6922 tube

I have a Cayin CD17 Mark1, takes 2 6922 unbalanced (which i run in) and 2 balanced(which i never will use), So I hada   tube flipping business that went sour = lost $$$$,,anyway,, started buying all sorts, A-Z 6922/6dj8,7dg8, ecc88, cc88, etc etc, 188's, 288's, etc etc, I;'ve heard nearly every variety/lab of this variant. 
= all sounded nearly identical..
Now maby in your Acoustic reserach a  6922 can be diciphered from others,,but in my cayin CD17, all sound nearly identical. 
So I figured, <<must be the circuitry = not so sensitive as per tube typology>> , long story short,, one of the 288's, were bad, amperex, like $125 each,,so a  friend lent me a  pair of russian military Gold Aero,,,pulg them in,,, wow, my system went sour., after all my countless mods, with super high tech parts, were made ~~null and VOID~~~,,all over a  pair of 6922 russian Gold Aero military tubes,, He says they are actually not 6922;'s, but,, can't recall the specific name of this tube. 
But its far and away from a  true musical 6922. 
While every other Tele, Siemens, vavlo (both Red print and White) Philips RCA , GE etc etc ETCCCCC,,all sound nearly exact..
~~~~~Bottom line~~~ Do not waste your money buying the Tele 6922 pair froma  german seller for $1500, nor others selling any /all variety of 6922 for over say,,,$20 each,m, Yep you heard me right,, You should  never ever pay more than $20 for any 6922 type tube.
All those countless $50-$1500 and maybe even $2500 fora  pair of  NOS 6922 is pure 100$ snakeoil.
Now a  AX and a  AU, now here we do indeed hear minisclue differences, which make me a fan of Tele and only the Tele. a  Tele offers in my system superior resolution.. Not by much,, but as i've said countless times in all my threads,, a  nunace here, a  miniscule there, a  tweak here, a upgrade there = all adds up to a  superior  sound.
a  6922= 6dj8 = 7dj8, ecc88, =cc88 = 188 =288,,However my tech guy who lent me the russian non muiscal 6922, said this player is best using any 6922, except the 288... has a  dif heater value. 
So do not waste your money thinking a  over $50 pair of 6922's will improve your sound. 
A Tele 6922 is not superior to any 6922(preferable USA/EU) ever made.(just make sure its not chinese= I do not like chinese pretubes>>> nor russian military),,I have a quad of EH's comming in 1 week,, that is one 6922 I've not heard,,will report ASAP. 
rant over.
Snakeoil buster here,
,strikes again..
Toucheeee

Ok so general consensus is  there is more than justa  nuance dif, they all voice distinctly different, Ok, lets put this to the test
I want everyones general vote on one, Uno, not 2, just 1, as the <best/superior/king/champion of all 69222's, in terms of 
Soundtage/resolution of freqencies, separation of instruments, liquid mids, sparkle highs, voices the human voice near perfect.. (provided we are assuming,  all other components are able to match this feat of a  perfect 6922). 
As in the Olympics , there can only be 1 Gold Medal,, (which isa  scam of sorts, as in swimmers, the silver taking 2nd medal only due to a loss of .001 second, which on the next day , who knows the  silver may have beaten the Gold place)) anyway, only 1 6922 can win as Premier, 
As in AX,AU's only Tele's reign as Gold Medals, all others 2nd place. So which is it?? 
This I just got to hear,, everyone will have their own pick. 
Which leads me to my testing on at least 40 NOS EU 6922's, = all sounded near <<Identical>>
Nope , ain;'t buying folks, Sorry to go against the popular vote. 
Besides construction looks identical ,, no one here could say this is that lab, this is this,,w/o print on tube.
whereas a  Tele AU/AX are distinctly not like all the others. 
Tele AU/AX's has a  slight edge vs all others. I am talling nuance,, Some of you are saying there are HUGE, Grand Canyon size differences in sonics twix 6922's. 
How is this even remotely possible, when if there is no print on the tube, you can not tell me the  brand??
a 6922 = any other 6922. = a  188 = 288, etc..(exception are the chinese/russian tubes, russia and china never did nor ever will make a   good sonics pre tube) The New EH's are copies and good copies on any EU NOS.

I should have mention,, the pair of russian tubes lent to me are/are not actual sovtek,,, they have some odd number to them,, But lender (Richard Gray) did say they are Sovtek's.. But also said they are ****, which is some odd 6922, *original sovtek?) anyway,,here is a YT vid, Sovtek vs Tesla,, (should say, I HATE any Tesla, so huge bias there),,some comments prefered the Sovtek,, as i also prefered the Sovtek's. 
Not a  fair shootout as Tesla is the lowest grade of all EU tubes.
Tell ya what,, i will have my tube guy in washington state send me some 6922's, and will make some tests.
I'll try to reopen my mind about a  6922 variants.

,, But not sure if my Cayin CD17 is sensitive enough to pick up these nuances,, I'm thinking glad i only paid $25 for a  EH quad,, I don't like that design,, but when they arrive, I'll find out,,So yeah,, eventually i
'll save up for a  pair of Tele's..
In this shootout I  give the edge nuances to the Tele's.

I will say this, more bigger nuances to gain via new caps vs new tubes. 
Tubes only make a  slight nuance, whereas new caps, a  medium size nuance.

Subjectively, I prefer the cleanest, least colored sound, most 3D staging, most accurate tonality, I can get.     The Germany and Dutch Post shared that preference (back when/probably didn't care about sound stage) and contracted, "specially selected" tubes, for their services.      Make mine the early Sixties, grey shield, large halo, external date code, CCa.    ie:  https://www.tubemuseum.org/ProductDetails.asp?ProductCode=SH%5FCCa%5Fsingle                                                        Of course, as subjective and varied as listener tastes are; many absolutely love what seems to me the smothering warmth/glazed sweetness of the British tubes.     The early Sixties Amperex that I've tried, weren't as warm, but still......       I understand: Different strokes and all that.       When I had my shoppe, in Orlando, FL; I accommodated any and all tastes.
