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, I did get your email and responded.  Did you not receive it?  Things are going reasonably well here, but I am doing everything I can to get lost in the hills.  Yesterday's hike was 14.4 miles with 3700 ft elevation gain.  Four hikes altogether in the last week. Paradise.   Not getting much listening time in.  2-3 hours a week at best.  I've been following the fuse discussion, and want to hear your thoughts on black vs red, especially in the CSL.  I still have a stock fuse in mine, so this could be a big step forward.  Keep me posted and let me know if I need to resend the PM.
Hi Bill,
I'm very glad that you are doing so well and indulging in your  hiking passion 😊
No  I didn't get your reply email, I am very interested in your in your thoughts on the two speakers. Bill the SR fuses are something quite special. The many positive comments about them are legit. If you only want to try just one,  put it in the CSL. The Red is excellent but the Black is a step above. They're terrific tweaks for the CSL.
Charles, 
Bill,
With the kind of hiking schedule you're following you must really be whipping yourself into seriously good physical fitness. 
Keep it up! 
Charles, I resent my reply to your PM.  The physical conditioning is coming along, but I'm still not where I want to be.  If I can continue hitting it hard, another couple months and I should be there.
I'm following the fuse thread.  I will probably order a black for the CSL in a week or so.  
Bill,
I don't think that you will regret that purchase. Let me know what you think of it.
Charles,
