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.

The Elrogs in my amplifier are a smashing success. This solidifies my decision to keep these amplifiers the rest of my life. A premium 300b tube in an excellent designed /implemented amplifier just hit the right spot for my needs. Its has been 6 years of beautiful contentment listening to music. At some point I may replace the original Coincident power cords, That's about it. Elrog,Takatsuki or EML XLS are all worth their cost in a good 300b amplifier. Elrog leads this stellar group of tubes for my taste.

JWM, Your comments remind me of the episode where Spock's father was suffering the Vulcan equivalent of Alzheimer's. He began to cry during performance of a string quartet. I have teared up a few times during a live concert, but me system, good as it may be, has never moved me to tears. However, having moved away from Indy, where live music is good and plentiful, to Tennessee, where the opportunities are somewhat sparse, has made my investment in a good system quite logical.
I was courageous enough to put the Takatsuki 300B on Lampi briefly.

Well, the difference from Psvane WE101D 1:1 replica was very subtle if any.

I guess I am really missing Elrog 300B's. They were the most resolving tubes on Lampizator.

Maybe after I settle down with my system, I will buy another pair and see if the issue has been fixed.
I've about 34 hours on the Elrog on my Lampi. Sorry to say I'm quite disappointed with the sound. Initially, I had great hopes. When I first plugged them in, I heard buttery smooth sound with accurate timbre. However, it was not as transparent, dynamic, tight in the bass, or extended in the highs as the Psavane 101D or the TJ Full Music 300B SE. Even with break in, the overall sound has not changed. The music feels slow with the Elrogs, and they are the least revealing of the tubes I have. Seems like the harmonics are somehow truncated. Not sure how to explain this given all the positive reviews they've received here. I'm wondering if my tubes are either defective or needs more break in.
Dracule1,
Just goes to show that no product ever gets complete unanimous positive opinions/impressions. Variables and individual ears won't allow it to be. Sorry they didn't work out for you as they have for most of us posting here. I know I've raved about them, that being my honest experience with Elrog.
