This 5-channel amplifier rated at 140 watt per channel into 8 ohms is capable of long-term power delivery into low impedance speakers. Equipped with an El-core transformer and LAPT (high efficiency power transistor) the unit boasts a massive power supply, which coupled with current feedback circuitry delivers powerful sound with astounding musical accuracy. All output stages feature identical topology for uniform high-quality sound across all channels, and the MM7055 lets you choose between balanced (XLR) and unbalanced (RCA) inputs for each channel, for maximum system configuration flexibility.

    • Very clean and fast...
I'm not so sure I want to buy the McIntosh 5 channel amp after living with this for a while. I'm driving a pair of Bowers and wilkins 706 S2 speakers bi-amped with this think. The sound is amazing. I was driving a pair of Klipsch RF82 towers for a while with it and the sound was again amazing. I starting to believe any speaker you feed with this is going to sound good. I haven't had any issues with mine and I never turn it off. The pre-amp is the Marants AV 7705 ... show more

    • Excellent Product
Excellent product, you cant go wrong with this. Would have been nice if it had a remote to turn on and off. Trigger is the only way to turn the AMP on and off using a remote, or manual control. When the receiver goes into sleep mode, it turns off the AmP. The AMP doesnt wake up when receiver comes out from sleep mode. ... show more

first off I'm a DJ I work with audio and video for over 20 years me and my family have always enjoyed Marantz products I grew up in the seventies my dad had a Marantz stereo in the mid-90s I bought an Marantz Sr 18 it sounded beautiful I even had the Marantz monoblock amplifiers Ma 700 now let's get started with my review it's probably going to be long the boxes that came in were inadequate for shipping there was a hole in one of the boxes and a scratch on the face plate that didn't bother me it's a very small scratch I bought two of these and I'm using all 10 channels after I got everything plugged in I thought this doesn't sound good I was using cheap XLR cable so I bought XLR cable which cost me almost $500 it's still did not sound as good as I thought it should then I bought 10 gauge speaker wire it's still didn't sound the way I thought it should at this point I'm thinking there must be something wrong with the electrical in my house so I bought a emotiva line conditioner and guess what it's still sounds cheap and distorted let me put it to you this way I have cheap Pyle Pro amplifiers that sound exactly the same as this Marantz amplifier I would like to return them but Amazon said it's over the 30-days I want to be clear I am not upset that I spent over $2,000 on these amplifiers I'm upset that I spent over $2,000 on amplifiers that sound like cheap garbage ... show more

    • Nice and Powerful, But For a Niche Market
Review Image by DL DL
First off, I'm a verified Amazon buyer, but this item has been relisted since. My experiences with this amp are very positive, and I could not be more satisfied. It is a powerful amp despite some limitations on paper to which I'll pay lip service later. And of equal if not greater importance is that it is a clean and powerful amp despite what some would say are limitations on paper. As far as build quality, it goes without saying that its build is quite proper. This is a Marantz after all. It feels solid and is solid all around. I've been using it for almost a year and occasionally at full throttle. It has not flinched or faltered in any way, shape, or form. Those tower speakers aren't the easiest to drive and this amp pushes them effortlessly, and with room to spare. At 10 feet away the room correction software set those channels to -2 & -2.5. So, if you're in a similar space this amp is plenty -- even moreso with speakers that need less power. Those are 2 dedicated 5x7 subwoofers in those towers and they pound with this amp. So, in this price range people want some things that this amp doesn't have as far as paper specs go. First it's an EI transformer as opposed to toroidal. Also, its noise specs along with damping factor and power with all channels driven seem a little flakey compared to its competitors. Also, it weighs barely over 30 lbs -- making it not much heavier than many A/V receivers. A lot of folks factor weight into an amp's potential, which is understandable in some respects. So, here's the thing: that's a big EI transformer. It's way bigger than the ones in AV receivers rated at 125 /chann anyway. I haven't personally inspected AVRs with 140 wpc ratings, but their EI transformers in the pics don't look as big as the one in this amp. It's huge. Its capacitors, which I guess are part of the whole power output formula, are also huge. 65,000uf in total. Compare that to the Marantz flagship receiver rated at 140 watts/chann, which has total capacitance of 44,000uf. When I peeked inside this amp, those two big R2D2 looking things jumped right out at me and assured me that all was well. Weight....it has less to do with the power output and more to do with the construction. Marantz decided to skip putting adequate heatsinks in there. Instead they utilized an aluminum "cooling tunnel" that snakes around the inside of the amp. A fan blows into the tunnel, spreading chill vibes all around. It seems to work. The amp stays a lot cooler than the AVR, and the AVR isn't even powering any channels, lol. I think it's actually the DSPs that are heating up the AVR. I dunno. But the amp weighs less than typical for its output due to the lack of heavy heatsink weight. Also, the lack of heatsinks is why this amp is not spec’d at 4 ohms. I think Marantz does say it can do 4 ohms, but I guess it isn’t recommended. S/N, thd, damping, etc....not bad by any stretch, but leaving something to be desired just looking at the specs alone. That's when "niche market" comes into play. What you're paying for with this amp are 1.) the renowned "Marantz sound," 2.) those fancy XLR inputs, and 3.) a lot more power than the vast majority of a/v receivers can offer. You’ll notice that a lot of circuitry and wiring went into to the proper set-up of the XLRs. If you don't plan on using them, then it just makes you wonder if $1,199 is the right price. And, yes, the "Marantz sound" is definitely there. In addition to the obvious power boost adding to the dynamic range and stage, the propriety HDAM circuity found in Marantz products imparts a very noticeable "warmth" onto everything--and I mean everything. The sonic characteristic of my home theater was completely transformed. ....transformed for better or worse is the age-old debate. Many audiophiles have a special place in their hearts for the Marantz "warmth." Others don't, believing it's a form of coloration if not just some marketing gimmick. Marantz claims that its proprietary HDAM circuity "buffers" noise. What I will say is that it does sound quite nice, and it does not --as far as I know-- introduce any distortion. Nuances are not only clear, but also more clear when compared to running things with the AVR alone. If you believeth in the HDAM, then I guess the logic is that the buffering adds realism, and that said realism is revealed through a softness of auditory texture. It's like playing vinyl through a tube amp but not really. Sony during the 1980s experimented with making their CD players sound like vinyl, but then abandoned the idea. That's another discussion. So, for $1,199, you get 1.) plenty of power output compared to even higher end A/V receiver internal amps 2.) the Marantz "warmth," and 3.) a seriously stylish amp that looks fantastic in the living room. Also....XLR inputs if you want 'em. ... show more
