I just picked up a matched NOS set of Telefunkens from Brent Jessee.  Not the expensive 6922, but the slightly more affordable 6DJ8 / ECC88 Telefunken West Germany with diamond mark.  GM: 10,500/10,000 10,500/10,000.  They are still breaking-in I have about 20-hours on them. 
 
So far they have been very quite.  These tubes are fast and very detailed with a lot of air around the instruments. Piano is really sweet sounding standout on these Telefunkens.  Their tonality is neutral in the bass and midrange to slightly bright in the highs, but not overly bright.  They seem to pair well with my Grado PS-500 more so than my AKG K702s.
 
I’m hoping the highs will mellow just a bit with a 100-hours on them, but they are very nice right out of the box. If you are looking for maximum detail, neutrality, and air, then these Telefunkens are worth considering.  If you want the classic tube warmth, then I would suggest you look elsewhere.

Had to try out the Bugle Boys so I bought a used pair of eBay for $20.00 plus shipping.  I read the earlier post on the fakes and these seem to be the real thing. Here's what was in the listing:
   
   One Matched Pair Philips Amperex Bugle Boy 6DJ8 Tubes, Vintage Year 1967
   Since I purchased them 1 month ago, I used them only about 2 hours using to test them in my audio rig.
   My preference to other tubes, I decided to sell this pair. Written below is the original seller's statement.
      One  matched pair of Amperex Bugle Boy 6DJ8 tubes, by Philips of Holland.
      Good silkscreen.
      The engraved codes are  delta7A4 and delta7G4.
      Medium ring  getter.
      Good test ratings.
      Test ratings: 95/95% and 95/95% on my Jackson 648S tester. Min. at 70%, new tubes at 95%"
 
Did my usual DeoxIT, rolled them in and have been running for about 1/2 hour.  Sound seems pretty clean but maybe not as engaging as my Orange Globes. Still way too early to tell but for $20, what the heck.

Absolutely!  Worth a shot!  I like the OGs better also, but my BBs are still really nice.

Question - how do I get socket savers out of the Lyr? I guess I will have to take the Lyr apart? 
 
They do not come out when I pull the tubes.

If you wiggle the tubes the right way the socket savers will usually come loose (at least my Tubemonger savers do).

 
Mine are also Tubemongers. I tried that but it just bent the tube pins a bit. I think the tubes I'm running are old and the pins may be weak. 
 
I guess I can try it with another set of tubes to see if that does the trick.

Needle-nose Pliers will work (make sure the power is off!).

Do you grab around the socket saver? Or, in the pin holes? Seems like there may not be enough room for the tool.

Grab the socket saver...don't stick anything in the pin holes (except pins).  Another trick is to find a tube that fits tight in the socket savers and try to use the tube to work the socket saver out.

I have one saver that stays in the Lyr when the other one comes out easily.  I have a set of needle nose pliers that are really long and thin...that's what I usually use.
 
Hope it helps...
