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 agree the difference between good digital and analog is small today. The difference between single ended and anything else is still huge.
Jeff,
Yes it has unfolded that way for me. I'd choose digital source with tube electronics rather than analog source with solid state electronics in a forced to choose hypothetical situation. Obviously some would prefer the analog and SS option.
Charles, I was just giving an illustration. Even I can move between a good digital and analog rig. However I do not agree that the difference between good analog and good digital is small. The difference is still significant IMO but because they are different sounding one can prefer one over the other or enjoy both.

And yes, the difference between SET and non-SET though is too fundamental. Before the wavac I used to have Naim amplifiers and I loved them. It will be interesting now to bring in a Naim amp into the system and listen. If I do not end up liking it (highly unlikely) I will accept that I have been silently baptised :-)
