Our latest Preamplifier is a full tube line stage design using 4 x 12AX7 specially selected tubes.

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.

Volume is controlled via a Khuzmo 48 stepped attenuator  and series shunt resistor. No other manufacturer would use components such as this and many other parts as standard in a product in this price range.

MV3 features

• Khuzmo 48 way stepped attenuator as volume control
• Low ripple power supply on the anode
• R-type transformer
• Duelund Coherent internal wiring
• SE model upgrade to high end signal capacitors

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.

Standard model    £1600.00

SE model                £2000.00

A true reference Pre-amplifier to compliment our mono block power amplifiers and Phono stage amplifiers.

MV2 is entirely based around the MV1 but in a aluminium chassis and without some of the more exotic components and hardwood casework.

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
• Dueland 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.
