AUDIO-GD HE-9 MK3 Balanced Headphone Preamplifier / Amplifier Black

Audio-GD once again presents the quintessence of audio technology with its HE series products, here the HE-9 preamplifier and headphone amplifier, an evolution of the MASTER series. They have benefited from the longest design and testing period in the history of the famous brand. Although Audio-GD had already been studying the products since 2006, the brand's top technicians are now offering them to us in their most accomplished form, with outstanding performance. The MK3 version incorporates output buffers to improve the sound quality of the preamp, dual volume control to match the different output levels of your sources perfectly, and paired modules for the left and right channels for perfect sound coherence.

Audio-GD HE-9 MK3: Exquisite interior and connectors

This HE-9 has no fewer than 5 analogue inputs to meet every need: 2x RCA, 2x XLR and 1x ACSS, alongside 3 analogue outputs: XLR, RCA and ACSS. Not forgetting, of course, the headphone outputs on the front panel: XLR 4-pin and Jack 6.35mm, all two stereo.

Each Audio-GD product is scrupulously tested from every angle using one of the most powerful systems in the world: the Audio Analyzers 2700 Series from Audio Precision.

Audio-GD HE-9 MK3: Regenerative Power Supply

The HE series from Audio-GD features Regenerative Power Supply technology, which has undergone extensive testing and research to produce its current incredible performance. In particular, this technology uses a thick aluminium plate to separate the power supply circuits, a shield for the main power supply circuit and a design that limits the transmission of interference between the power supply and the audio circuits. The quality of this power supply system can be felt right from the first listen, with more detailed reproduction, greater dynamics, deeper bass and a wider soundstage. Furthermore, this technology also offers a more ‘analogue’ sound reproduction.
