In Reply to: RE: Great news if these proof to be anywhere close to Black Gate WKZs posted by Nickel Core on November 11, 2014 at 04:19:00
I think a little skepticism is in order, a priori. Just sayin'.

I wonder if the blackgates were ever really any good to begin with?
If you ever really tried them.

I know there are them that likes Blackgates and them that do not like them. My skepticism would be around the notion that because of the fancy wrap on these new AN products it necessarily means that the internal construction is exotic, in a good way. It's just possible that PQ sees a market niche that has been vacated since the HV Blackgates were discontinued and is seeking to capitalize on it. I personally am quite happy these days with HV Nichicons and Panasonic TS-ED, etc, when I do have to use a 'lytic. I definitely would not pay a very high price for those new Rubyons, unless there was something demonstrably exceptional about them. That said, I do very much like Rubycons in their very low voltage ratings, in solid state gear, for example.
I've visited Audio Note UK a few times the past two years and witnessed the development and evolution of these capacitors. These are not simply a rebranded Rubycon with a gold wrapper and AN logo on it. Since the discontinuation of the Black Gate products, PQ and team have been working closely with Rubycon for years on this project and made trips to Japan to work with their engineers and materials specialists to create numerous prototypes to arrive at the products you see offered now on their website. I know of no other audio company making such effort and investment to continue the advance of this category of component for audio use.
Do you know anything about pricing?
Pricing is posted on their webpage. See link below.
From 12:30 on...
Poor tolerances, do not meet voltage spec, ESR higher than equivalent Panasonic by about 30%.
I tried Blackgates for about 6 months, because a number of my customers requested them. Had to stop using them due to about a 25% failure rate being run anything approaching 3/4 voltage.

I have used them all my life, and never have seen one failed.
I don't care much about ESR (although the BGs I used had almost immeasurably low ESR and where always close to spec). I care about how they sound in a circuit.
I only have experience with the more expensive BGs types though.

Pretty much all the lines, except the bipolar ones (can't remember the nomenclature). Poorest cap I have ever seen used, excluding the Chinese junk used in a lot of stuff today.
