Premium Electrolytic Capacitors for Audio

Longtime audiophiles will recall the sensation of "Black Gate" electrolytic capacitors. Made in Japan by Rubycon until August 2006, these capacitors have been revered for their sonic qualities. Prices on NOS Black Gate caps range from $40 to $500. We have always sought out the best components in the world for use in MicParts and Roswell microphones. This led us to partner with Rubycon to create what we feel is the best electrolytic capacitor for audio on the market today. These Roswell capacitors employ special foil, special etching, and custom formulations of electrolyte -- all based on the original Black Gate designs.  The available inventory appears below. We have no plans to make every possible value/voltage combination; rather, we focus on the values we need for our microphones (including the tube mic power supply). As compared to other capacitor suppliers, our limited selection favors small size (because microphones tend not to be arbitrarily large) and low voltage (because most
