Exposure XM3 Phono Stage


Notify me when back in stock

The Exposure XM3 phono-stage is based around a single circuit board that contains all power supply and audio circuitry. A 200VA toroidal transformer has been placed behind the front panel of the case with a small mains switching and filter board beside it. Eight pairs of capacitors are connected in parallel in the PSU section to achieve the necessary power supply smoothing capacitance. 

The chassis is solid and includes an aluminum front panel available in black or titanium finish. The XM3 has separate inputs for MM and MC cartridges and these are selected using a push button on the back panel.


  1. Large 200VA custom made toroidal transformer for power supply
  2. Multiple power supply capacitors in parallel for low ESR
  3. All discrete transistor audio stages
  4. High quality resistors & capacitors used in the signal path
  5. Separate MM & MC inputs selectable on the back panel
  6. Adjustable loading & gain switches on the back panel
  7. High-quality all-aluminum casework and extruded front panel
  8. Three-year guarantee
  9. Available in black or titanium
