What makes Telefunken tubes sound better?


I've reached the point in sampling 12AU7 tubes below $100 per tube where I'm having to buy tube crates to keep the pairs I've sampled. I've tried NOS and new, but out of all I end up back with Telefunkens as having the least distortion and fastest transient response. Yet the Telefunken internals are not the best materials/quality; NOS Mullard CV4003 or the new Gold Lions have higher build quality for materials and precision.

Are there links somewhere that talk to what is different for the internal design/construction of a Telefunken tube? I'd like to support newer tube manufacturers based on educated consumerism, and hope that we can get someone to replace Telefunken at an affordable cost before NOS stock is no longer an option.

Let me just add that if the same percentage of Americans moved to Germany it would amount to 2.4 million Americans moving there.
I don't think you'll find anyone emulating the materials or manufacturing practices of Telefunken today. Totally different eras.

Today's manufacturers use computers, modern materials and manufacturing techniques to optimize the sound of their tubes while Telefunken used materials and manufacturing techniques that are no longer feasible.
Schubert, The US is far more inclusive than Germany. We are not divided into the super rich and the poor. America is still the land of opportunity, currently less opportunity than usual because of the policies of our current government, but we will get through this and come back strong. We fear no one and take great pride in all the good we have done and continue to do at home and around the world. Germany does not come close to our accomplishments in this area.

Angela Merkel said that Germany is not a nation of immigrants and doesn't want to be one. That doesn't sound too inclusive to me.

Sorry for going off topic but I can't stand anti-American BS.
Schubert, Germany is a prosperous and free country due to American generosity and ideals of trying to make the world a better place for everyone.

Germany has no such generosity or ideals but only thinks of enriching itself while America provides its security.

America could have let Stalin have Germany and you would be working in a labor camp, you would not have money to spend on audio gear and there would be no German culture. As a matter of fact, you would probably have been worked to death by now. How about those facts?

Your Telefunken tubes are good though.
What do you want to know about tubes Bojack? I'm no expert but I know a little.
I am sure that Germany is a nice place to live, I would love to have the opportunity to live there myself, and there is no doubt the US is facing huge problems; and yet there are 618,227 people who were born in Germany living in the US according to the Pew Research Center and 192,676 people born in Germany have immigrated to the US since 1986 according to the US Department of Homeland Security.

Schubert, why do you live here instead of Germany since you dislike the US so much?
