The Musical Fidelity M8Xi is a separate preamp with two monobloc power amps sharing a common chassis. Each has its own heat sink and separate transformer. Genuinely dual mono. The preamp has its own separate power supply and is mounted close to the input sockets. Consequently, PCB tracks are very short. This elegant idea ensures that both channels signals are ultra low impedance the instant they get into the amplifier. This is a significant detail. Each channel has twelve big bipolar transistors – 200 amps peak to peak is easily available. The metalwork is high quality. The front panel is a custom made fine line extrusion of milspec aluminium. The custom made heat sinks have outstanding dissipation characteristic and finish. The M8xi construction has the feeling of solidity and quality.
