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, very sorry to hear that your replacements did not work out.  Mine are still OK, but I am getting very little listening time in these days.  Less now than when I was working.   I suspect that you have drawn the right conclusion.  In the event my replacement tubes fail prematurely, I will probably also go the EML route.

Wow, I'm really sorry to hear that one of your Elrogs has gone bad. It sounds like a repeat performance of what happened to me. 

Perhaps there is some hope on the horizon in that a "new batch" should be to George any day now..... Well I hope anyday now since shipment was to be made two weeks ago. He told me that these were supposed to be even better than the batch from which mine and perhaps yours came from. 

Since yours are within the one year warranty period they will undoubtedly be replaced with some others. I guess you can choose to use them and roll the dice once again or just resell them "as new".  

How do the Taks compare to the EMLs?  

Hang my in there my friend,

Well, I  willingly acknowledge The risk with this different type of 300b variant and proceeded with both eyes fully open. Other Frankenstein owners may have a better outcome with a newer batch of Elrogs, tough to say.  It's such an exceptionally good sounding tube in my amplifier that I wanted so badly for it to be reliable long term. I informed George(tubesusa) he'll follow up with me. These are very expensive tubes and they have to offer long term durability to make the high cost worthwhile,

Hi Scifi,
Takatsuki vs EML XLS,
I really enjoy and cherished both of them over a 3 year period. This is such a true example of individual taste and probably system synergy as well. I listen to the EML XLS more often, it has a "bit" more dynamic authority and scale and is organic and communicates emotion effectively. The Takatsuki is very organic, a "bit" lighter in presentation and very refine in character, maybe a "bit" sweeter. Nitpicking aside both are true reference standard 300b tubes and simply excellent sounding in my system

I suspect most 300b aficionados  might prefer the Takatsuki say 55 to 45 from a sample size group of 100 (pure speculation I admit). I give a modest edge to the EML XLS for its added punch and open large scale sound in my system. As I have implied, you couldn't possibly go wrong with either tube. They both have proven track records of reliability, I can attest to that.
