I'm the second owner of this unit, in excellent condition. Rated 8/10 due to 2 very small nicks on the unit (see photos). The unit is an original K-1xe and it has the only available upgrade, which is a new regulator for the stepper motor. This is the line stage version which doesn't have a phono stage. Ayre confirmed this unit never had any issues.
The remote is machined metal and feels great in your hand. Ayre replaced the remote for me so it is mint. Unit has been in smoke free house. The Ayre design has a separate power supply, separated from the main unit by about 10 feet so you get no issues from having power supply close to other components. Includes original owners manual. Power cord included. Original box. Recently upgraded my pre-amp and amps (went with Ayre MX-R amps).

Conceivably the most innovative preamplifier ever designed, the Ayre K-1xe combines singular transparency with unparalleled musicality. Musical passages emerge with startling dynamics from a silent background, thanks to the K-1xe’s fully-balanced, zero-feedback FET circuitry. Its unique volume control uses solid-silver contacts in a revolutionary configuration that eliminates all wiring and takes sonic performance to a new level. The Ayre K-1xe uncovers the soul of music.
