The Robert Koda K-15 preamplifier red efi nes St at e of t he Art and
presents music as a fresh encounter of a most indulgent and satisfying kind.
Specifically designed to partner with a wide range of source components and
power amplifiers, its purpose is to extract the maximum performance from each
component so that the system as a whole delivers uncharted musical pleasure.
While this brochure highlights some of the methods we used to create the K-15,
there can be no substitute for a personal encounter with this magnificent instru-
ment.
