M2TECH Nash MC/MM Phono Preamplifier
The Nash is a dedicated preamplifier and phono equalizer for every cartridge model. It is provided with two phono inputs, one for low-level MC cartridges and one for medium-high level MC cartridges and MM cartridges.
Its FET-input, all-discrete components circuits feature vanishingly low noise and plenty of gain, allowing for a stunning 2.5Vrms output with 5mV on MM and 170uV on MC. The passive RIAA is implemented with high precision polypropylene capacitors.
MC interface paramenters (input impedance and MC pre-pre gain) are set by potentiometer from the rear panel. As well, MM interface parameters (input impedance and capacity load) are set by DIP-switches, again from the rear panel.
The Nash is provided with a Bluetooth BLE interface for control and configuration. An Android (and soon iOS) app will allow user to fully control the unit and set the configuration parameters. A comprehensive, continuously updated pickups database will make configuration faster and easier.
You control the Nash by the front panel encoder, using the remote control or by the dedicated Android app via Bluetooth. Operation data are displayed on a high readability OLED display. A menu allows for setting parameters like: anti-rumble filter, MM input stage gain, etc.
Two auxiliary line-level inputs make the Nash a hub or switching box for analog sources, an interesting add-on when the Nash is used together with the Young MkIII, to fully exploit the latter’s only analog input. A Young MkIII-Nash-based system may have a total of four analog sources: two phono and two line-level.
The Nash noise and sound performance can be further increased by replacing the stock wall adaptor with the Van Der Graaf MkII Low Noise Power Supply.
