Which tubes is better. Siemens or Telefunken?

call Kevin Deal at Upscale Audio for relevant tube recommendations. He's on Audiogon.

Just get a good DAC and forget about patches.
Just my .02.

Brian,
I have the same unit replaced the philips with some 60's Amperex,gold pins-sound superb-warmer overall and rounder bass-I also have a pair of Raytheon 7308's which are better than the Philips but not as good as the Amperex.
Kevin tends only to sell to previous customers especially NOS 6922's.
There's an excellent FAQ/Description of NOS tubes somewhere on the Web,can't remember where now perhaps a search might throw it up-it details the best of NOS tubes.
I'm in the UK,I believe buying NOS tubes here is about the only aspect of hi-fi that's cheaper than the US.
I've messed about with this unit a bit,I think whatever quality NOS tubes you use will be an improvement but I think also you have to be realistic about the improvement it will make considering the cost of the X-10D.
Good luck.

I've used Siemens and Telefunken, but for different applications. Both were excellent. The Siemens was ECC88. I spent quite a bit on these tubes, but the improvement was by far one of the most cost effective improvements I've made in the system in a long time.

The NOS FAQ section Ben Campbell is likely referring to can be found at Audioasylum.com..go to tubes section and from the upper left hand corner you'll get to info on NOS 6922 and variants.

JMAN that is the very one thanks...
Ben

Both tubes are fanstantic tubes, just different sounding. The Siemens are transparent, extremely detailed, airy, with a tight bass. The Telefunkens are warm, rich, transparent, naturally detailed, with a softer, more rounded bass. In the right system, either would be beautiful.

fletchj is absolutely right in my opinion and rch10 at IBM probably has never heard what tubes can do. Cheers,

A good NOS tube will be very quiet also.They are perfect for phono stages.
I have 2 Telefunken 12AX7's in my Rogue 99 phono and the noise floor is almost as quiet as my old Lehmann Black Cube... which is saying alot!!

What's better- Chocolate or Vanilla ?? Siemens and Telefunkens are two of the finest NOS tube brands ever produced. You must determine exactly what characteristics you are after in a tube and then find the tube(s) to fill that specific need. If your component uses more than 1 pr. of tubes in the output stage- also consider a combination of different tube brands. Think of it as adding various spices to the sauce- A great sauce typically doesn't just contain salt and pepper.

I just took out the 2 Philips SQ E80CC’s in the front of my Jadis Orch reference and rolled to the Siemens E80CC.
The Philips blows away any and every AU, ever made, including all Tele/Siemens, ampereex./philips,
But the Siemens blew away the Philips ,,,go figure,,I;d say ’Siemens tubes all, are top dogs, /King of all tubes.
= expenisve, but worth it.
I am trying to get all E288CC’s/Siemens(288 is the big boys in 6922's) in my Cayin cd17, bought 2 with full print = authentic Siemens, NOS, pair $150/baragin froma California seller. Will buy his other 2 when i have cash,,,now i will also buy NOS/or strong 12AX7’s for my jadis Defy, takes a quad, = don’t have to match, will pay no more than say,,,$60/ea.
<<<<will consider Dyanco which are Siemens.
<<want long plates.
<<<am telling you Siemens are the best tubes in the world, No hype, no snakeoil.
Those guys who made those tubes back in the 60’s/70’s really madea King of all preamp tubes.
<<<Love Philips/Amperex, but sadly, i have to dump that entire collection for all 100% Siemens,,I am not going to collect tubes any longer.
Siemens are simply magical,,My 2nd choice would be Teles.
But considering what someone wrote about, Siemens are my 1st and only choice, Detailed, airy.
<<<am telling you, i was really surprised at the siemens E80CC’s blowing out the highly regarded Philips SQ E80CC’s.
<<< have to sell all my E80ccs and get 4 more Siemens for my upcomming purchase of the Cayin SC6 preamp,,has,,FOUR!!!! AU sectiosn = 4 Siemens E80CC’s,,,,,,don’t get no better.
<<< will run 2 Siemens E288CC’s in one channel of the cayin 17 MARK1 and 2 Philips PCC88/1970 NOS ($22 each/ebay) and see how the Siemens respond.
No not at all worried about extra current in the 288’s.
cayin has hefty trans. Unit built likea tank.

mozartfan, Dynaco used mostly Tele's for small signal tubes. Fisher used a lot to.
Just because one brand sounds good in one spot on one particular device has no bearing on what it might do on another device. A lot has to do with the operating parameters of that particular device.
That's why it's nice to have a varied collection of tube types and brands. Even good used tubes are good for rolling, when you find the tone you like than look for NOS if you desire.
mozartfan, I'm interested in your Amperex tubes.

Wow! time marches on...

This is an 18 year old thread.

Normally it depends on each particular model, year of production and even a factory where those German tubes made. I enjoyed Telefunken, but never tried Siemens, i’ve heard that both are top quality in general. It is more important what is better for YOU

I’m about to purchase some NOS Siemens 6922 tubes (a trio) for a Conrad Johnson Classic 120. I have been using NOS Amperex 6922 tubes, which are fantastic. But I want to have several NOS back up sets of tubes, so I am going to give the Siemens a go. 
 

I’ll report back on how they compare to the Amperex 6922, but this won’t be until sometime in January.
