KX-8 Variable Gain Preamplifier

First appearing in our world famous KX-R preamplifier, the KX-8 features the same recipe for true variable gain volume control; although in a much simpler and cost effective approach. Maintain a constant signal to noise ratio and set the music free, at any volume level. Built around Ayre’s exclusive innovations, the Ayre KX-8 includes fully-balanced, true zero-feedback circuitry throughout for natural musicality, unprecedented dynamics and detail.

The KX-8 Preamplifier allows users to customize to their needs, by allowing a set of optional standard digital inputs, and optional USB or Network inputs, making it amazingly versatile. Featuring up to eight az inputs (Ethernet, USB, AES/EBU, S/PDIF (2), and Toslink (3)) and five analog inputs (2 Balanced, 3 unbalanced) it’s prepared to be the analog and digital hub for most any systems. With the Ethernet module installed, it is Roon-ready and pre-configured to stream Spotify, Qobuz, and Tidal. The KX-8 will unlock the potential of your source components, and your power amplifier; becoming another timeless classic in the Ayre Acoustics heritage.

The KX-8 stands to be one of our greatest headphone experiences to date. Taking full advantage of the true Variable Gain volume control and true zero feedback design throughout, both balanced and unbalanced front panel connectors–driven by Ayre’s exclusive Diamond amplifier circuit will effortlessly drive the most demanding headphones, allowing music to flow effortlessly into your life. A first for our headphone users to be able to experience the the benefits of Variable Gain technology.
