LIVE, in-your-room clarity
The M2 is our latest implementation of state of the art fully analog power technology and highly refined music reproduction.
The M2 has a new FET input stage and an all new circuit board with additional circuitry which is not available in our previous versions or updates.
The M2 is a full complementary symmetry bipolar implementation and contains no coupling capacitors in the forward direction. It employs the latest technology in wide band output devices with enhanced low level linearity. Proper stage-to-stage impedance matching insures extraordinarily low distortion and a unique successive stage to output confluence provides a seamless combination of micro/nano-resolution from forward stages and robust controlled power and authority from successive stages. This unified current summation drive stage network eliminates the crossover notch problems common in many solid state amplifier designs. High idle current or class A bias output stage operation is not necessary! The M2 runs cool under most listening conditions and provides a live presentation with none of the hardness normally associated with solid state amplifiers. The output network of this amplifier is resonance free and remains stable even with a 1 micro-Farad capacitor connected across the output terminals. The M2 engenders the fine resolution and liquidity normally associated with tube amplification plus the power and bass control of solid state. Individual voices remain distinct and clear amidst the crescendo full orchestra and chorus. The sound of the M2 is pure and true to the source. It has the clarity, focus in time, and natural sound inherent in all Herron Audio products.
The M2 incorporates automatic low level d.c. offset cancellation plus high level d.c. shutdown speaker protection circuits. The effects of continuous low level d.c. at the input of the M2 will be nulled out over time and higher levels of d.c. at the input will engage the shutdown protection.
The M2 has an oversized toroidal transformer capable of supplying enough current to power two amplifiers with the ratings of the M2. This transformer is designed to have low losses and will run cool under all operating conditions.
