Just in.. AudioNotes flagship capacitor Kaisei. Most likely developed to fill in the BlackGate WKZ gap and also manufactured by Rubycon as noted on the cap itself..
Really curious about their performance. I will try them in the EL84 SingleEnded as second and last capacitor in the power supply: 100uF + 100uF and 5uF per channel for the 6AK5 driver.
