A one-of-a-kind superb output transformer (OPT) is responsible for a lot of the
magic in the KSL-Neiro.
Kondo Audio Note Japan has spent 10 years to solve how to obtain the
sound equal to 'silver wired' OPT by means of copper wired OPT. Through trial
and error, Kondo has at last discovered a new wire winding method in KSL
technology. 10 years in the making.
KSL technology was first developed as a line cable, which received raves as
being sonically superb after it was marketed. The KSL OPT was developed in the
same configuration as this line cable. The KSL-Neiro features natural smoothness
and fine separation where each note and tone is truly felt.
Conventional single-ended amplifiers have 'much distortion'
because of non-linearity of a power valve and 'much
distortion in low frequency range' due to lack of inductance
as a result from allowing audio signals (AC) to flow
together with DC to the OPT.
KSL-Neiro has solved both problems by parallel coupling of
2A3, resulting in low inner resistance of 800 ohms, as well
as doubling the output power thanks to a skillfully designed
circuit structure.
