When it comes to the top of the mountain for signal path electrolytic capacitors, nobody seems to be able to beat Black Gate™ capacitors. The price tag on these boys is just outrageous. I was able to buy 6 of them for just under $80 and those were used!! They definitely did impress me though, I can’t argue with the performance they seem to have. The ESR was so low, one meter couldn’t read it.
