OK, she's singing now, and I have alotttttt of mods/upgrades to make in my entire system.
I want 1st off to thank whoever mentioned that the AU section tubes is the biggest gain for pre amp section, NOt the AX section, he is correct, when i swapped out the AU's for E80CC's, the sound fq resolution increased DRAMATICALLY, Like Night to bright sunshine.
The AX section, I am not hearing much a dif twix, Siemesb $$$$$$$ tubes vs any old AX (except NOT cheap chinese and russian AX's which are both worthless trash).
All NOS tubes made in the late 50's, 60's are ALL EQUAL IMHO, = Do not drink the snakeoil about Siemens. Sure they area miniscle better, possibly,,I am in a long testing period of AX;s.
At the end of the testing, in about 4 months,, it is my belief my theory of ALL NOS AX;'s are EQUAL,,will prove true.
The real deal ina AU/AX pre section is the critical AU's. as someone here , maybe in this thread, mentioned is the CRITICAL tube in the Jadis Defy7.
= no need to spend $$$$$$$ in the AX section, any old NOS, RCA/Amperex, Tele, Siemens/Philosp, Syvania, etc etc,,will work just fine..
My purpose of this post is to take some of the snakeoil out the sellers market in *Holy grail* AX tubes. Its all bunk, snakeoil.
The true Holy Grail is the Crwon Jewel of all AU's, the E80CC.
I have Siemens and Philips SQ.
The Siemens givea miniscule edge over the Philips = Equal.
ou can see and hear my stereo in action
@3:30 is a shot of the incredible
~~~SUPER TUBE~~~~
The E80CC.
Tungstom, Philips, Tele, Siemens, = Equal.
AX's NOS = Equal, save your cash.
