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.

I'd choose digital source with tube electronics rather than analog source with solid state electronics in a forced to choose hypothetical situation

Pani,
We are all different , my digital/analog comparison was strictly a personal
observation and nothing more. I certainly respect that you have had a
different experience and that's to be expected as we are all individuals with
our own taste and preferences. I am sure there are a number of listeners
who would share your point of view in that there is more of a gap between
digital and analog than I appreciate, that's just the way it goes. I am curious
to see how your Naim amplifier experience vs your Wavac turns out. It
should be fun.
Charles,
Question for all the single ended fans:
What do you think of solid state single ended amps, like the Pass Aleph J2 ?

I think it should be interesting considering that it removes the "signature" of any particular tube and its output transformer and also delivers healthy 30 watts. The important question though is, how engaging does it sound. Anyone ?
