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.

Charles, what you suggest is certainly possible. I think you and I so far are in complete sync with respect to what we hear, and that holds despite the disparity in our musical tastes.

I just can't fathom how the guy who designed the equipment I admire so much, were he sitting in my room doing an A/B with the Elrogs and Psvane Ts, would suggest the difference was subtle. It is not close to subtle, and anyone who says it is needs to have an ear irrigation, my respect for Mr. Blume notwistanding. Something seems amiss to me.

However, if anyone purchases a pair of Elrogs and is not satisfied, I'll be willing to trade them straight up for my moth balled Psvane Ts. Just let me know.
Bill,
Our music taste is different yet the Elrog conveys the essence of these indivual genres wonderfully . Germanboxers has a system of entirely different components and yet his impressions are as enthusiastic as ours. In the end I just acknowledge there will be inevitable differences of opinion.
Has anyone heard or had experience with Elrog 300b tubes failing? I was very interested to get a pair but heard this from one source -cannot confirm it is true or not. Thanks
The reliability problem seems to be fixed about a year now. I own them and have no problems at all.
