PM7001 KI - Signature Integrated Amplifier
The KI Signature series is for years a pseudonym for finest electronics with best sound quality. Every
aspect of the design and construction of the PM7001 Modified 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.
