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.

MK,
Thank you so much for your input. You are a positive influence on the Agon, please keep coming back with your valuable input. We all welcome your knowledgable suggestions. We also all need to encourage folks like yourself and Elrog as a company to seek higher levels of advancement in audio. It is great that a modern tube can best NOS. all the best. Rob
Mk,
How about Wyetech Sapphire monoblocks?
18wpc parallel 300B SET self-biasing conservatively run.
Will your tubes work here? Would love to try 'em!
Hi Fla,
I have read the article in 6moons and the description on the manufacturer's site. Very nice amp with a lot of effort in details (huge capacitors in HV supply, dedicated heater supplies for each output tube, smart solution for changing the gain, switchable output impedances from 2 to 16ohms).
Very gentle operating conditions...30W dissipation per output tube only...So "Globe Mesh Type" 300B can be used. This tubes don't like stress also. This amp was build for ER300B ;-)
For best results You should order a matched Quad.

Best regards, Matthias
Fla,
Based on Matthias's favorable comments you're fine with the standard Elrog ER 300b.
