Benchmark HPA4 Headphone and Line Amplifier
Benchmark HPA4 Headphone and Line Amplifier
Hailed as the world’s Ultimate Line Amplifier, HPA4 is the product of a collaboration between Benchmark Media Systems and THX Ltd. It is the first headphone and line amplifier to feature THX’s Achromatic Audio Amplification technology (or AAA) and reduces harmonic/intermodulation/crossover distortion by up to 40dB. The reduction is achieved by utilising a patented feed-forward topology which nullifies conventional distortion and noise mechanisms.
With HPA4, Benchmark and THX have produced a headphone and line amplifier capable of technically reaching maximum output and SPL without the usual side effect of distortion, delivering power, audio fidelity, speed and accuracy onto a silent canvas.
