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.

Try to get some 6n23p Voskhods 74-79 period and you will never look back, problem is to find a good and trusty vendor for these. They have a better pricing compared to other 88 family nos, have less tedency to microphonics, and generate less heat around the tube. I have tried nearly all in that family and i am happy to have a good stock of these and selling nearly all my nos stock of ecc88/e88cc/e188cc. Just kept some Holland ecc88, e88cc, e188cc, Siemens e188cc A frames (which i find better voiced than CCa's). D-getter Bugle Boys ecc88 and Amperex Holland e88cc straight D-getter 1958-1959 period are special but can become noisy. All depends on your gear and how hard it drives the tubes.
Another nice and linear sounding tube is Mullard e88cc-01, equivalent to CCa but unfortunately same pricing and more rare.

@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.
