MARANTZ - PM 8003 INTEGRATED AMP

Marantz builds the ultimate affordable audiophile integrated amp, the PM 8003! 

Marantz has built a winner with the PM 8003 integrated amp!  Designed from the ground up as a world beater, the PM 8003 is built to deliver more music per dollar than any integrated Marantz has ever made.  Powerful, resolving and sweetly musical, the PM 8003 is a listener's amplifier, creating an irresistible sonic experience.

Every aspect of the PM 8003 exudes quality, both sonic and aesthetic.  From the enormous double shielded transformer and custom created binding posts to the gorgeous new alloy faceplate, the PM 8003 is destined to become another Marantz classic.

In both the preamp and power amp sections, the PM 8003 uses fully-discrete, high speed current feedback circuits for minimal phase shift and better detail resolution.  Even the phono input, normally a low quality after-thought in some competitor’s offerings, is a fully discrete, constant-current design optimized for moving magnet phono cartridges.  Another discrete implementation – this time of Marantz’s notable HDAM® SA3 (the most recent addition to the High Definition Amplifier Module series) – performs critical voltage to current conversions throughout the PM 8003. Most inputs benefit from a common buffer circuit that minimizes unwanted interactions between source and amp.  The CD input enjoys a separate buffer for even better isolation.  The amplifier section in particular is optimized for high instantaneous peak current capability.  This involves both a mechanical and electrical redesign of previous approaches to minimize the length of power supply lines and their potential interference.  The resulting amplifiers boast individual power supply segments mounted on the same heat sink extrusions as the output transistors themselves.  An advantage is the ability to make the power supply traces wider and more efficient but the real benefit is the PM 8003’s ability to respond instantly and crisply to musical transients that lesser amplifiers would simply blur.  

For even more fastidious listening, the PM 8003 includes a “Source Direct” switch that bypasses balance and tone control circuits.  And the Record Out terminals sport their own buffer for enhanced clarity with your choice of recording devices.  

In the PM 8003, even the pre-out/main-in terminals serve an additional purpose.  A convenient front panel switch optimizes the main-in terminals for use with a separate surround processor and disables the PM8003’s front panel controls (input selection, volume, balance, etc.).  Another three-second push on the Power Amp Direct button restores the PM 8003 to normal stereo operation.  

The front panel uses a carefully chosen combination of aluminum and glass-reinforced resin to create a distinctive three dimensional appearance. Indirect reflecting blue LEDs indicating input selection, etc., heighten that elegant appearance.  Small details, those affecting both connectivity and convenience, add to the PM 8003’s appeal.  Rear panel speaker connectors, for example, are Marantz original designs.  Rear panel input and output terminals are gold-plated for long-term corrosion resistance and better conductivity.  Aluminum front panel knobs add solidity while the high precision motorized volume control responds instantly to both touch and the PM 8003’s included remote control.  As a proper foundation for this performance- and feature-rich component, the chassis itself includes a triple-layer bottom plate to insure long-term alignment and vibration control.  

In short, the Marantz PM8003 provides exceptional music reproduction for the most discriminating listener.  And it doesn’t short-change the home theater enthusiast, either.  Would you expect any less from Marantz?
