Black Gate caps address several limitations of elcos using two main technologies:
graphite and titanium/palladium dispersed on the dielectric.
Those particles reduce the idrogen produced during cap work.
Those things are better described in Jelmax's patent US5057972.
From what I know that patent should be expired.
The only caps that has similar aproach are Mundorg MLGO, their electrodes are treated with titanium oxide so to reduce hydrogen, like Black Gates.
In fact those Mundorf, produced by F&T, are far better (and costly...) than any other elco in production.

This is the company Elliot from Sonicraft referred me to for top end speaker components. They may have, or will build, or can refer something for us. I will contact them also.

Is this what you are describing ?
MUNDORF M-Lytic AG Series MLGO+ (Glue-On) & MLSI+ (Snap-In) 2-Pole Electrolytic Capacitors

You already have them in C101 and C201...
P.S. Your collection of data and knowledge of specs blows me away
It's simply curiosity...
Yes you did... C101/C201 are the big smoothing caps...
I was talking about BGs in general and MLGOs are the only current production caps that have similar performance.
Sadly they're available only as snap-in type and high values, so not suitable for C9.
Told you it was easy . C102/202 is what drew my attention due to the size of the cap. I guess I was hoping too hard for there to be a viable alternative. I think I will just go back to building speakers - top, bottom, left and right are a lot easier for my aged mind to comprehend. 
You guys just have way too many numbers.

I think you can't resist to build amp/preamp and DACs...
Since Mundorf has been brought up, anyone up to spending $84 each on a Mundorf M-Tubecap polyethylene film cap at 200 uF?
More seriously, Mundorf would be a natural to fill in the lower capacitance value range that Black Gate covered using their MGLO technology. Mundorf already has a name and a market in high end audio. I think they should start with a 220 uF cap.
Anybody know anything about JJ Electrolytics? They were well thought of on a different DIY Audio thread. They seem available (Amazon, PartsConeXion, maybe ebay) but large because of their higher voltages. Seem aimed at tube amps.

I've used PKs in the MINI24/96 DAC and tried them also in the MyRef in C6/C11.
They sound more refined than STD, similar to FK but a bit less full.
I've ordered some too from PCX to try, I expect them to perform very well in C9.
A note... both BG NX and PK have a very low voltage rating (6.4V and 4V) and, until the amp works correctly this is not a problem.
But if something goes wrong in C9 goes full rail voltage (circa 35V) so that cap is likely to be destroyed and must be replaced.
I suggest to take some more as spares or to mount them only when the amp works perfectly, until then use some generic ones like the FG in BOM.

Rubycon are still around, one of their factories is 15 mins from my place and their headquarters is less than an hour away. I expect the Japanese audio crew have lobbied them to produce the black gate series again? (Anyone from Japan lurking here please PM me I have no local audio fanatic friends!)
I heard there was some specific production problem, any one have more information?
If it was purely a financial problem they could re-introduce the black gate series as a 'boutique' cap and we would still be better off than paying the current outrageous prices for remaining stocks.

I was too slow editing my post.....
Here is the edit....
I'm sure most people know that Rubycon are still manufacturing, one of their locations is 15 mins from my place and their headquarters is less than an hour away. I expect the Japanese audio crew have lobbied them to produce the black gate series again? (Anyone from Japan lurking here please PM me I have no local audio fanatic friends!)

If it was purely a cost-effectiveness problem they could re-introduce the black gate series as a 'boutique' cap and we would still be better off than paying increasingly outrageous prices for remaining stocks.

Sadly, I think Rubycon realised that there aren't enough people listening carefully to music anymore (the age of surround sound and compressed storage), they turned their attention to making specialist capacitors to fit in flat screen TV.
Bored you all now I expect.... !

Just sent the email off to Intertechnic (True Copper mfg.) in hopes a smaller company might be interested in investigating the possibility of a new offering based in BG technology. I included Dario's patent references. I also asked if they know of any other company that would have the interest and capabilities. Hope they respond.
Never tried F serie but I expect them to be better than STD and very similar to FK.
