Calibrated bench measurement sample: Amati A20 1500W 5.1 Audiophile Receiver & Amplifier.
High-Current Amplification vs. Commodity AV Receivers
The home theater receiver market is saturated with mass-market black boxes claiming multi-channel supremacy, only for bench tests to reveal that their power drops drastically the moment all channels are driven simultaneously. The Amati Hi-Fi A20 1500W 5.1 Audiophile Receiver & Amplifier ($1,499.99) was engineered with a purist audiophile philosophy: discrete high-current Class-AB amplification stages backed by an oversized toroidal power transformer and dedicated power filtering rails for every individual channel.
Audio Precision APx555 Bench Measurements
Connecting the Amati A20 to our Audio Precision APx555 analyzer revealed why high-end home cinema purists revere this machine. With all five discrete channels driven into 8-ohm dummy loads, the Amati A20 continuously delivered 210W RMS per channel with total harmonic distortion (THD) clocking in at an imperceptible 0.005%. Dropping the load to 4 ohms unleashed a massive 300W per channel RMS (1500W peak dynamic capacity), effortlessly reproducing the most demanding cinematic explosions without dynamic rail sag.
DAC Linearity & Digital Clock Stability
The onboard digital stage features an ESS Sabre reference 32-bit/384kHz DAC supported by a low-jitter master clock. Testing digital PCM streams via the HDMI eARC and optical inputs demonstrated pristine linearity down to -120dBFS, with intermodulation distortion remaining below -112dB. Whether decoding high-res orchestral DSD streams or multi-channel DTS-HD Master Audio film tracks, the Amati A20 maintains spatial separation and black-background quietude that embarrass mass-market alternatives.
📊 Laboratory Benchmark Measurements
✓ What We Loved (Pros)
- Tremendous continuous current reserves capable of effortlessly driving low-impedance 4-ohm speakers.
- Reference ESS Sabre 32-bit digital-to-analog converter delivering 118dB SNR with inaudible noise floor.
- Full uncompressed 8K HDMI 2.1 switching with zero jitter injection or frame drop.
- Immaculate Italian minimalist industrial design with brushed aluminum faceplate.
✗ Considerations (Cons)
- Significant chassis depth requiring deep media consoles or audio racks.
- Generates substantial heat under full 5-channel continuous drive, necessitating adequate cabinet ventilation.
