KECES S4 Preamplifier & Power Supply Black Demo
Contact for AUDIOFEST PROMO!
Single-ended, zero feedback circuit topology and demanding pure Class A operation and removing the need for a phase splitter.
Fully symmetrical construction and offer a wide range of symmetrical (XLR) and asymmetrical (RCA) inputs and corresponding outputs.
The pre-amplifier circuit boards are of symmetrical double-mono construction.
The elaborate volume regulator is created by an R-2R network that has the same impedance at 128 possible, logarithmically tuned levels and guarantees an extremely good synchronism down to the lowest volumes.
The new design uses low noise toroidal transformer in external supply.
Build in DS audio EQ and MC/MM phono.
Build in high-quality headphone amplifier.
All-metal infra-red remote control handset.
The components and materials employed are uniformly of top quality.
