Update Notice

Standard version updated on October 26, 26: The buffer level design has been updated, and both levels of buffering can be selected
through jumper caps. The first level is the onboard OPA1656 buffer level, which is loaded by default, and the second level is
DIP8, which is empty by default. Please note that this setting is not missing, giving players maximum configuration freedom.

Sep 14, 2025: The Luxury Edition NCx500/1ET6525SA linked here will no longer come standard with WBT connectors. Their primary value lies in brand prestige rather than a decisive sonic difference. They are replaced by rigorously selected, high-quality pure copper speaker terminals with thick gold plating, ensuring conductivity and mechanical reliability with minimal practical listening difference. This change significantly reduces the product's retail price while maintaining sound quality and reliability, lowering the entry barrier for the Luxury Edition and making it more accessible for enthusiasts to experience its sound. We will still offer WBT or other high-end connector upgrades for users with specific preferences—please contact customer service for this request. Please note: Luxury Edition images are being updated gradually; specifications at the time of order on the product details page prevail.
Â
Sep 8, 2025: Modified the buffer-stage op-amp for the Standard Edition; it no longer ships with MUSES O2 and now defaults to TI OPA2828. The Standard Edition includes an upgraded linear power supply for the buffer stage.
Â
Dec 24, 2024: Added new PURIFI products: Standard and Luxury Editions featuring the original 1ET6525SA module (2-channel). Updated the RCA input section to address potential noise floor issues, increased RCA gain, and optimized RCA sound quality. Compared to similar products in its class, it's rare for a Class D power amplifier to retain and continuously optimize RCA inputs.

Maroon Audio Dual-Channel Power Amplifier is based on the genuine, cutting-edge Class D modules from Purifi (1ET6525SA, 1ET7040SA) or HYPEX (NCx500), delivering ultra-dreamlike THD+N and IMD specifications and superior listening experience.

All Maroon Audio power amplifiers are powered by genuine imported high-quality HYPEX (Netherlands) audio-specific switch-mode power supplies. The compact chassis (34cm deep * 33cm wide * 7cm high) provides formidable power per channel: 200W / 220W / 380W into 8 ohms.


Due to the specific requirements and standards for power cables and signal cables in Hi-Fi audio, the product does not include power or signal cables; they need to be provided separately.
