Regarding the CSP:
 
I'm curious to try the Gold Lion 6922 but it probably won't live up to the super$$$ tubes I've tried: Dario Miniwatt E188CC, Mullard 7308, etc.
 
Currently I've settled on the tried-and-true Mullard E88CC w/old shield logo. No need to use three. Keep the 6N1P's in the driver slots to save cash (the sound is pretty much identical anyway).
 
For the rectifier I'm using a Brimar 5R4GY which is great, though the RCA 5U4G (black base) is a good & cheap alternative. Also try the Sylvania or RCA 5Y3GT just to see if you like the 5Y3 sound (I didn't care for the Tung-Sol version but it is a popular choice).

I found a 12bh7 to sound best in my rig using the same pre-amp and amp.

What manufacturer?  RCA, Tung-Sol?
 
 
 

Or a 5751

I'll look at these as well, GE gray plate? 
 
 
Appreciate the input, thanks!

I have a bunch of 5751s but the one I use the most is the Raytheon with the windmill getter.

Seconded the Raytheon blackplate w/windmill getter. Always a good choice.
 
The only 5751 I found to exceed it was a yellow label Sylvania JHS 5751 triple-mica blackplate.

This is a good description of 12BH7 variations:

Gold pins?

I'm currently using Sylvania Gold Brand 5751 triple mica black plates as drivers on my ST-70 - they're excellent.  I've also been a fan of the Tung-Sol long plate 2-mica 5751's.

I don't recall. Might have gone either way.

Yeah I remember the Tung-Sol long plate 5751. I call that one the "Pink Floyd" tube... lush and syrupy but great in the right amp.

I think this just came out today.  My appologies if it is not new news.
 
Its a redesign of the Taboo specifically for planars.  Dual lucid mode...

Why does Steve say in his post that you can't listen to the Taboo with a single ended headphone when it is not in lucid mode?

Do you think you need the gain of the 12ax7 ?  With the CSP2+/Taboo combo a 12au7 should be a better fit.  I found a 12bh7 to sound best in my rig using the same pre-amp and amp.
 

When I owned the Taboo I used the Mullard AT7 old stock from Upscale audio. I tired 12bh7,5751 and the 12AU7 Mullard and some 12AX7 olds tock and it always was the Mullard 12AT7 I found to be best in gain and alsao the best sounding tube in my rig. I used Genelex 6922  for 2 years and now am using the Bugle Boys but make no mistake the Genelex is the finest current production 6922 IMO. I love the Buglr Boys  and have other ones also for rolling but these are in now the csp2 and I sold my Taboo. The 12 AT7 was my favorite tube for the Taboo

LLooks like there is a new Taboo coming for 500.00 more designed during the christmas break.  I guess you can ask if he is going to offer an upgrade path for your amp.

 

[dminches]

I already did but he hasn't responded yet.

Don't mean to be rude but my experience is opposite of yours.

I tested many matched pairs of NOS tubes for the driver position before settling on the Siemens E188CC for my CSP2+.
There was a major sonic impact for me and some tubes like Siemens CCA didn't work so well.

As for the rectifier, the 5U4G didn't work so well for me. The 5Y3 and Brimar 5r4GY which I'm currently using sounded the best in my setup.

The Russian 6N1Ps require more juice and so I hypothesize that they would sound better with a 5U4G.

YMMV. I suppose?

But one thing I agree with you is that one can save big time by using only one uber expensive tube in front.
In my system, I have one single Pinched Waist Amperex 6922.
