Bricasti’s 'Classic Series’ M21 is a natural evolution of both the M1 Special Edition and M12 Dual Mono Source Controller models. Sporting incredibly advanced architecture, the M21 can select up to three independent digital-to-analogue paths: 24 bit delta sigma, 20 bit ladder dac and true 1 bit DSD for all DSD content.

All digital input types are supported, and a direct output is available along with hardwire bypass functionality to skip the M21’s analogue attenuator circuit.

M21 connects seamlessly into any home network as a powerful media renderer, recognisable as a DNLA device and capable of transmitting pristine, long distance data with no loss or degradation of signal.
