Amplification in a class of its own

Features

Perfectly Balanced

Together with the GT-5000 turntable and C-5000 preamplifier,
Yamaha delivers an end-to-end balanced signal chain across its flagship models
for premier performance.

Designed to Perform

Meticulously designed, the M-5000 adopts a perfectly
symmetrical layout to isolate the left and right channels both physically and
electrically.

The deliberately simple design, which also serves to reduce
the signal path as much as possible, minimizes energy loss and achieves lower
impedance for high-fidelity performance.

Floating and Balanced Power Amplifier with MOSFETs

As opposed to conventional power amplifier designs whereby
power is supplied via a power transistor and the negative polarity is connected
to ground, the power supply of the M-5000 is connected directly to each
positive and negative side of the output stage.

Completely floating the entire power amp circuit from the
ground removes any undesirable impact of minute voltage fluctuations or ground
noise.

The design also creates an ideal symmetrical layout for
employing MOSFET power amplifiers, improving drivability for low impedance
speakers.

Rigid Frame Structure Featuring a Mechanical Ground
Concept

The M-5000 has been designed from the ground up to maximize
rigidity — reducing unwanted vibration for optimal sonic performance.

Further, employing a mechanical ground concept by fixing the
power transformer, block capacitors and heat sink directly to the rigid,
streamlined construction with bolts ensures they are fully supported and
eliminates the influence of vibrations.

Massive Toroidal Core Transformer and Low Impedance
Design

Delivering high-fidelity performance, a massive toroidal
transformer is utilized with a 3 mm-thick pure brass base which suppresses
unwanted vibrations.

In addition, the power transformer does not influence the
surrounding audio circuits due to less leakage flux.

The drawn-out copper wiring from the winding core
contributes to the low impedance design by markedly reducing the loss of energy
when compared to conventional designs.

Thick Wires and Screw-Type Connections for Power Supply

Thick wires and screw-type connections contribute to the
low-impedance design of the M-5000 — minimizing energy loss that would
otherwise typically occur in conventional connections and wire assemblies.

The use of screws and brass terminals directly on the block
capacitors as opposed to solder promotes a strong, low-impedance connection.

Custom-Designed Feet

All aspects of the M-5000 design were considered in
producing this flagship model. Its construction exudes master craftsmanship and
reflects an obsession with achieving the highest levels of performance.

The feet are no exception. Original in their design, the
heavy-duty brass feet function either as fully supported spikes or with a
scratch guard base for use on delicate surfaces.

Exquisite, Large Level Meters Reflect the Dynamics in the
Music

The M-5000 features large, high-precision meters on the
front panel, enabling audiences to visualize the dynamics of the music.

Measuring 7 mm-thick and made from Asahi glass, these
quality meters only enhance the luxurious and exceptionally elegant aesthetic
of the M-5000.

Premier Speaker Terminals

The M-5000 utilizes oversized, screw-type speaker terminals
to ensure ease-of-use and a secure connection. Cut from a pure brass block, the
original Yamaha design denotes a meticulous attention to detail and premier
quality.

The 3 mm-thick terminal base plate is also made from pure
brass for strength and rigidity, and assists in reducing distortion due to its
non-magnetic properties.
