PM7001 KI -
Signature Integrated Amplifier
The KI Signature
series is for many years synonym of finest electronics with best sound quality.
Every aspect of the design and construction of the PM7001 KI stereo amplifier
has received Ken Ishiwata's personal attention to attain uncompromised quality.
The copper-plated chassis and rear panel reduce signal-degrading
electromagnetic interference, while its rigid dual layer chassis and solid
aluminum front panel virtually eliminate mechanical vibration. Delivering 2 x
70 watts into 8 ohms (120 watts, 4 ohm), this 2-stage constructed Current
Feedback amplifier features symmetrical circuits for perfect image balancing,
and uses audiophile Customized Components and the new HDAMs to preserve the
music's dynamic structure, tonal quality and stereo image. Power handling
characteristics have been reshaped and the large toroidal transformer is
designed for this renewed circuitry. Its low impedance, wide-bandwidth power
supply ensures a massive reserve of energy, to drive even difficult speakers
with ease. Enjoy the exclusivity of the Ken Ishiwata Signature integrated
amplifier.

A touch of Ken
Ishiwata
The PM7001 KI is a
clear example of benchmark engineering and craftsmanship of Ken Ishiwata and
features a number of Marantz sound enhancements. The PM7001 KI integrated
amplifier is built on a rigid dual layer enforced chassis. All of the analogue
signal and control circuits are separated and shielded to prevent cross-talk
and other unwanted interference. A high grade power supply centered around a
special selected toroidal transformer secures maximum separation, clarity and
dynamics. This design configuration is capable of a clear and powerful
reproduction of the most demanding musical performances. The strength of each
KI Signature design can be found in the attention to detail and the synergy of
the different elements
