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.

Markus1299,

Are you using your P10 on all of your components, including the amplifiers?

Dmarkov,

Yes, my entire system is plugged into the P10 and it indicates that I am using 54% of it's capacity.
I received my Elrog replacement tubes and I'm listening to them now. It's funny how much I enjoyed the EML XLS while waiting for the Elrogs. The Elrogs raise the holistic/presence factor from the EML's already high standard. Both are wonderfully dynamic and energetic with lively involvement. The Elrogs are more fluid, organic and provide just a bit more sense of 3 dimensional space, you are there factor. Beautiful natural tone!
As I've said before, it's a move from excellent to the sublime. Time and use will determine reliability and longevity merit. It nails the sound quality portion. George of tubesusa.com has been simply terrific during this period wih his service and support. Thank You.
Charles,
Did they actually construct some special Elrogs to match the Franks, or are these the same basic tubes you had last go-round?
