The Nash Rev.b is a dedicated preamplifier and phono equalizer for each pickup model. It features two phono inputs, one for low-level MC phono cartridges and one for medium-high level MC phono cartridges and MM phono cartridges.

Its totally discrete component circuit with J-FET input is characterized by very low background noise and high gain, allowing it to reach an output voltage of 2.5 Vrms with 5mV on MM and 170uV on MC. Passive RIAA is implemented with high-precision polypropylene capacitors.

The MC interface parameters (input impedance and MC pre-pre gain) are set via the potentiometer from the rear panel. The MM interface parameters (input impedance and capacitance load) are also set by dip-switches, again from the rear panel.

The Nash Rev.b can be controlled with the front panel encoder and using the included infrared remote control. A menu allows user to set parameters such as: anti-noise filter, MM input gain, etc.

Two line-level auxiliary inputs make the Nash a hub or switching box for analog sources, an interesting plus when the Nash Rev.b is used together with the Young MkIV or other equipment equipped with only one analog input, to take full advantage of the unique analog input available. A Young MkIV Rev.b and Nash based system can have a total of four analogue sources: two phono and two high level (tuner, recorder…).

The noise and sound performance of the Nash can be further increased by replacing the included switching wall power supply with the M2Tech Van der Graaf MKII ultra-low noise power supply.
