The PM7001 is an integrated amplifier developed on the design concepts of Marantz’s PM-11S1 high-end model amplifier.

• CD Direct Buffer Amplifier

The PM7001 incorporates a specialized input buffer amplifier nearby the CD input jack.This buffer amplifier faithfully transmits the CD input jack signal by preventing interference from between the left and right channels, and from the effects of other circuits. A discrete configuration high-speed buffer amplifier which is built on the HDAM®SA technology is incorporated into the buffer amplifier circuit.

• CD Direct Selector

The output of CD direct buffer amplifier has a specialized relay switch, which directly transmits the input signal by the shortest path to the pre-amplifier.

• Improved Momentary-Current Supply Capability

It is known that sound quality differs between amplifiers that use the same spec, and Marantz believes that this is caused by differences in speaker drive capability. The PM7001 main- amplifier has the capability to momentarily pass 25 amperes or more of current, providing high-powered drive to the speakers.

• Short Power Line Layout

In order to improve the momentary-current supply capability, a new layout which places priority on making the large current line connections as short as possible was adopted.

In this layout the power supply circuit, main-amplifier output stage, and heatsink are unified, and the large current line is arranged to be as short as possible while still achieving symmetry on the left and right sides.

• Current Feedback Amplifier

Both pre-amplifier and main-amplifier incorporate a high-speed current feedback amplifier circuit, which faithfully amplify signals from the CD player. Moreover, the high-speed current feedback amplifier reproduces a natural sound field space.

Compared to the PM7001, the PM7001 KI version contains the following upgrades.

• Current Feedback PHONO Equalizer

A high-speed current feedback circuit similar to the pre-amplifier and main-amplifier circuits was adopted in the PHONO equalizer for the MM cartridge.

• Newly Developed Toroidal Transformer

A newly developed Toroidal power transformer, which produces less vibration and magnetic leakage flux than previously, has been incorporated. The materials and manufacturing process of the ring-shaped core are strictly controlled to reduce vibration, while the short-ring attached to the perimeter of the transformer reduce magnetic leakage flux.

• High Performance Volume

The volume controller, which is often considered to be the core function of an amplifier, has been upgraded to an even more reliable type of controller.

• Large Capacitance Block Capacitor

A large capacity 18000∝F block capacitor is incorporated into the main-amplifier power supply circuit.

• Film capacitors and electrolical capacitors etc.

The capacitors used in high end models like the PM-11S1 are incorporated into the PM7001 amplifier.

• Copper-coated Chassis

PM7001KI specifications

The Marantz PM7001KI is a high-performance integrated amplifier that exemplifies the brand's dedication to audio excellence. Designed as part of the Special Edition series, it serves as a tribute to the legendary audio engineer Ken Ishiwata, who significantly contributed to Marantz's legacy. This amplifier combines both elegance and power, making it an attractive choice for audiophiles seeking superior sound quality.

One of the standout features of the PM7001KI is its robust power output. With a continuous power rating of 70 watts per channel into 8 ohms, and even more at lower impedances, this amplifier can drive a variety of speakers with ease. The current feedback amplifier design, a hallmark of Marantz engineering, ensures that the PM7001KI delivers a fast response time and a wide frequency range, resulting in crystal-clear highs and deep, rich lows.

The amplifier is equipped with a vast array of connectivity options. It includes multiple line inputs for additional components, a dedicated phono stage for vinyl aficionados, and a pre-out feature that allows for the connection of separate power amplifiers. This versatility ensures that the PM7001KI can seamlessly integrate into any audio setup.

In terms of build quality, the PM7001KI does not disappoint. It boasts a sturdy chassis designed to minimize vibrations, shielding the internal components from interference. The use of high-quality capacitors and a precision-engineered volume control further enhances the audio experience, providing cleaner, undistorted sound at any volume level.

Another notable technology employed in the PM7001KI is the innovative HDAM (Hyper Dynamic Amplifier Module) circuit, which replaces the conventional operational amplifiers found in many amplifiers. This technology improves audio performance by minimizing noise and increasing dynamic range, leading to a more engaging listening experience.

In summary, the Marantz PM7001KI Integrated Amplifier is a perfect fusion of power, precision, and versatility. Its dedication to exceptional sound quality, combined with a stylish design and comprehensive features, makes it an ideal choice for serious music lovers. Whether listening to classical, jazz, or rock, the PM7001KI ensures that every note is delivered with clarity and impact, staying true to Marantz's commitment to quality audio for decades.
