Highest quality equipment
STEP 1
Based on a tri-concept philosophy combining ultra rigid construction, the best-in-class amplifier design and advanced digital processing, only the most select parts as well as cutting-edge Pioneer
technology are found in the VSA-AX10Ai-S. Highly stable, solid-grade materials create the ultra rigid construction for the highest sound clarity. In addition, top-performance components like
A.D.E. MOSFET are the secret to high-quality amplifier design. Finally, high-end advanced technology, like i.LINK, is responsible for high-quality digital audio transfers and advanced digital processing.
It is clear that the VSA-AX10Ai-S was designed with a quest for pure sound perfection.
Ultra rigid construction
Innovative frame design concept and concentrated direct
construction design for superior support
This revolutionary 3-D space frame construction reinforces the physical strength of
the amplifiers. Unlike traditional 2-D chassis designs, each part is fixed to the frame
from various angles, so the unit has the strength to support the heavy 10 kg
transformer, without any distortion. The double-layered chassis ensures an
extremely strong and rigid base for the 3-D frames. In addition, the chassis is copper-
plated to suppress signal interference between circuits and reduce ground
impedance. This 3-D space frame works simultaneously with the concentrated direct
construction to further minimise signal interference as well as reduce the signal
path. Each circuit is separated — allowing a more direct and extremely pure signal
route — which results in an open and fresh sound.
Stable cast iron base for ultimate chassis rigidity
Combined with the 3-D space frame, the
stable cast iron base realises heretofore
unknown chassis rigidity. The heavy 4 kg
cast iron base, made by TAOC — known
as the quality audiophile accessory
brand —, overwhelmingly enhances the
strength and stability of the chassis. And
it serves to support and intercept
external vibration thanks to its specially
designed material — 10 times more anti-
resonant than steel. The base contacts
the frame at 15 points with the newly
developed, patent-pending pivot-shape
for crystal-clear and even deeper bass
sound.
Unwanted vibrations reduced thanks to Transformer Stabiliser
To offer even more stability and rigid support for the heavy 10 kg transformer, an extra 2.0 mm thick steel stabiliser is
attached to the transformer frame. This carefully designed construction was implemented after thorough simulation by
advanced CAD (Computer Aided Design) technology. The chassis is prevented from causing unwanted vibration during
sound reproduction, ensuring maximum transparency of delicate audio signals.

High-quality amplifier design
7-channel Advanced Direct Energy MOSFET for solid high
performance audio
Pioneer's exclusive Advanced Direct Energy (A.D.E.) MOSFET produces an
amazingly efficient, high-end sound quality with an impressive 170 watts (DIN) of
equally amplified power for each channel, to ensure consistent sound quality for
AC/DC isolated
amplifier module
multi-channel applications. This highly advanced circuitry is designed to offer
high stability combined with low energy loss and ultra linear amplification. A new
AC/DC isolated amplifier module — designed especially to optimise the A.D.E. MOSFET performance under any condition —,
combined with the built-in temperature adjustment of the bias circuitry, regulates the drift of the bias point and minimises
power imbalances that can cause distortion in the sound stage.
7-channel symmetrical power train design for precise sound imaging
To balance electrical, physical and magnetic elements between the 7 channels for the most precise
sound stage reproduction, Pioneer designed each power amplifier symmetrically on each side of the
heat sink. This 'symmetrical power train' creates a uniform sound field for all channels.
Chimney-shaped heat sink for efficient heat dissipation and low resonance
Since this amplifier incorporates 7-channel, high power units, it generates a huge amount of energy. The
chimney-shaped heat sink acts as a natural cooling system, releasing excess heat from the power
elements which could otherwise adversely affect operation. As no cooling fan is needed, there is less
resonance compared to general cooling systems, and the sound remains transparent to the source input
signal.
High regulation power transformer for stable power supply
Pioneer has developed a state-of-the-art large power transformer, weighing in at 10 kg, to guarantee a
stable and superabundant power supply for each individual circuit. Designed for audio, this power
supply avoids S/N ratio degradation caused by any internal energy loss and magnetic leakage, and
reduces interference caused by vibration. Even at maximum volume, it delivers a constantly strong
current with low impedance.
Large capacitors for clean and stable power at all times
The VSA-AX10Ai-S uses two 33,000µF large capacitors, designed exclusively for audio, for extra stability
and instant response to large power swings. The low loss thick copper bus-bar, attached to the
capacitors, maximises the power transmission. The huge capacitors and bus-bar combined ensure clean
and smooth power delivery at all times, even during sudden surges and continuous high volume
demands.
