Purifi and Hypex Class-D Power Amplifiers
Power, clarity and control for systems that deserve a serious amplifier.
Maroon Audio builds finished stereo and multichannel power amplifiers around genuine Purifi and Hypex modules, with original chassis layout, signal-buffer implementation, power integration, wiring, assembly and final test.
Choose by system
Start from the system you are building.
Two-channel music systems and multichannel theaters ask different questions. Maroon Audio keeps the route simple: choose the system, then choose the module platform.
Stereo Hi-Fi
Two-channel power amplifiers for music systems, DAC-direct setups and preamp-based Hi-Fi systems.

- NCx500 multichannel configurations
- M9040-3 Purifi three-channel configuration
- Build details confirmed before payment
Choose by platform
Purifi refinement or Hypex drive, built as complete amplifiers.
The module is the starting point. The finished amplifier still depends on layout, input stage, power integration, wiring, chassis work and final setup.
Purifi Platform
Amplifiers based on genuine Purifi modules, including the 1ET9040BA and 1ET6525SA platforms.
Hypex Platform
Amplifiers based on genuine Hypex modules, including NCx500 stereo and multichannel configurations.
Why it matters
Class-D should deliver control, scale and musical engagement, not just numbers.
Our goal is not to turn strong modules into a parts list. Through system architecture, signal-buffer work, power and interface integration, wiring, assembly and final tuning, we make them behave like complete amplifiers with clean background, stable grip, dynamic scale and a more engaging sound.
Headroom
Clean reserve for demanding speakers, dynamic movie passages and music that needs scale without strain.
Control
Fast, stable grip in the low end with a quiet background and clean system integration.
Tuning
A complete-amplifier tuning approach built around credible modules, careful wiring and implementation choices, aiming for clarity, density, layering and natural musical expression.

OEM amplifier manufacturing
Finished-amplifier OEM manufacturing around Purifi and Hypex platforms.
Maroon Audio is an important OEM customer for Purifi and Hypex module platforms, building finished amplifier products around their genuine OEM modules. In this category, we operate at a leading mainland-China scale in module procurement and finished-amplifier delivery. All OEM modules used in our builds are brand-new, genuine first-source units. We do not use clone modules, recycled modules, or uncertain-source amplifier boards; respecting engineering work and intellectual property is part of the product cost we choose to carry. Our design work focuses on overall system architecture, expanded feature implementation, signal-buffer optimization, power and interface integration, assembly consistency, final testing and complete-amplifier sound tuning, turning excellent module platforms into stable, deliverable power amplifiers with stronger real-system performance.
Before ordering
The practical details are kept visible.
We want the buying path to be clear before payment: voltage, shipping, duties and warranty are part of the decision, not fine print after checkout.
Voltage
Products are preset for 110V or 220V input before shipment. They do not support automatic voltage switching.
Shipping and duties
Fixed shipping is calculated at checkout. Import duties, VAT/GST, customs clearance, brokerage fees and local taxes are the buyer’s responsibility.
Warranty
Overseas orders include a 2-year warranty for the complete amplifier under normal use.
