The Bricasti Design – Model 20 Preamplifier

Available in Platinum and classic black finish, the M20 Series dual mono preamplifier builds on the analog design of the M12 dual mono source controller to deliver a rich analog experience with fluid, fast and tonally balanced audio. The M20 Features fully differential and independently buffered signal paths for superior isolation and purity of sound. A proprietary, all discrete resister ladder attenuator, ceramic circuit boards and three dynamic Class A linear power transformers create the ultimate platform for your audio system.


Reference tone

The attenuator is a discreet ladder of digitally controlled resistors in 1dB steps utilizing Vishay foil resistors in key locations in the circuit; we find them to have a unique sound so we employed them to impart a tonal character to the M20, and PCB material is made from ceramic materials with excellent dialectic properties. The final output buffers are a proprietary discreet design and level control is accomplished using a R2R ladder technique allowing for perfect balance and tonal character at any level with recall, programmable input offset and remote control capabilities.

Heart of your system

There are three separately buffered analog outputs, two balanced one unbalanced. The output buffers are our own discreet design that is based on our other products like the M1, M12 and M21. All signal switching and hard output mutes are done using logic controlled relays. With 3 separately buffered outputs the M20 is ideal for bi amp applications with two balanced outs to drive two power amps or running two or three zones.
