The
Audio Note Japan preamps are known
worldwide for their musical bloom.
These triode
preamps use no overall
negative feedback in line section, error correction or
solid
state power supply regulation
(except for the filaments). They are
designed
to be as simple as possible.
Minimum
parts,
passive (no feedback)
circuitry
and
components
of the highest quality are the primary
design
criteria.
The
simple use of tubes in the Kondo - M-1000 MK II, KSL-M77
and KSL-M7 preamps are one of the key
reasons that these products reproduce music with such a strong sense
of wholeness and continuity. Tube rectification opens up the soundstage
and allows the music to "bloom". The melody flows naturally,
like a river. In contrast, solid state rectifiers emit electromagnetic
pulses that resonate throughout the audio circuit and add an electronic
haze that can be perceived as a highly unnatural noise or grain.
The unnaturalness of the solid state rectifier's turn on/turn off
cycle creates a choppy, edgy feeling that over-emphasizes the leading
edge of transients at the expense of a harmonic completeness and
does not allow the individual notes to rise and decay naturally.
There
are three preamplifiers in the Kondo Audio Note Japan range, first
came the KSL-M7.
