TAKUMI K-15 EX
El preamplificador Takumi K-15 EX es nuestro preamplificador insignia y se basa en las tecnologías que se encuentran en el galardonado K-10. ¡Todos juntos más sofisticados, refinados y atractivos, el Takumi K-15 EX es seguramente una forma definitiva de preamplificaciones!
Toda la placa de circuito diferencial de equilibrio verdadero dentro del EX es completamente nueva. Técnicamente hablando, es un preamplificador completamente nuevo. La siguiente imagen de arriba es un espectrógrafo. Hay 7 frecuencias singulares alimentadas en el amplificador y están representadas por 7 puntas verticales agudas que cada una asciende aproximadamente a “-95” en la escala vertical en el lado izquierdo.
Tanto K-15 como K15EX muestran las 7 frecuencias singulares. Ahora mirando más abajo hacia abajo, puedes ver un montón de líneas verticales más cortas, en su mayoría en rojo. Cada una de esas líneas representa una nueva frecuencia que el amplificador ha generado (distorsión) y la altura de cada línea indica la intensidad de cada distorsión.
Verá que también hay un poco en verde (que se vuelve amarillo si coincide con el rojo). El gráfico verde es para K15EX y el gráfico rojo es para el K-15 original. Esto NO es una ilustración. Es una simulación de alta potencia.
Los resultados muestran que K15EX hace sustancialmente mejor que el K15. En promedio, no solo la intensidad de cada distorsión se reduce en unas 30 veces, sino que también K15EX tiene un menor número de ellas para empezar.

DESCRIPTION:
The entire true balance differential circuit board inside the EX is brand new. Technically speaking, it is a completely new preamplifier. The following picture above is a spectrograph. There are 7 singular frequencies fed into the amplifier and they are represented by 7 sharp vertical spikes that each go up to about “-95” on the vertical scale on the left hand side.
Both K-15 and the K15EX show the 7 singular frequencies. Now looking lower down towards the bottom, you can see a whole bunch of shorter vertical lines, mostly in red. Each of those lines represents a new frequency the amplifier has generated (Distortion) and the height of each line indicates the strength of each distortion.
You will see that there is also a little bit in green (becoming yellow if it coincides with red). The green graph is for K15EX and the red graph is for the original K-15. This is NOT an illustration. It is a high powered simulation.
The results show K15EX does substantially better than the K15. On average, not only are the intensity of each distortion reduced by about 30 times but also K15EX has fewer of them to begin with.

Robert Koda
While it is true that Robert worked under the guise of the legendary Hiroyasu Kondo of Audio Note (Kondo) Japan in Tokyo, Robert is actually self-trained and an independently motivated creator of audio electronics.
Interest and research into the interaction between technique and musical satisfaction began at the very early age of 12. While within the era of the transistor, ironically it was vacuum tube that first captured Robert's attention.It was a musical home from which Robert was raised, music and high-end audio always important. His mother and father's purchasing of a new home would invariably involve the analysis of acoustic suitability of the main living room before further consideration.More than 16 years experience in the field of high end audio distribution, retail, installation, servicing and all the contact available through this career with vast arrays of equipment of those times fueled a hounding sense that things could be done by him and be done right played a major role in his life and lead to the development of a system that by 2004 captured the results of this life long work.Its architecture was both simple yet elegant and redefined the inherent structure of digital / analogue playback technique. To visiting audiophiles it yielded a propinquity to completeness not experienced before on replayed music. The system was deemed startling in its unique ability to transcend the sound of both transistor and vacuum tube - The amplifying devise.Drawn from those works, refined, perfected and matured Robert Koda now offers a select few the opportunity to own and enjoy these hand crafted works of musical beauty.
"The desire now to offer fellow music listeners the same complete listening
experience finally persuaded me to produce commercially available options -
the Robert Koda brand."
