Stunning 'Musical Fidelity X-AS100 Dual Mono Power Amplifier. A multi award winner from the now legendry 'X' component range from around the year 2000. Now deemed to be one of the best power amps at the time and now, for the money! Amazing build quality, of which was noted as being the reason why Musical Fidelity had to update it with the far inferior 'square' X component range! Amp is in exceptional order, comes with the original power supply and box (no instructions and internal packaging). Output power - 100 watts per channel into 8 ohms Frequency Response - 10hz-70hz = 1db Input ratio - 900mV.
