A true reference Pre-amplifier commissioned and specially designed by Roy Mottram from the U.S.A to compliment our mono block power amplifiers and Phono stage amplifiers.

As standard made using the most exotic of components and housed in beautiful hardwood cabinets, our MV1 valve pre-amplifier will compete with the very best products out there regardless of cost.
Again……listening is believing!!

Design specifications include dual mono power supplies with each channel supplied by it’s own high voltage and filament rails via a tube rectifier and feeding separate regulators to give incredible stereo separation.

A very simple but pure signal path based around the 6SN7 audio tube but upgraded to Black Treasure tubes and using a single output capacitor which can be specifically chosen for it’s integration to solid state or valve amplifiers based on input impedance compatibility.

MV1 features :

  • Dual mono design
  • Black Treasure vacuum tubes
  • Khuzmo 48 way stepped shunt attenuator using Charcroft Z foil series resistors
  • Dueland Coherent Audio internal wiring
  • Optional balanced output using Lundahl amorphous transformers
  • Solid hardwood cabinet construction for vibration isolation
  • Optional input configuration for single, dual or 4 inputs either balanced or single ended

Purity of signal path is critical in the design of any amplifier to give incredibly black backgrounds and the retrieval and portrayal of the tiniest musical passages and notes.

If you have never heard a valve based pre-amplifier of this class you will be amazed at how much information you may be missing in your vinyl or digital music collection.
