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.

I have about 20 hours on my Elrogs now. How many hours does it take to break in these tubes? I don't want to comment until I'm satisfied I've fully broken them in.

Dracule1,
In my case the Elrogs were very good straight out of the box( and just continued to improve). I'd say broken in by 40 to 50 hours. I use them in a power amplifier and you have them in a DAC, not sure if that is a factor.

Charles1dad, thanks. I think the Elrogs in GG DAC is run at 1/10th power compared to amp application. So it may matter. I'll report when I have about 50 hrs on them.

Dracule1,
If it turns out that you like the Elrogs in your DAC then it's money well spent. These tubes are expensive.However operating in a DAC circuit should mean low tube stress and very long life.
