The MM7055 power amplifier produces 140 watts of high current output from each of its five channels.  This is “real world” power, too, measured across the full audio bandwidth (20 Hz – 20 kHz) at 8 ohms with 0.08% Total Harmonic Distortion.  Among other attributes, this means the MM7055 is capable of long-term power delivery into low impedance speakers.

 

A massive power supply includes a multiple-secondary EI-core transformer and over 65,000 µF of custom-designed energy storage capacity.  Critical circuit components from many world-class suppliers were chosen only after extensive listening tests.  Among these, the LAPT Hyper Power output devices were first used in Reference Series components.  Current feedback topology insures astounding accuracy and control under high-drive conditions.
