Benchmark HPA4 Headphone Amplifier / Preamplifier Faceplate:Rackmount and a lookTHX AAA reduces harmonic, intermodulation, and crossover distortion by 20 to 40 dB to guarantee a realistic and fatigue free listening experience. It accomplishes this using a patented feed forward topology to null conventional distortion and noise mechanisms, resulting in the world's most linear amplifier. THX AAA allows the amplifier to reach its maximum output power and sound pressure level (SPL) without producing the distortion that normally
