Description
Building on the legacy of the award-winning IDA-8 — honored with two Product of the Year Awards and a coveted
Golden Ear — the NuPrime IDA-9 takes this iconic hybrid Class A+D amplifier to new heights. Retaining the IDA-8’s
spacious, transparent, and luxuriously textured sound, the IDA-9 doubles the amplifier’s RMS output power while
maintaining the same compact form factor, delivering an even more dynamic, effortless, and refined listening
experience.
www.nuprime-x.com
8
The IDA-9 is designed around the proven IDA-8 architecture with significant enhancements throughout. Its refined
Class A input stage and upgraded Class D switching MOSFET circuit now operate at 600 kHz, enabling high-resolution
audio performance while running cooler and more efficiently — reducing operating temperature by 30% for greater
headroom and natural sound reproduction. NuPrime’s revolutionary ultra-low-noise GaN power supply employs a
dual-phase interleaved GaN Power Factor Correction circuit, an advanced topology that ensures smoother power
delivery and minimal ripple current compared to traditional single-phase designs. Beyond the PFC stage,
new-generation GaN semiconductor modules drive a symmetrical dual supply system that provides balanced positive
and negative voltage rails for the amplifier’s differential circuit. Together, these twin GaN power blocks deliver a total
of 500 watts with peak current capability of 20 amperes, supporting an impressive 200 watts (RMS) per channel of
dynamic music power at 8 ohms. This GaN-based power architecture achieves unmatched thermal efficiency and
ultra-clean power delivery, producing a deep black background, exceptional channel separation, and breathtaking
clarity.
The result is a sound that’s neutral yet rich in detail, with excellent layering, tight bass, and an open, extended high
end — all while preserving the IDA series’ signature compact elegance and setting a new benchmark for modern
integrated amplifier design.

15
At the heart of the IDA-9’s power supply architecture lies a sophisticated dual-phase interleaved GaN Power Factor
Correction (PFC) circuit. This innovative design approach delivers exceptional voltage regulation while maintaining
minimal noise levels and achieving ultra-high efficiency. The entire PFC module is housed within a remarkably
compact 75 × 30 × 25 mm enclosure, yet delivers an impressive 600 watts of output power.
The dual-phase interleaved topology represents a significant engineering advancement, allowing for smoother
power delivery and reduced ripple current compared to traditional single-phase designs. This results in cleaner
power conversion and improved overall system performance.

Gallium Nitride High Frequency High Efficiency Power Module (GaN HFHFPM)
Beyond the PFC stage, the IDA-9 employs new-generation GaN semiconductor modules for the critical power
conversion stages that supply the amplifier circuits. These modules showcase the remarkable capabilities of GaN
technology, with each individual module maintaining the same compact 75 × 30 × 25 mm footprint while
delivering up to 250 watts of output power and instantaneous peak current capabilities of up to 10 amperes.
The choice of GaN semiconductors over traditional silicon-based solutions enables this extraordinary power
density while maintaining excellent thermal characteristics and switching efficiency. This translates to reduced
heat generation and improved long-term reliability.

17
Symmetrical Dual Supply Architecture
Engineering Excellence Through Miniaturization
The IDA-9’s power supply design incorporates two independent GaN power blocks configured to create a
symmetrical dual supply system, providing both positive and negative voltage rails. This balanced approach
ensures optimal performance for the amplifier’s differential circuit topology.
Combined, these twin power blocks deliver a total output of 500 watts with peak current capability reaching 20
amperes. This substantial power reserve enables the IDA-9 to achieve an impressive 200 watts per channel of
music output power, ensuring dynamic headroom for even the most demanding musical passages.
Perhaps most remarkably, this advanced power supply system delivers performance equivalent to traditional
transformer-based power supplies while occupying only one-fourth the physical space and weighing merely 20%
of conventional designs. This dramatic reduction in size and weight opens new possibilities for amplifier design
and placement flexibility without compromising performance.
www.nuprime-x.com
Performance Benefits
The integration of GaN Power Factor Correction with GaN Power Modules creates a synergistic effect that delivers
multiple performance advantages. The system achieves exceptional efficiency with minimal energy loss, translating
to reduced operating costs and environmental impact. The high power output capability within such a compact form
factor represents a paradigm shift in power supply design philosophy.

From an audio perspective, the GaN-based power supply contributes to the IDA-9’s sonic signature through fast,
detailed, and dynamic sound reproduction. The ultra-clean power delivery creates a deep black background that
enhances musical detail retrieval and provides excellent channel separation, allowing listeners to experience music
with exceptional clarity and precision. The NuPrime IDA-9’s GaN power supply technology represents a convergence
of advanced semiconductor engineering and audio design philosophy, delivering a solution that pushes the
boundaries of what’s possible in compact, high-performance amplifier design.
