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.

Easy Tomcy6---what Shubert means about inclusiveness, about pride vs fear, relates to their workforce and how young tradesmen and women are taken under training early to be included in the tradition of apprentice, journeyman and master levels of craftsmanship. They are then free to take great pride, as they are bound to their trades. Here, there is an accent on competition and on a self-sponsored rise through expensive education and worry about keeping a job.
And as for sharp divisions between rich and poor--that would not be so prevalent in socialist Germany as it is here, where survival of the fittest shapes our social strata into an ever-widening gulf between the rich and poor.
Brownsfan, if only there were some good jobs by which the poor could rise into the middle class. After our recent financial collapse (due to criminal activities of the 1%), millions of young people with four-year degrees are living back at home. All is not well because of many variables, but in our system, there will always be winners and losers, there will always be, has always been, that bell curve, with at least 20% on the near slope--and rising. That's why our safety nets were created in the first place--there was a need at that time to keep the elderly out of poverty. We can all knock welfare for the undeserving poor, but don't go after SS. I've worked hard and have been proud to take care of those who took care of me. That's what makes a great society.
