11/20/2023 0 Comments Benchmark headphone amp![]() This means that the AHB2 clips with a 22 dBu input instead of an 8.2 dBu (2 V RMS) input. Gain is only 9 dB instead of the more typical 20 to 30 dB gain found in most power amplifiers. Output Noise < 2. Benchmark chose to build the amplifier with very low gain. Featuring the flagship THX-888 amplifier design, the revolutionary HPA4 headphone amplifier (SILVER) incorporates the same THX AAAtechnology that Benchmark uses. 3 dB Bandwidth exceeds 0.1 Hz to 500 kHz To make this all happen, the HPA4 includes a total of 64 precision relays.įrequency Response - 0.003 dB at 10 Hz, -0.001 dB at 20 kHz The HPA4 includes 4 independent 256-step attenuators: two for the L&R headphone outputs, and two for the L&R line outputs. No other relay gain control offers this level of precision and performance. Relay closures are precisely timed to deliver silky-smooth volume changes. Manufacturer : Benchmark Model : DAC3 HGC Serial Number : 20532249. The gain control has 256 steps in 0.5 dB increments. Benchmark DAC3 HGC DAC/Headphone Amplifier/Pre Amplifier Silver. The dynamic range of the AHB2 is 132 dB, making it 10 to 30 dB quieter than some of. Benchmark's AHB2 power amplifier delivers musical details without introducing the masking effects of amplifier noise and distortion. The line amplifier incorporates the finest gold-contact relays available. The AHB2 is the ideal match to the performance limits of High-Resolution-Audio (HRA) formats. The THX-888 amplifier is driven by a Benchmark line amplifier that features relay gain control, relay input selection, and relay muting. The HPA4 delivers power, audio fidelity, speed and accuracy over an utterly silent background. Hear the music without any contamination from electronic noise or distortion. THX AAA allows the amplifier to reach its maximum output power and sound pressure level (SPL) without producing the distortion that normally accompanies increased output levels in traditional amplifiers.įeaturing the flagship THX-888 amplifier design, the revolutionary HPA4 headphone amplifier incorporates the same THX AAA technology that Benchmark uses in the AHB2 power amplifier. It accomplishes this using a patented feed-forward topology to null conventional distortion and noise mechanisms, resulting in the world's most linear amplifier. Benchmark calls the HPA4 a reference stereo headphone amplifier and reference line amplifier, and I found no reason to dispute this. THX AAA™ reduces harmonic, intermodulation, and crossover distortion by 20 to 40 dB to guarantee a realistic and fatigue-free listening experience. ![]() have partnered to introduce the Benchmark HPA4 headphone/line amplifier featuring THX Achromatic Audio Amplifier (AAA™) technology. The HPA4 is Benchmark's newest headphone amplifier. HPA4 - BENCHMARK'S FLAGSHIP REFERENCE HEADPHONE AMPLIFIER
