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

"care to elaborate on how you tell a Tele from a Amperex?? please?"                                                                EASY; the Amperex (early Sixties, Navy 6922) was a little warmer than the long-plate Tele, in the mids.    Compared to Teles and Siemens; the Brit tubes (ie: Mullard, Brimar) reminded me of glazed donuts.     Just not my taste, in food or sound.        Every NOS tube I tried had a more extended and more solid bottom-end, better sound stage, tone, etc, than the six Sovteks that were stock in the CDP.

Exactly 
My friend lent mea  pair of <<Sovteks>> = Military crap. 
Yes every USA/EU 6922 is far far superior to any Sovtek which as you say comes with some units.
I have a  quad of EH's arriving,,hoping they can meet EU standards.
My unit is sensitive,, or how would I know the Sovs sounded anti-musical,, those were built for battle eqip , not hifi.
Again, I  stand by my thesis, that every EU/USA 6922, the sonics are so close,, its a  mini-minscule dif in sonics.. Now its true I have made some changes in my system,, perhaps now the difs may be herad more clearly,,, But at this point, I have no cash for  rolling tubes,, The point of this topic is don't spend big cash on 6922;'s, as these are not made with the same sensitivity as the AX/AU.. Now in these 2 pre tubes, sure each brand will have more nuances in sonics.. Not much, but enough to make me a  solid fan of Tele and no others. 
But as far as 6922, my top budget is 25 a tube, as the sonic difs ,, I am more than confident are so mini-scule,, makes no sense spending more than $25/each.
My posts are locked in google now, So if in decades to come, someone is researching 6922 shootout,,he'll read my posts and save his cash for other tweaks. 
This is the purpose of my topic,, and not to convince you hard liners in this snakeoil of 6922 high priced tubes. 
I respectfully disagree.   My pre uses a single 6922 and it absolutely makes a difference in that preamp.  A Gold Lion sounds different than a JJ 6922, different than a Reflector 6h23n eb.....

They all sound good but they are definitely different 
I didn’t mention the two ARC preamps (SP-9 and SP-14), I owned before the BAT CDP.       Both of which also displayed remarkable differences in presentation, with various 6DJ8/6922/E88CC iterations.       Didn’t matter where the tubes where manufactured.       Of course; who am I, to tell another what valuation to place on their system’s presentation, or- it’s possible enhancement?     The Audio Pope?
