Tele CCa Vs, Siemens CCa

In response to the poster's question, if the rest of the signal chain is very clean, I prefer siemens grey plate cca. If things are not "quite there", however, the telefunken cca's are a little softer, and i often find them preferable. Several times i have noticed that the telefunkens sounded better when equipment was new, but the siemens sounded best when the same equipment was finally broken in. Not too scientific, just my observations.

Listen friend, the Siemens is superior from top to botton all day long!!

And twice on Sunday!!

I have the blue pointed head Tele CCa (without the <> )
I think it is a special order from Siemens.
They are unbelievably better (organic, weight, tonality) than the Semens CCa (definition, clarity, no bass & weight)that comes 2nd (but not close) & miles away of the Tele ECC88 (thick, homogenise bass, no detail & definition).
Now bear in mind that these 3 tubes are by far better than :
ITT (polite & laidback), Siemens ECC88 (complete but low-fi), EAT ECC88 Diamond (-a Tesla in tuxedo- dirty HF, etched).
Unfortunatelly I didn't have the original Tele CCa to comment.
I test them in my active battery pre-pre.

Siemans CCa better mids better stage better bass airer highs much better.

My list of premium ECC88 6DJ8 tubes I had an opportunity to test:

"The best ever ECC88 / E88CC / 6DJ8 / 6922" is CCa Siemens gray shield

Than: Philips Miniwatt E188CC 7308 two stars

Next one is:CCa Siemens silver shield

I didn't listen Telefunken CCa, but I tested E88CC 6922 Siemens and E88CC Telefunken 6922 diamond bottom and Siemens gray shield is much better than both of them.

Enjoy the music!
