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.

Bhchung, I also purchased my tubes through Trueaudiophile, and am awaiting instructions about the return process. I would of course prefer to work through the vendor, but if that is not possible I am willing to deal directly with Elrog. Matthais, how should I proceed?
Hi Matthais,
Same question as Brownsfan here. What do I expect from here? Elrog already has my pair and warranty information.
Hoping for a favorable outcome for all of us Involved. I will let people know of my ongoing experience and progress with my replacement Elrog tubes. This site is a valuable communication source. I feel committed to sharing the good news, and the not so good news when necessary.
Hello Bhchung,

Please excuse the delay in processing the warranty replacement!

It's summer and some of our employees are or were on vacation ... And Gary (Trueaudiophile) is a special case too.
So please, Brownsfan and Bhchung, send me a PM including the serials of the tubes, the type of the amplifier and an address, so I can solve any problems (if exist) personally on monday and ship the replacements as soon as possible.

Regards, Matthias
Is Trueaudiophile an authorized USA Elrog dealer? Is there any concern purchasing Elrog tubes from them?
