It would be great if someone did a review on tubes based on:
 
1. Price 
2. Sound Signature, Characteristics 
3. Performance 
(And not just the best of the best E88CC tubes)
 
What I have gleaned so far (very noobie at this point):  
It seems the 60's Telefunken seems to be the highest priced, best or most desired sound characteristics and performance
Followed by Siemens and Amperex 60's
(Mullards and Genalex Gold Lion with their overly lushness seems to be a preference thing that few people really like) 
Than Tesla being a budget tube but still much better than Lyr stock tubes
Lastly Voskhod right below it but still better than stock Lyr tubes.
 
I could be totally wrong but just guessing.

sling5s,
 
Price is a big deal for me, for I am frugal. If price is an important criteria for you, you may want to review the following:
http://www.ebay.com/itm/6N23P-VOSKHOD-1974-EXACT-DATES-SINGLE-WIRE-POST-Pr-US-SELLER-6922-/231397668106?&_trksid=p2056016.l4276
 
I have have '74, '75, and '79 Russian tubes including Voskhods and Reflektors from rb2013. He is selling them now at very reasonable prices--something about needing Christmas money. I have been very happy with the three pairs I got from him and his customer service and delivery times are great (US). Not to say I won't explore more expensive and non-Russian tubes, later. If the tubes above sell before you snag them, he has others on ebay and you can always message him via Head-fi (rb2013) and make an inquiry.
 
Heck, I use a pair of '79 Voskhod tubes that I paid $39 for most of my day to day listening and they are pretty damn good.
 
Hopefully, I have helped. If not, apologies.

Well I think that is not a good summary.  This tube stuff does take some time research and just reading a few of the lastest posts won't give you a good overview.
 
But here are few places to start - you'll also want to identify your price range.
 
On the 6n23p Voskhods and Reflektors here are some summary reviews I posted:

  got to agree i got the Holy Grail rare Russian tubes , 275$  but they made me love the Lyr II even more, for me the stock tubes are a crime!! they give you warm mids but you lose a lot of dynamics!!!!
 
 some people like it like this, for me i went for the Lyr II so i dont lose dynamics and still sustain the warm transparent mids.
 

The tubes Shini44 speaks about I call the Holy Grails ('75 Reflektor silver shield single wire getter posts) - as they are just incredible. Really takes the Lyr to another level.
 
The discovery of these amazing Russian tubes is a fairly recent development in 6922 history.
 
From Tubeworld's excellent website some of the more typical rankings for the 6922 are here.

I've owned almost everyone of these tubes, including the Amperex 6992 '50s D getter pinched waists and Holland 6DJ8 pinched waists.
 
I can say that the very best 6n23p is better.

I knew I would be off and speaking of out of ignorance but just thought it would be great to have some comprehensive review of all different tubes like many have with IEM's, amps and dads. But I guess there's just too many factors involving tubes.

Anything is helpful.  Thank you.  I'm going to try to get some used Telefunken and some cheaper Teslas and Voskhods as well.

You're not off at all.  rb2013 and others have posted many reviews/comparisons in this thread (and the old one, which I am slowly making my way through).  I have a pair of 1974 Reflektor gray shield single wire getter posts I purchased from rb2013.  Not the Holy Grails he references above, but they are some damn fine tubes for around a hundred bucks.  Far better than the stock tubes or Bugle Boys that came with my Lyr when I bought it from another head-fi'er.

The first line of the code should start with DJ (for PCC88).
 
The second line has the factory code (if B, that's Mullard, Blackburn), digit for year, letter for month, and (possibly) digit for week of month.
 
Here is an example with Heerlen factory code:
 

1. http://www.tubemongerlib.com/gallery2/v/6DJ8/Amperex+Philips+PCC88+7DJ8+-+1964+Halo+Getter+Philips+Label+-+Heerlen+Holland.jpg.html

 
The code is:
 
DJ5
delta4L2
 
 
That might help.

I appreciate the best code breakers help!!! I understand code for PCC88 SHOULD BE "DJ". I have tried to present photos of tubes, one tube smears, the  other: 7G-B36, just what it says!!
Doesn't really matter to me, sound really good.

No worries  you were pretty close.  The great thing about tubes is they can allow a listener to tailor the sound to their system and tastes.  Very flexible, with the ability to scale up the sound later after you buy the amp.  I think we've all found the Lyr/Lyr2 amps are sensitive to tube changes.
 
So folks will have different favorites and what this epic thread is all about.  When I originally 'discovered' the better vintage '70s Voskhods - I wanted to find out if other folks have similar impressions.  I've been rolling 6922s for over 20 yrs (back then price were way cheaper!  Siemens '60s gray shield CCas were $200/pr), I knew these rare 6n23p's I'd come upon were very special.  So I began posting my results from buying and trying the different yrs and constructions.
 
Initially the response (on the old thread) was severe skepticism, as folks had tried the new production and 80s - 90s production which are good but not great.  But as folks tried the better '70s Voskhod 6n23ps the feedback was almost universally positive.
 
So this thread has broken new ground in 6922 history.  Of course there are many other great 6922 tubes from Siemens, Amperex, Lorenz,Telefunken, etc...
 
Here is a comparison I did of a few different Amperex's and the Russian 6n23p's:

Just got a matched pair of used Telefunken ECC88.  Hopefully it will be an improvement over the stock Lyr.

The code is a mystery but in the auction photo they do look like tubes made by somebody with access to Philips machinery.

Why were these so cheap?  Are there something wrong with these Telefunken tubes? 

 

[MWSVette]

I should probably ask this before I buy tubes.  I just splurged on a set of Amperex white PQ 6922 tubes.  Dated 1962.  Has anyone used these in their Lyr?  If so how did you like them?  Are they as good as I hope?  Cause the wife is gonna kill me when she finds out.
 
Thanks...
