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.

Hi Jordan,
I think your Audion Golden Dreams would be a very tough act to follow. I understand your curiosity regarding the Lampizator 211 amplifiers, there's so much stellar audio choices available to tempt folks these days. I can imagine how much music listening enjoyment you're experiencing.
Charles,
I have about 20 hours on my Elrogs now. How many hours does it take to break in these tubes? I don't want to comment until I'm satisfied I've fully broken them in.
