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.

Dracule1,
If it turns out that you like the Elrogs in your DAC then it's money well spent. These tubes are expensive.However operating in a DAC circuit should mean low tube stress and very long life.
Dracule, my thoughts are similar to those of Charles, which is not surprising given that we are talking about the same tube in the same amp. What I would add is that the break in was very subtle. At most, break in gave another 5% of what you had straight out of the box. May your tubes live long and prosper.
Brownsfan I sure do miss Spock Leonard Nimoy one of my favorites. I really felt sad when he passed on many different levels.
I think he would find us audio fools illogical because you cant reach for live sound.
