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.

Hello all.

This discussion is just what I am looking for. I want to upgrade my tubes and these two appear to be the best options.

This discussion seems to be about using these tubes in Wavac and Frankenstein amps.

Does anyone have experience using either of these tubes in Cary 211 series amps?

Thanks.

I don't have the Takatsuki's, so this post is possibly off-topic. But I do have the Elrog 300Bs (third production series), and the EML 300B-XLS, so maybe my remarks are of some tangential interest. First observation about the Elrogs: they are dead quiet; second: huge bass (which is not generally a characteristic of 300Bs). There is no denying the XLS's power, however, their effortless handling of transients, and silky midrange. Well... a tough call, both are most excellent valves, and certainly outclass any Russian glass. In my system they drive Tannoy Lockwoods (about 94db), so power is not really the issue. On balance I guess I tip towards the Elrogs for refinement and ease of listening. But if I put on the Wagner... it's got to be XLS.
When I listen to very dynamic big band jazz the EML XLS really deliver the scale, power and size of the band in all of its glory. It really uncovers the full weight and textures of instruments individually and also as a full ensemble. Yet it does justice to smaller scala music as well. I can't wait to get the Elrog tubes and compare them to the EML.
