1. German made Siemens: Excellent resolution and stage positioning, however the sound is not as solid
and thick as England made tube. If your system lacks in resolution, then this Siemens made will be your first
choice.

resolution is not as good as Siemens. Suitable for system with delicate sound.

mid range, with full sound and good resolution. They are more tends to neutral style.
4. Telefunken ,TFK: Nobody could hardly ignore Telefunken if they were enthusiasts of tubes! It definitely
is the highest rank among various brands. With impeccable sound, good quality, harmonious sound, longevity,
it has been recognized as the best tubes ever (though some one might do not agree with that). Furthermore,
Telefunken has stopped produce tubes for a while, and folks are earger to seize one, that makes it incredibly
expensive, especially for those Audio tubule, such as E88CC, CCa, ECC82, ECC83...
