What's unique about the brand
Buckeye Amps is a hifi amplifier brand known for its field-switchable gain architecture, which allows users to choose between fixed-gain Hypex stages or Buckeye's proprietary buffer with Low/Medium/High settings. The brand's measurement-driven approach has resulted in "top 20" Signal-to-Noise and Distortion performance and verified 2-ohm drive capability. Buckeye emphasizes service-friendly design through its 2-year shipping-covered warranty, plug-and-play internal components for user replacement, and North American Computer Numerical Control-manufactured enclosures. The company is expanding beyond module assembly toward developing in-house integrated amplifiers from scratch.

Hypex NC252MP 2-Channel:
- Positioning: Entry-level stereo amplifier designed for small desktop setups and modest power requirements.
- Description: Features a single all-in-one NC252MP NCORE module with integrated SMPS delivering 250 watts per channel at 4 ohms with 0.0015% THD and 121dB signal-to-noise ratio. Compared to the NC502MP, it provides less power output (250W vs 500W at 4 ohms) and lower output current capability (18A vs 27A), making it suitable for efficient speakers in smaller rooms rather than demanding full-range systems.
Hypex NC502MP 2-Channel:
- Positioning: Mid-range stereo amplifier for large speakers and full-range systems requiring substantial power.
- Description: Uses a single NC502MP NCORE module delivering 500 watts per channel at 4 ohms with 0.0018% THD and 124dB signal-to-noise ratio, plus higher 27A output current capability. While it offers double the power of the NC252MP, it lacks the advanced features of the NCX500 such as selectable gain settings and the newer module technology that provides even lower distortion.
Hypex NCX500 2-Channel:
- Positioning: High-performance stereo amplifier representing the latest NCORE technology with advanced features.
- Description: Employs two separate NCX500 modules with external SMPS1200A700 power supply, delivering 700 watts per channel at 4 ohms with exceptionally low 0.0006% THD and 128dB signal-to-noise ratio. Unlike the integrated NC502MP modules, this design offers selectable gain settings, TI OPA1612 op-amp implementation, and significantly better distortion performance.
Hypex NC502MP 4-Channel:
- Positioning: Multi-channel amplifier for home theater front speakers or demanding surround setups.
- Description: Contains two NC502MP NCORE modules providing the same 500W per channel performance as the 2-channel version but across four channels for applications like front LCR speakers. Compared to using separate 2-channel amplifiers, this configuration offers space efficiency and cost savings while maintaining identical per-channel specifications, though it lacks the advanced gain control and superior distortion performance of the NCX500 series.
Purifi 1ET9040BA Monoblock:
- Positioning: Flagship monoblock amplifier representing state-of-the-art Class D technology for ultimate performance.
- Description: Features second-generation EIGENTAKT technology with bridge-tied-load configuration delivering up to 1400 watts at 2 ohms with an extraordinary 0.0001% THD and 140dB signal-to-noise ratio, plus massive 40A output current capability. Enhanced with Micro Audio SMPS1k-SN power supply providing active power factor correction, this monoblock surpasses all Hypex offerings in power output, distortion performance, and noise floor.
