From the Bricasti web site:

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.

The M20 is a fully differential dual mono preamp powered by three linear power supplies, one for each of the analog sections and a separate supply for the digital control circuit processor to ensure isolation from the analog PCB and power supplies. So in this way the M20 is a full Class A design. The M20 comes complete with Stillpoints isolator feet.

The M20 includes 2 balanced XLR inputs/outputs and 1 unbalanced, RCA input/output. Pre-set channel naming conventions from the display can be uniquely customized through the menu as well as fine adjustment of level offset. The trigger-out mini-jack on the rear can be connected to the our power amps like the M28s or DACs like the M21 to send a 5V DC voltage trigger to power them in and out of standby from power off or standby on the M20
