1975 New Reflektor 6n23p SWGP or Siemens/Amperex/Telefunken Cca?


Contemplating shooting for the moon with the 6DJ8/6922 tube type.  The moon appears to be either the 1975 New Reflektor 6n23p SWGP or Siemens/Amperex/Telefunken Cca.  For reference, the link below asserts the former is the Holy Grail.

Curious what the here assembled opine.

Would be installed into a 2006 Dodd Battery Powered Preamp that is currently populated with early 1960s Siemens large halo getter e188cc (7308), which are great.  Objective of the moonshot would be more of the same that the current tubes are delivering...if such is possible.  Or, as any card carrying audiophile would espouse, something even better.

Thanks in advance for opinions, particularly from any audionaughts who have taken this particular journey.

@xenolith -   Sounds as though our sonic palates are similar.      Given you got those from Kevin (very reliable NOS source): in most circuits, they should last around 10K hrs.      Brent's another of my favorite tube mongers.         You're probably already familiar with his views, on the 6922 family, but- just in case:          http://www.audiotubes.com/6dj8.htm
Love this place. 

Once had a mentor tell me "All good scientist must have a latent masochistic streak"...what he meant was that, necessarily, scientists must enjoy the suffering that necessarily predicates the solving of hard problems.

Could be wrong, but, I think that audiophiles, by that definition, are good  scientists.  





  
Yo petg, just bought 4  Voskhod 6n23p "1970s for export" Nationals

4 for the price of 1 Cca

The nervosa cure didn't last long

 
I'll make sure to do so rodman.  They're coming from Poland with estimated delivery between March 2 and March 19, so will be a while, but I'll for sure return the kindness of you and the other Audiogoners who contributed their hard won experiential insights to my inquiry in this thread.
