Powered by components meticulously chosen through three years of development, the Absolute Headphone Amplifier delivers fast, dynamic sound with superior headroom and delightfully punchy bass.
Manley's unique Variable Feedback control also allows users to alter the amount of negative feedback or ’tightness’ applied to the amplifier's output. Fully orchestrated arrangements with numerous instruments and aural elements may thrive in higher feedback settings, while a lone vocal uninhibited by percussive transients can enjoy listening intimacy with feedback rolled off.
The Absolute Headphone Amplifier features custom hand-wound air-gapped dual-mode IRON output transformers developed and manufactured in-house by the Californian manufacturer.
Catering to a wide and varied headphone market, the Absolute Headphone Amplifier’s transformers can also be switched across three output loads to satisfy headphones with impedances from 12 to 600 Ohms and even beyond.
Headphone listening is not new to us; we have been producing personal headphone playback systems aka 'Cue Mixers' for recording studios around the globe for well over twenty years. In the HiFi world, our legendary Manley Neo-Classic 300B Preamplifier has become a total cult classic with headphone listeners since the mid-1990’s. Reaching forward, we wanted to produce an extraordinary sounding headphone amplifier chock-full of features and sonic variety for the audiophile, at a price that wouldn’t break the bank either. I know you’re going to Absolutely LOVE this exciting creation of ours - EveAnna Manley (President, Manley Labs)
The Manley Absolute Headphone Amplifier is available in three colors, silver, copper, or black all with carbon fiber accents. The arched top chassis member is designed for resting ear pads and headband assemblies when headphones are not in use.
