Moon by Simaudio 870A Reference Stereo Power Amplifier

This is one of the BEST dual Mono Amps on Planet! Says Everyone :-)


Technology which eliminates feedback and
results in: Real-time amplification; More accurate musical
reproduction with respect to tonality; Non-existent transient
inter-modulation distortion; The elimination of phase errors
resulting from feedback.

Output stable to any known speaker impedance.

“Class A” power output to 5 watts for greater efficiency.

A high damping factor for superior musical dynamics,
improved signal speed and refined timbre accuracy.

Self-diagnostic system that detects both over-heating
and the presence of DC in the input signal.
