Review:
KECES S4 Stereo by Carsten Bussler @ hifistatement.net
“After just a few pieces of music, I realized that I was dealing with a very balanced, harmonious and neutral sounding preamplifier. The KECES S4 had no inherent sound signature whatsoever. Somehow this preamplifier was tonally invisible, in the best sense without a specific signature, extremely permeable to everything on the record and thus very close to the ideal of the amplifying piece of wire. I identified no interference artefacts, perceived an extremely low noise floor level and a black background against which the musical performance contrasted perfectly.”
