Marantz PM8004 review
More natural music reproductionThe refined array of circuit innovation
inside the PM8004’s chassis are all devoted to one goal – more natural
music reproduction. Flexible EqualizationOne of the first things you’ll
notice about the PM8004 is the front panel’s TriTone tone controls.
Tri-Tone adds a midrange control to the more conventional bass and treble
adjustments. Tri Tone actually dates back to Marantz’s 1954 Model 1
Preamplifier and is even more useful today to correct frequency imbalances
that often characterize compressed music sources such as iPods.A Solid
Foundation - Power Supply and Parts SelectionSpecified by Marantz
engineers, a large torroidal transformer is the foundation for the
PM8004’s power supply. Its circular shape and double shielding helps
control stray magnetic fields that could adversely affect sound qualityThe
PM8004 also benefits from a wide array of parts carefully selected only
after extensive laboratory evaluation and listening-room audition. This
process, call Sound Tuning, assures you of optimal performance.High Current
AmplifierThe 70 watts per channel (8 ohms) amplifier section delivers high
instantaneous current so musical peaks retain their full dynamic range.
The PM8004’s mechanical and electrical aspects are designed to minimize
the length of power supply lines and their potential interference.
Individual power supply segments are located on the same heat sinks as the
output transistors. The benefit is that the PM8004 responds instantly and
crisply to musical transients that lesser amplifiers would simply
blur.Short Signal Paths for Clearer SoundFor critical listening, the PM8004
includes a “Source Direct” switch that bypasses balance and tone
control circuits for pristine reproduction.Easily Integrates into Your Home
Theater SystemPower Amp Direct allows you integrate a dedicated 2 channel
Hi-fi system with your home theater receiver and easily switch between
modes. A convenient front panel switch optimizes the main-in terminals for
use with a separate surround processor so you can enjoy the same Left and
Right speakers you use for stereo. This switch also disables the
PM8004’s front panel controls (input selection, volume, balance, etc.) so
that the surround processor acts as the control center when you’re
enjoying surround sound. Another three-second push on the Power Amp
Direct button restores the PM8004 to normal stereo operation.Audio
Circuitry Designed for Superb ListeningBoth preamp and power amp sections
use fully-discrete, high speed current feedback circuits for minimal phase
shift and better detail resolution. The phono input is a fully discrete,
constant-current design optimized for moving magnet phono cartridges.Hyper
Dynamic Amplifier ModuleMarantz’s notable HDAM® SA3, the most recent
addition to the Hyper Dynamic Amplifier Module series, performs critical
stage-to-stage signal transfers that leave the music unaffected. 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. Even the Record Out terminals are
buffered for enhanced recording clarity.Beautiful Appearance, Functional
DesignThe PM8004’s 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. Aluminum front panel
knobs add solidity while the high precision motorized volume control
responds instantly to both touch and the PM8004’s included remote
control.As a proper foundation for the PM8004’s feature-rich performance,
the chassis itself includes a triple-layer bottom plate to insure long-term
alignment and vibration control.Attention to DetailOther details, those
affecting both connectivity and convenience, add to the PM8004’s
appeal. Rear panel speaker connectors, for example, are Marantz-original
heavy duty designs ideally suited for use with audiophile speaker cable.
With A/B speaker connectors and a front panel switch, you can select
speakers in two different locations. Other rear panel input and output
terminals are gold-plated for long-term corrosion resistance and better
conductivity.In SummaryIn short, the Marantz PM8004 provides exceptional
music reproduction for the most discriminating listener. And it doesn’t
short-change the home theater enthusiast, either. And for rack mounting,
the RMK8754MSP will be available shortly.For operational and technical
