I am delighted that you so enjoy MC
I am not shy of transformers even
though they may not always measure well. For sure transformers can bring upon
merits in the right (and very carefully controlled) circumstances.
Perhaps we should not delve too deeply
into the technical core of design but I will say - While most engineers love current
sources as active loads and understand no harm, not all is that simple...
Emperor, I am delighted that you are
enjoying our MC-One and many of your recordings are sounding like
I would like to present the subject of
“Dynamic Noise Floor” to our readers. There is much confusion in
both audiophile and engineering circles... So I shall say, there is
noise floor, the static one you can measure with ease. It is static,
and unless very high in level, benign and unimpeding to the enjoyment
of music replay.
Static noise floor is one of those
measurements manufacturers present on their spec sheets and ask you
to believe in its relevance with blind confidence. Indeed even the
cheapest digital systems can excel in such specifications, leaving
the most advanced analog systems far behind.
Then there is “Dynamic Noise Floor”
as coined by Robert Koda – DNF. Not so much a noise but rather a
gritty and shifting ghostly shadow, a clogging mush that is changing
in a continuous and dynamic way yet somehow related to the music in a
It stems from the music its self when
passed thru a piece of electronics or system. It is the ultimate
corrupter and its nature is a direct result of a multi fold of
complex interactions occurring within the make up of the circuitry.
It may manifest its self in transients, or perhaps decay.
Specifically in every event and every moment of music. It is our
opinion that DNF is the single greatest contributor to the inferior
sound of a components that otherwise “measure” so well. DNF is
perhaps the Achilles heal of modern electronics...
Much, if not all of the DNFs make up is
spread across the time domain – An occurrence in the past effects
the result of the near future. As you can imagine, the effect has
catastrophic consequences on music replay!
Robert Koda realized the existence of a
musically modulated and ever changing Dynamic Noise Floor decades
ago. Within the past eight years or so in particular we have
endeavoured to understand the underlying mechanisms of DNF. Indeed
this has become one of the keys in our Research and Development program
and has almost certainly resulted in the (sonic) success of our K-10,
K-15 and now MC-One.
I hope this short note has given you
greater insight into the “Whys and Hows” of Takumi MC-One.
