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.

Jeff,
Yes, the problem has been discovered and competent people will correct it. George Lenz of tubesusa.com has been very responsive with me and in direct/frequent communication with Elrog, so I'm in good hands. They won't ship the new Elrogs until they've been fully tested at the specific needed parameters. That's fine with me. From this point onward people seeking Elrogs will be asked what amp are they using, this will ensure proper matching. I believe what I have experienced in this situation will help others.

Well, after waiting so long for my Elrog's. The Post Service lost my first pair. George was kind enough to send me another pair last Saturday (I wish I would have waited). I see I won't be able to use them with my Franks.

I hope George (Tubes USA) will exchange them for ones that will not be stressed in our Franks.

I did listen the them for a few hours. They sound very good out of the box, very smooth and refined. Hopefully, with more hours they would surpass the Takatsuki's, as of now I still like the Taks better in my set-up.
Elrog's agreeable approach to finding a workable solution for owners of the Coincident Frankensteins is commendable.

Well you know my high regard for TAK and EML. The Elrog is very good "out of the box" and keeps improving with time. You may ultimately prefer the TAK in your system. In my case the Elrog was even more communicative of musical soul and emotion without sacrificing the good stuff of the other two tubes. For certain time will tell. Elrog just pushed "all" the right buttons in my system.
