Product Description
From the Manufacturer
From the Manufacturer
In-Wall Subwoofer Included
The 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 Needs
The 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 Sound
Physically, 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.
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 Designed
The 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
The Marantz MM8003 Power Amplifier – Multi-Channel Power Amplifier
As 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?

Over price and under power,

This review is from: Marantz MM8003 Power Amplifier (Electronics)
Pros:
Great appearance, clear and easy understand on the connections, 2 big 100K capacitors, copper plated chassis and all the screw, use high end design technology (just technology not actual components don't get confuse). Cons: 140W x 2 @8ohmz into 2 channels NOT 8 channel so in 7 channels driven at the same time don't expect true 140W RMS (It would sound like 80WPC when driven simultaneously all 7 channels). The front 2 side plates I swear it's plastic but according to Marantz the material is aluminum coated with crystal this may not bother for others but to me $2,400 amp make it feel & look cheap as this amp is a high end in Marantz line up. Unbalance preamp input are not gold plated only XLR balance input and speaker terminal are gold plated. Marantz proudly and sing about their massive toroidal power supply, but to me it considerablely small when compared it with my old retired Harman Kardon AVR 7300 RECIEVER that's right RECIVER not AMP which HK never consider their toroidal power suplly is massive. According to Marantz each channel deliver 140wpc RMS X 8 channels and this is suppose to be high current amplifier I would definitely drop 2 toroidal PS even though to some not all 8 will required the power at all time when in 7.1 movie mode, but in stereo the juice will be there ready when needed to deliver the true high current 140wpc to all hungry speakers. Sound: My old HK AVR7300 is now RIP so I decided to move on with an Onkyo 808 reciever as HK SURROUND technology is still far behind from other company. Onkyo 808 rated per channel 135wpc RMS, it does not seem to produce to spec so I went ahead and give Marantz MM8003 a try, why didn't I go with Onkyo 9 channels amp? because I lost confident on their TX-NR808 wpc rating. During Marantz amp test I really didn't hear any difference when playing in 6 channel stereo mode, as far as clear or louder comparing to my current Onkyo receiver tx-nr808 rating 135wpc which is only 5wpc different, bear in mind that I'm comparing high end Marantz pure amplifier to a mid entry receiver using a standard transformer. Marantz MM8003 amp seem under power in term of their claim 140WPC RMS, while comparing it to my old HK AVR 7300 reciever rated only 110 X 7 as the output to each speaker giving much stronger punch and clearer sound at much lower volume setting without distortion (HK is great for stereo music listener but horrible in surround decode processing) so if movie is your priority this is it but if you're a music lover look away. Conclusion: I'm not bashing Marantz products pretty sure their products are the best but this review conclude amplifier actually output, feel and see at giving test. At the end of the day I think the price set are way over for what the amp can produces and worth, if anyone going to drop $2,400 I would recommend to purchased a reciever and for the money ($2,400) which you most likely landed in higher mid or higher end receiver would do just similar job of this amp beside you will save on the preamp and get yourself a SACD player or BLU-RAY plus a few quality cables. ***update: I called Marantz tech support and were told that unbalance conection will have lower voltage rating than balance so with balance it will have higher gain. I don't have preamplifier to test this scenario out yet but will find out.

This review is from: Marantz MM8003 Power Amplifier (Electronics)
My last peace of equipment was the top of the line receiver from Yamaha. So I will compare it with that. I can't compare it with Krell, Mcintosh, etc. because I have never heard them. For me This was a great jump. Im using it in 5.1 with bi-amplification in front speakers. This option for me is the best. For movies I always use the 7.1 input of the preamplifier and for me this is a monster of unit. Delivers sounds in 3D. You can almost fell every person or sound in an specific room location. When used with music, I never knew my speakers sounded so great in Stereo Mode. Now I understand why hi-end users talk about 3D sound. And what a sound!!!.
