Crutchfield Customer Review (What's this?)
Very pleased with the overall performance of the mm7025 power amp
Connect this 2 x 140-watt beast to the preamp outputs of a receiver or a wireless music player such as the the Sonos ZP90. Add a pair of speakers that can handle the high power, and get ready for a breathtaking sonic thrill ride.
Use the MM7025 in your main listening room to drive your primary speakers. Expect to hear tighter, weightier bass, and wider dynamic swings that bring you closer to the sound of live music. (If your speakers can be biamped, this Marantz makes a superb choice for driving the low-frequency half of your system.)
Audiophiles using a preamp or A/V processor with XLR outputs can connect to this amp's XLR inputs and take advantage of the superior sound quality they provide. You could also use this amp to power a second zone. If you're using a speaker selector to divide the second-zone power among multiple rooms, don't worry. There's plenty of juice here to go around.
The MM7025's current-feedback amplifier design provides for nuanced reproduction of fine musical detail and plenty of sonic muscle to support chest-thumping transient peaks. HDAM-SA3 circuits provide high-speed signal response for precise sound.
Very pleased with the overall performance of the mm7025 power amp

Very pleased with the overall performance of the mm7025 power amp
I purchasedthis amp to drive my Martin Logan, ESL X speakers through a pre-amp connection fron my Yamaha 781 AV receiver. Resulting volume is much better but sound quality is noticably better. The ESL X speakers arr power hogs so probably could have used a more powerful amp but for my home the Marantz 7025 is plenty good enough.
Pros: -Easy connection and configuration -dc power on/off compatable with Yamaha 781 - sound quality improvement over Yamaha 781 integrated amp
I purchased this power amplifier to run my B&W two front channels. I paired it with a marantz 6012 receiver for a 7.1.4 system. This unit runs my towers just perfect at 140 watts per channel and the sound quality is superb to my ears. It's got style, and performs great. I would highly recommend this power amp for any two channel needs.
Pros: Great power, style, performance.
Great sound. Had a scare when it didn't turn on, we must of had a power glitch as the front red light power indicator wasn't on. Cycled power to the unit and all is well. It must have gone into a protection mode.
Super easy to setup although I wish it just came with the rca plug though between the receiver either from Marantz or Crutchfield but otherwise it's awesome!
Pros: Great power to the two front channels
This Marantz amplifier is a monster! About a year back I picked up one of the slim model Marantz surround receivers (NR1606) that puts out a modest 50W/ch. Although I was pretty happy with the output to my 5.1 system, I couldn't stop thinking about those front channel preamp outs just sitting there, unused. I finally caved to the temptation to add some extra juice to the mix. I must say I was blown away and my expectations were exceeded as soon as I completed the calibration and popped in a blu-ray disc. My Rock and Metal collection has never sounded better, it's like a whole new system. I don't know how to describe it, but it's more than additional volume, it's like there's "horsepower to spare" no matter what volume I select. I can't say enough about this beast (except, well I don't think it's too smart, I hooked up a non-stereo monaural cable to the DC in/out from the receiver which powers up the amp at times, but mostly it just seems confused).
Pros: Conservatively rated power adds WAY more to your music or movies than just volume; it's quite impressive! Heavy, well built, high quality amplification.
Cons: Guess I'll have to mess with the DC jacks & settings a bit more to get this thing to power up/down with the rest of the system. Usually have to power up manually but it's worth the effort!
This Power Amp is the Truth, I have a Marantz SR5012 controlling this amp. Pushing a pair of Vintage JBL L100T as subs. Trust me, I Jamming. The SR5012 is pushing a pair of Bose 901's and a pair of Bose 301's with Polk S35 at center a pair of Polk S10's in the rear. In Multi Channel Stereo mode, every speaker is playing and it sounds good.
Great 2 channel amp to push my floor speakers. Most amps at this price and lower do not have the XLR cable option, which is by far a better way to connect your AV to the amp.
Pros: ease of connection to my receiver, I love the look and the style. Made me get the whole Marantz se up.
So I have a Marantz SR6011, sounded good and yes it does have the ability to bi-amp your front speakers on its own using its 110 watt per channel @ 8ohms with it's internal amp. Yes this is only 140 watt per channel @ 8ohms so not much difference, but having separate amps in my main room, I know how much of a difference a separate amp or amps can make. So initially I single wired my front speakers Polk Audio S60's using just the SR6011, with AQ Type 4 cables sounded ok, then tried Bi-Wiring Using AQ Rocket 33's, improved some but not dramatically, then I bi-amped 2 sets of Audioquest 4's , even better still with SR6011, talked to Polk and they said if you had a little more power they will open up more. So I added the MM7025 as pictured, and now have my fronts with (2) sets of full range Rocket 33's wired to the lows on my S60's using the MM7025, and Mid range and highs from SR6011 also full Range Rocket 33's, incredible how much better my fronts sound especially in 2 channel audio listening. Wasn't sure it was worth it, but in the end I am SO glad I did. Very happy, also a little odd that this runs so much cooler than my SR6011 (I use AC Infinity Aircom T8's) as pictured which monitors temps and cools off when necessary. This amp would probably be fine in a well ventilated setup with no fan, not the SR6011. (Also tried just the MM7025 and it did sound better than the SR6011) May actually buy another one down the road and run (2) MM 7025's to my fronts direct one per speaker
Pros: Runs cool, like 25 degrees cooler than my SR6011 with no external cooling fans (as pictured) after a few hours (with no external fans). Should be fine in any well ventilated setup without the need for extra cooling fans. Sounds better than my Marantz Receiver....higher peak loads than my Receiver. Can use Marantz Link to turn on with your Receiver. (Very handy)
Cons: Marantz does not allow you to bridge this amp unfortunately. Marantz does not offer a 3 channel version (would have been nice for my center) They do offer the MM7055 and MM8077, may actually pay the money get that and use the MM7025 elsewhere. I have Rotel Amps and I compared this to my RB-1572....this is about 60% as good but a little more than half the price :)
Bought this a year ago to go with the Marantz SR7010 in an 11 channel Doldy Atmos setup. The MM7025 is doing main front left and right duty and impresses to no end. Needless to say it meshes well to the Marantz A/V receiver in multichannel, but it is stunning when the old vinyl and CDs are pulled out for some plain old school stereo listening.
Pros: Impressive stereo performance, meshes well with comparable A/V receivers for 11 channel Atmos duties.
Excellent build quality and power to my Focal fronts, matches dimensions perfectly to the 6010 receiver! Strongly suggest! Might even pick up another in the future-
Pros: So far, everything!
Perfect powerful add-on to any system, but especially another Marantz receiver/amp (the built-in Marantz remote on/off function is a key, yes, auto sensing on/off 'works' but not as well in my opinion). And if you stack them, well, it just looks cool too. I have it driving my Left/Right Front Height speakers on an 11.2 setup.
Pros: Lots of power
Cons: Large and heavy
I really I really like this amp. It's preamp from a Marantz 1607 going to totem dream catchers. The sound is warm but clear. I a/b this with emotiva xpa. The latter was very bright and painful despite tone changes. This is a good piece of equipment.
Very happy with MM7025 purchase. Connected from Nad T748 pre out to Polk TSx440t Fronts, in 5.1 system for movies, and alone in Stereo for music. I had recently read a comment, in the Q&A section, on a website of a speaker manufacture. The customer was asking if his receiver was a good match for the speakers he was looking to buy, (note they were not talking about this equipment). The reply was that his receiver would, "Open them up nicely". The MM7025 did just that to my front speakers. Wish I had done this upgrade long ago.
Pros: More than enough power for my speakers, quiet, and looks nice with other equipment.
Marantz have always been a great name in the audio industry, This amp is no exception, for the price you are getting a bargain, good amps are always over 2,500 $ , I have paired it to a denon avr-x7200wa and that 11th channel comes to life with this amp,
Pros: Good price for the quality you get,
Cons: have not found one yet
I have only had this amp for a few days, it matches the rest of my new Marantz components perfectly, and I may never know the full extent of the massive power this bad boy puts out. But its good to have.
Pros: Its all good!
I use this with a vintage Marantz Model 3200 preamplifier to drive my series VI 901s. The 901s need a lot of drive and the 7025 does the job flawlessly, has the clean power and is rather transparent, also capable of producing a lot of clean bass with the 901s which is not easy. I have had the 7025 for 2 weeks now and would recommend it for this power and price range / fair sound quality.
Pros: Performs as expected, drives power hungry speakers well, looks great and seems to be well built
Cons: none so far
I'm driving this with the pre-out of a 1974 Marantz 2270, which I completely recapped in 2013. On the business end of the 7025 is a pair of Bose 901 Type II's. Other gear in the system is a Thorens TD125 MK II turntable, and a Revox A77 reel-to-reel tape deck. This amp is performing as expected by the other great reviews I read.
Pros: Easy set up, basically works right out of the box.
I purchased a pair of these for a project i am doing, but in the mean time i am using them to bi-amp a pair of Martin Logan SL3s. They have a great sound and are easily running the power hungry electrostats, though I am not pushing them hard as the speakers can drop impedence loads when pushed. The soundstage has been great paired with this amplifier. The only reason i give four stars is that one arrived D.O.A. One call to Crutchfield and the exchange process was underway. Excellent service. I had a return label within moments and shipped back the bad amp that very day. Very simple operation when triggered from my receiver. Auto shut off features work splendidly. So far so good.
Pros: Marantz sound, powerful and rich. Balanced and unbalanced inputs available for flexibility of connections. Matches my existing Marantz receiver with the porthole design.
Cons: Not stated as 2 ohm stable. Of 2 ordered one was doa.
I have been using this amp with a Marantz NR1602 receiver to drive my Bose 901 VI loudspeakers. It does this quite well. Previously, I used an Adcom GFA5500, which is a much heavier amp, rated 200W per channel into 8 Ohms and 350W / channel into 4 Ohms compared to the Marantz's 140/170 Watt ratings. Despite the power deficit, the Marantz sounds real nice with the 901's and seems to be stout enough for them. Admittedly, the 901's, even considering their EQ, are an easy load as they are fairly sensitive and present a uniformly comfortable impedance. The MM7025 is very quiet in operation. It has a cooling fan but I have yet to hear it come on. I hear no noise at all with this amp. Music, TV and movies just sound natural with the MM7025. It's pretty much a case of what goes in is what comes out. It seems to add no color or character of it's own. In my mind, that is exactly what an audio amplifier should do. The only thing that I've found so far to give Marantz a slight demerit for is the auto-off circuit. It works fine to automatically power down the amp after a pre-set inactive period, but it's not so good at turning it back on! I have to cycle the receiver's power off, then back on, to wake up the MM7025. No biggie, I just use my receivers sleep function. When it sleeps, so does the amp. Then when I turn the receiver on, the remote connection wakes the amp.
Pros: Beautiful looks! (If you appreciate such things!) Quiet operation Neutral sound Manageable size Fair price Good power
Cons: Not rated for 4 Ohm loads Auto power off circuit could be improved by including a signal-sensing function.
I got this to use for the left & right main channels of my Marantz SR7005 receiver. I'm very happy with the results. I think the MM7025 does a better job driving the B&W 604 speakers. The remote control connection to the reciever is nice. The amp starts up a few seconds after the receiver is turned on.
Pros: Nice sounding amp.
Using Arcam DAC into Marantz AV7005 to the MM7025, which is then driving B&W PM1s. Replaced a Yamaha receiver with about the same power. The difference is stunning, even the wife, who never listens was immediately captivated. Depth, clarity, power all great. No hard edges to the sound like some other amps I looked at. Really woke up the PM1s.
Pros: Depth, clarity big improvement. Looks match the AV7005 and are nice. Used banana plugs for out and XLR balanced connections for in, which worked great.
Cons: Nothing really.
Great sound for 2 channels. Has power and impact to spare. Once it was connected, not easy with only bare wires, worked like a champ! A high end value!
Pros: Great sound. Very nice looks.
Cons: Limited connectivity. Ruins wire with spade ends.
Excellent. Paired with a Peachtree Audio Nova Pre and pushing B&W 683s. Large presence at low volumes. HUGE presence as volume increases. Dead quiet to control chaos depending on the track. Using computer USB, Digital coaxial from CD player and Optical from an Apple Airport Express to stream. Would be the same combo again.

Current Feedback: The MM7025 is equipped with a current feedback circuit and uses the same complimentary push-pull circuit as the far more expensive SM-11S1 power amp, providing minimal phase shift and excellent detail resolution. The current/voltage conversion section has a Wilson current mirror circuit to improve circuit stability and high-speed processing.
Instant Power Supply: The final stage of the power amp uses the same LAPT (high efficiency power transistor) as the SM-11S1, offering instant power supply capability. The power section has a large transformer and Marantz original 15,000 μF / 71 V x 2 block condensers to provide a powerful, presence filled sound.
Heat Dissipation: The chimney-shaped heat sink efficiently processes the heat emitted from each side of the amp and a quiet cooling fan removes the heat from the chassis. A high-sensitivity temperature sensor IC is used to control the cooling fan's rotation speed to match the amount of heat generated by the amp.
Auto Standby: With the Auto Standby Mode is turned on this unit will enter standby mode after approximately 30 minutes (continuous) with no input signal.
Speaker Outputs: The speaker output terminals are binding posts; they are not 5-way posts, but will accept single banana plugs, pin connectors, and bare wire. A plastic collar prevents their use with spade lugs and they're too far apart for dual banana plugs.
Inputs: There are RCA (unbalanced) and XLR (balanced) inputs. Separate switches for the left and right channels specify which is engaged; useful if you're not using the MM7025 as a stereo amp.
Display: A blue indicator on the front panel display and a blue ring around the display light when the power is on; the blue ring around the display can be turned off if you prefer. Separate red indicators on the display light when the protection circuit or Auto Standby feature is engaged.
Remote Power Control: This unit is equipped with a remote power control function; when a compatible Marantz preamp is connected, this unit's power can be switched on and off simultaneously with the preamp. The RCA Remote Control input is connected to the preamp and the Remote Control output can be connected to other compatible Marantz components; CD player, DVD player, Tuner, etc.
Flasher Input: The IR flasher input is useful with universal remote controls; power and mute remote codes are available for the MM7025.
DC Control: The 3.5mm mini-jack input allows the MM7025's power to be controlled by another device (5-15 V). The DC Control output allows the MM7025 to control the power of another compatible device (12 V/44 mA).
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team. They verify what’s in the box, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.
I have read great reviews from others who have this product and how well designed it is and what it is capable of doing in a stereo system. This actually will be my first marantz product and I'm very excited about adding it to my system. Now I will buy the marantz 7012 receiver to complete my system. [ CASEY Oct 14, 2018 ]
Good compliment to my Marantz AV7703 for stereo listening. [ Scott May 15, 2018 ]
I have one of these already and just love it. I need it to power the rear speakers [ Lynn Apr 12, 2018 ]
To add a bit of muscle to my Marantz NR1606 AV receiver via the front channel pre-outs [ stickywicked447 Dec 29, 2017 ]
I asked the Tech to suggest a comparable Amp to bi-wire and run my front 2 floor speakers. [ John Nov 17, 2017 ]
Purchased the Marantz 6011 Receiver recently as well as new Polk Audio S60 Towers, The 6011 is nice but I want to see what some more power will do for the S60's so I plan to add this to run just for my Front Speakers the S60's, leaving the rest of the 6011's power for my other speakers and go to a 7.2.4 setup down the road. [ ANDREW Jul 27, 2017 ]
To drive sub bass [ KIYOHIRO May 12, 2017 ]
Required a little more power to front main towers in a 5.1 system. This fit the bill nicely. [ STEPHEN May 08, 2017 ]
Matches my system [ Rod Mar 23, 2017 ]
Needed a big amp to go with Marantz1506 I just received this amp will be a good match [ D Mar 04, 2017 ]
Wanted to add additional Marantz amplification for existing 9.2 receiver to upgrade to 11.2 [ mwbdcrown Aug 22, 2016 ]
Dexter recommended this as a good pair to my Denon AVR-X7200WA for the 2ch external powered amp needed for 11.1 surround. The power match-up seemed appropriate, and Marantz is another brand for quality. Dexter's Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=175 [ Charles Aug 16, 2016 ]

Feedback [ Peter Apr 06, 2016 ]
POWER!! [ Gary Dec 19, 2015 ]
You can as long as the speakers have a 12 ohm or higher impedence. If they are speakers with a lower impedence, then can only power one set. My Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=101 [ Paul Nov 30, 2017 ] Staff
I have used it with both 4ohm and 5ohm speakers...also depends on receiver, or pre-amp you are using it with. [ ANDREW Jul 29, 2018 ]
Since we haven't received any answers from other customers on your question at this time, I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. While it's true the Marantz MM7025 amp should work with 4-ohm speakers (under the right conditions), our Advisors can help determine whether this would be the right choice to work in your specific system. Thanks! [ Larry Aug 08, 2017 ] Staff
I think not. You would have to have some sort of output to connect to a preamp before linking to the power amp. I f there is an output option on the NA I would assume you could link to the power amp via an auxlliary input. [ TIMOTHY Aug 02, 2017 ]
Yes you it can send mono to each front tower speaker as long as the input device hooked up to the amp is sending mono to both speakers. Basically it is a pass-thru from input device to speaker so whatever signal is sent to the right speaker is what is amplified to the right speaker. Whatever signal is sent to the left speaker is what is amplified to the left speaker. The only change to the signals sent is that they are amplified, (made louder), so that the input device doesn't have to have its own amplifiers for each channel. Hope that this answers the question to your satisfaction, and helps. ;o) [ Charles Oct 13, 2016 ]
I'm not quite sure what you mean. If you want to only connect one speaker to the amp, vice two, then yes is the answer. An amp is a pretty dump device. It merely amplifies the sound, and maybe cleans up the sinewave of the output from your receiver or preamp device. I have a preamp and eight speakers (no center channel). I use the 7025 for my front left and right. Then another 7 channel amp for the other six surround speakers. [ Todd Oct 13, 2016 ]
Yes [ Nancy Oct 13, 2016 ]
Yes you can. I would check your speaker power maxium as you dont want to overpower them and risk damage. Your tuner/reciever will need to have enough pre out terminals to send signal to two amps. [ Lynn Oct 13, 2016 ]
I have components (DVD player, satellite radio and am old cassette tape player) hooked into an NAD pre-amp/tuner powered by the Marantz. Does your receiver have an integral amplifier? if so that may be a problem. If the receiver puts out an un-amplified signal I would think it would [ Patricia Aug 05, 2016 ]
This is a question for the experts at Crutchfield. As per the "about tech" Website, "...the R-S700 (includes a) multizone/multi-source feature, which allows a listener in Zone 2 to hear a different source than the main room. The receiver's non-powered Zone 2 output requires an amp and two speakers in the second zone. It comes with a separate Zone 2 remote control to operate the receiver from another room. Note: Multizone operation requires running speaker wires and IR (infrared remote) control wires from Zone 1 to Zone 2, which may require professional installation." The Marantz MM7025 will provide very good to excellent power amplification for zone two. Although it has a remote control connection via an RCA plug cable, the Yamaha uses IR. Given this, the remote operation may not work. Bill M. [ WILLIAM R Aug 04, 2016 ]
That all depends. Please follow the link above, and see if this will help answer your question. The MM7025 is a two channel amp. The Yamaha R-S700 appears to be a 2 or 4 channel receiver, depending on whether your speakers are 4, 6 or 8 ohms rated. I'm not quite sure that you will gain much with the addition of the MM7025, if all you are using only 2 channels. Best to check the web site at audioholics(dot)com for best practices. [ Todd Aug 03, 2016 ]
If your amp has main out and in yes.other factors are speakers. Over all very satisfied with my purchase very solid amp. Clear with good punch. Component compatibility will always be a factor. Your system for me can only be as good as your speakers [ Robert Aug 03, 2016 ]
To bi-amp with that Sony model, you will want to use the Sony to power the high frequency section of your Polks and then connect the Marantz to the zone 2 / "B" speaker outputs of the receiver, to drive the woofers. You will have to go into the set-up menu and select "A+B" speakers. Sony rates the receiver into 6 Ohm loads. All that means is you should be confident that it will drive speakers that are rated at 6 Ohms (or higher) safely. Only analog signals will be output from the "zone 2 / B speaker" output. That should not be an issue. [ JAMES May 05, 2015 ]
Hi Mark, Sorry but I can't help. I actually returned the receiver and never opened it. I was in the middle of painting and remodeling and figured it wasn't a good time to be messing around with this. Thanks, Pat [ PATRICK E May 04, 2015 ]
Yes, but you don't have to use it. It's purely optional. It also has a 12V trigger, which works great for me. [ JAMES Jul 04, 2014 ]
So frustrating it has no auto on feature... I have 5 airplay zones in my home and need and amps I can leave installed in a cabinet that turn on and off automatically when signal is sensed from an Airport Express. I have some older Sonance amps that do that now, but 2 have failed and I need to start replacing them with something better. [ shkalata Jul 04, 2014 ]
My system shuts down after 30 minutes (phone call with mother-in-law) and did not restart automatically. [ Pat Jul 04, 2014 ]
I have the mm7025 hooked up to a Marantz receiver there is a remote control cable as well as signal cables to the amp from the receiver. When I turn the receiver on the amp comes on .5 sec delay. the amp stays on as long as the receiver is on. It does go into standby mode when there is no audio signal present, but when in standby the ON blue light stays lit and the fan shuts down. The Amp is truly amazing as far as construction, twice the amp for the money compared to other brands.. [ GEOFFREY B Jul 03, 2014 ]
I have seen no evidence that it has an auto on feature. My answer would be no to your specific question. However, it does have the capability to install a "trigger", which detects that another device has been turned on. For instance, I have a series of amps, only have to turn on one, the rest are automatically triggered. [ VINCENT JAME Jul 03, 2014 ]
It depends on how hard you push the Klipsch now and how stout a 100W the Sony receiver is. Most A/V receivers, especially towards the lower end of the market, can't deliver anything like their rated power to all channels simultaneously. The Klipsch should be a relatively easy load, though, so unless you're really rockin', your Sony receiver should have enough power to drive them easily -for stereo music that is. If you like to crank up action flicks, putting an amp like the Marantz on the front channels will really lighten the load on your receiver. And even for stereo music listening, if you like the bass and like to listen at life-like levels, the bigger, beefier amp will definitely do a better job. [ JAMES Feb 06, 2014 ]
Appreciate the clear and interesting answer. Thank you for taking the time to reply and to educate me. [ Larry Sacks Jan 13, 2014 ]
Have never heard the fan. It does have one. [ NORMAN T Jan 11, 2014 ]
It does have a cooling fan. It's speed is matched to the amount of heat that is being generated. I have had this amp for over a year, use it almost daily and have never heard the fan run. This amp has a very low operating temperature. [ KEN Jan 11, 2014 ]
