"Designed for music lovers, audiophiles have discovered they meet all of
their needs and then some. Almost amazingly, the powerful though small
and light weight power amplifiers are almost cool running though the
audio quality that comes closest is only from so called "Class A"
designs in my experience."

The Amplifier :

The M1A 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 M1A 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 M1A
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 M1A is pure and true to the
source. It has the clarity, focus in time, and natural sound inherent
in all Herron Audio products."

DC Response: The M1A 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 M1A will be nulled out
over time and higher levels of d.c. at the input will engage the
shutdown protection.

The M1A has an oversized toroidal transformer capable of supplying
enough current to power two amplifiers with the ratings of the M1A.
This transformer is designed to have low losses and will run cool
under all operating conditions.
