedalus speakers if they match ok. I' going to hit some shows, travel to NYC, LA, etc., hopefully this will be end game for Amp, Pre and Speakers.
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!
