Decided to stick with my Krell for home theater, though this amp is more musical and has somewhat a more extended and sweeter top end. This is the best home theater amp Marantz has made, better than the 2 & 5 channel series below it as it has a copper bottom chassis, better toroidal (vs EI) transformer, among other things.
Far as I can tell almost identical to the current MM8077 but with 8 channels vs 7 and a slightly different faceplate. Both that & this amp retailed for $2400. Audiogon asking prices are $1100 - $1200. I'm asking $100-200 less & giving my AC buddies first crack before it goes on USAudiomart, Audiogon, etc.
It's in mint condition with the original box, power cable, manual and even RC code cable. I can ship USPS, UPS, and Fedex (preferred). Buyer pays shipping at actual cost. Estimated shipping weight is 43lbs.
Paypal preferred & no cost if sent as gift. Other forms of payment considered. Can ship overseas, but US buyers get first preference.
A google search will come up with lots of information and positive reviews, below is some information I've pulled.
Any other questions, please feel free to ask.

The Marantz MM8003 Power Amplifier – Multi-Channel Power AmplifierAs a stand-alone multi-channel power amplifier or the perfect complement to the AV8003 preamplifier/processor/tuner, the MM8003 provides Marantz-level performance to power the most advanced A/V systems. Eight channels. A massive power supply. Output devices from our renowned Reference products. Easy connectivity. Flexible, configurable operation. Multi-channel has never been this easy. Or this good. What else would you expect from Marantz?
140W x 8ch (8 ohms) Power Amplifier

In-Wall Subwoofer IncludedThe MM8003 power amplifier produces 140 watts of high current output from each of its eight channels. And this is the "real deal", measured across the full audio bandwidth (20 Hz – 20 kHz) at 8 ohms with less than 0.08% THD! In practical terms, this makes the MM8003 an ideal amplifier for a "7.1" system even if that system includes a high quality passive "in-wall" subwoofer. Alternatively, you can opt for stereo output to each of four different rooms and turn each room on and off individually! How’s that for flexibility?
Power for All Your Entertainment NeedsThe massive power supply includes a multiple-secondary toroidal transformer rated at 600 VA and 100,000 µF of custom-designed capacitors mounted in copper-plated, anti-vibration brackets. Critical circuit components from WIMA and other world-class suppliers were chosen only after extensive auditory evaluation. The LAPT Hyper Power devices are the same as used in the Reference Series’ acclaimed PM-11S1. Current feedback topology insures astounding accuracy and control even under high-drive conditions.
Smart Technology for Superior SoundPhysically, the MM8003’s output stages mount on an extruded aluminum "thermal tunnel" for efficient heat dissipation. With four channels on each side of the tunnel and temperature-sensing forced air cooling, this configuration assures long-term dependability.
Features a "soft turn-on" circuit that prevents excessive inrush current
Balanced inputs for each channel adhere to the Audio Engineering Society’s "pin 2 = hot" standard. Single-ended RCA inputs complement the balanced XLR connections. And you can choose either balanced or single ended inputs for each channel individually for easy connectivity. Audiophile grade, gold-plated speaker outputs insure tight connections to your choice of speaker wire.
The MM8003 features a "soft turn-on" circuit that prevents excessive inrush current from tripping an AC breaker or fuse. In addition, you’ll find both input and output jacks for DC "trigger" pulses as well as RC5 jacks for total remote control convenience.
The chassis itself is heavy gauge copper-plated steel for maximum isolation from external vibration as well as electromagnetic and radio frequency interference. And chassis depth is only 16" so the MM8003 will fit quite nicely in a conventional system rack.
Elegantly DesignedThe subtly three-dimensional front panel adds the classic Marantz design touch. The physical attributes of extruded aluminum and glass-reinforced resin combine ideally for a shaped look and that integrates with any décor. Power. Functionality. Dependability. And classic looks. The MM8003 is Marantz through and through.
Please forgive some of the finger print smudges that jump out w/ flash. The condition is immaculate.
