NuPrime IDA-9 Review by PMA Magazine

Overview

NuPrime’s IDA-9 is a compact, 200Wpc integrated amplifier and DAC that impressed the reviewer with both build quality and performance. At US$1,549, it delivers exceptional value in today’s high-end audio landscape, combining a class-A input stage, a class-D power stage, and a GaN-based power supply with Active Noise Cancellation—a rare feature in any high-end product.

“Few, if any, high-end brands dare to incorporate GaN power supplies in their products… The IDA-9 features a NuPrime proprietary GaN power supply with Active Noise Cancellation—perhaps an industry first.”
— Robert Schryer, PMA Magazine

 

Design & Features

The IDA-9’s design is solid and tactile, with a sleek aluminum chassis and finely engineered controls. Two large knobs control input selection and volume, each providing a satisfying tactile click. The unit includes USB, coaxial, optical, and analog RCA inputs, with RCA outputs and an expansion port for Bluetooth or Wi-Fi modules. Its DAC supports high-resolution PCM up to 384 kHz and DSD256, making it versatile for CDs, hi-res FLAC, and PC-based streaming.

“The IDA-9 sounds as a whole—a cohesive piece of gear wherein all the parts were optimized to work seamlessly together.”
— Robert Schryer, PMA Magazine

NuPrime’s proprietary ULCAM class-A/class-D architecture combines the warmth and immediacy of class-A with the speed, efficiency, and power control of class-D. Despite doubling output compared to its predecessor, the IDA-9 runs cooler and more efficiently, making it practical for extended listening.

 

Sound Quality

Upon first listening, the reviewer noted exceptional transparency and detail, though initial sessions showed a slight lack of bass presence and harmonic richness. After break-in, the IDA-9 revealed its full capabilities: a balanced, engaging sound with tonally accurate instruments and a finely layered soundstage.

“The 9 delivered a thick yet pure, energized presentation full of vivid tone, long sustains, and delicate playing technique—I was swimming in sound.”
— Robert Schryer, PMA Magazine

Classic recordings demonstrated the amplifier’s strengths: Neil Young’s vocals on Decade sounded natural and human, with instruments anchored in space and rich in timbre. Jazz recordings like Charles Mingus’s Changes One revealed harmonic depth and weight, with the double bass, drums, and piano fully articulated.

The IDA-9’s DAC also impressed, delivering hi-res streaming playback that enhanced instrumental texture, imaging, and soundstage depth.

“I could hear more into the materials of the instrument. The soundstage also seemed to expand inward, filling the room, while imaging and tones snapped further into focus.”
— Robert Schryer, PMA Magazine

The reviewer found no need for external DACs; the IDA-9’s internal conversion performed irreproachably, preserving the musicality of the system as a whole.
