MV2
MV2 Pre-Amplifiers Description Our flagship reference Pre-Amplifier to compliment our mono block power Amplifiers and Phono Stage Pre-Amplifiers. As standard hand made using very high quality components in the signal path, our MV2 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 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. MV2 features: Dual mono design Tung-Sol vacuum tubes upgradable to Black Treasure or Pavane Khuzmo 48 way stepped shunt attenuator Duelund Coherent Audio internal wiring Miflex paper/oil output capacitors 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.

MV3
MV3 Pre-Amplifiers Description Our latest Masterpiece edition MV3 elevates the current high standard of tube pre-amplifiers with a design that uses Mundorf silver/gold in oil signal capacitors and Amtrak’s carbon film resistors in the signal path. High specification power supply capacitors, silver internal wiring and selected NOS vintage tubes bring added soundstage and reality to recordings. MV3 follows in the footsteps of the incredible MV2 using the same principles of minimum of active parts and high quality passive components in the signal path. A no compromise design and attention to components and internal wiring brings a product worthy of the Robson brand and a great match to our range of power amplifiers. MV3 features Blue Alps Swiss volume control Low ripple power supply on the anode Vintage tubes Duelund Coherent internal wiring Masterpiece edition with upgraded signal capacitors and resistors Great design and the use of very high quality components has created a pre-amplifier of exceptional abilities and able to drive the most difficult of power amplifier loads to below 10Kohms.

Masterpiece Edition Pre-Amplifier
Masterpiece Edition Pre-Amplifier Masterpiece // Pre-Amplifiers Description Designed around the MV2 Pre-Amplifier but taken to a completely new level in terms of component specification, vacuum tube choice and internal wiring to give an even better sense of musical involvement and resolution. The Masterpiece Edition Pre-Amplifier has an extremely simple and pure signal path with only 1 output capacitor and 1 shunt resistor on the Khuzmo stepped attenuator which have been replaced with the incredible V-cap CuTF reference capacitor and a Charcroft Z foil resistor. This along with 5N solid silver and FEP fluoropolymer signal wiring gives this Pre-Amplifier added realism and an even better 3D soundstage capable of competing with the very best equipment in the world. The choice of Linlai Global Elite vacuum tubes also elevated the sound field beyond the previous Black Treasure tubes. 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. Bespoke designs available on request.
