Patek Philippe of high-end audio volume controls? Robert Koda Takumi K-15 custom made (audio nude) resistors fully mechanically driven volume control with four channels of operation in a L-Pad mode requiring a configuration of 8 X 34 position switches. Exotic, extreme monster!
I love my Robert Koda Takumi K-10 preamplifier, but this bigger brother for sure won’t let my mind at ease…
