Which tubes is better. Siemens or Telefunken?

JMAN that is the very one thanks...

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.
