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.

Tubesnstats,

I've tried many 300bs but not the original/vintage Western Electric (just too expensive to fool with). I did try the reissue Western Electric but it wasn't impressive in my amplifier. As much as I enjoyed the superb Takatsuki I must say that the Elrog surpassed it in my system. The EML XLS and Takatsuki battle tit for tat as both have many virtues. I don't know how much stress your preamplifier places on the 300b compar
ed to  power amplifier duties as required  in my system.

If the reliability issue is truly solved then the Elrog is one of the
finest tubes ever produced IMHO.

 Like others my go to has been the bulletproof EML and previous to that I did use the Sofia RP, they sounded great like others have reported one can fail prematurely and leave you with a chalange finding a match.

I see the Elrog’s are still for sale, curiously has anyone revisited the Elrog 300b and has the reliability issues been sorted out?
@ianderson  I have had new Elrogs, purchased April 2018, in my amplifier running almost daily with no issues. Under new ownership, the QC issues seem to have been ironed out.
