Our take on the Marantz PM8004

Marantz based the PM8004 on design elements found in their high-end Reference Series separates. You don't get the fancy champagne gold finish, but you do get an amplifier section optimized for high instantaneous peak current capability. Put on a favorite CD or record album, and you'll feel like you're almost close enough to reach out and touch the artist.

Marantz based the PM8004 on design elements found in their high-end Reference Series separates. You don't get the fancy champagne gold finish, but you do get an amplifier section optimized for high instantaneous peak current capability. Put on a favorite CD or record album, and you'll feel like you're almost close enough to reach out and touch the artist.

With 70 high-current watts per channel, the PM8004 can plant a bass drum kick right smack in your solar plexus. Its shielded toroidal transformer does such a great job of minimizing noise, you'll savor delicious nuances in quiet sounds, too.

Plenty of inputs and outputs

The PM8004 gives you six analog audio inputs, including a high-grade MM phono input for your turntable. Separate preamp input/line-level output jacks allow you to use the PM8004 as an independent power amplifier or pre-amp for future system expansion.

Two sets of speaker outputs let you conveniently bi-wire a compatible pair of main speakers, or power a second pair of speakers in another room. The Source Direct mode bypasses the balance and tone control circuits to ensure the purest sound possible.

Praise for the Marantz PM8004 from The Absolute Sound

"With 70Wpc, the PM8004 is tonally neutral, clean, clear, transparent, and dynamic into low-efficiency speakers. The preamp section features an excellent moving-magnet phonostage and headphone amplifier, and the circuit has an unusually high number of discrete parts (rather than ICs). High value."

Great with CDs, Meh with Vinyl

Luke from Tuscaloosa, AL on 12/4/2013

Crutchfield Customer Review (What's this?)

I listen primarily to vinyl and some CDs via two-channel stereo. I purchased the PM 8004 to accompany a Rega RP-3 turntable with Elys-2 cartridge, Emotiva ERC-2 CD player, PSB Image T6 speakers, and--for receiver/AV use only--a Harman Kardon HK 3480 receiver. (Note that the Marantz is intended to replace the HK for vinyl and CDs). My listening room is approximately 25'x15', with hardwood floors, a vaulted ceiling, two tall windows, and no floor coverings (what you might call a little 'bright'). I enjoy all kinds of music--folk, country, jazz, blues, rock. The PM 8004 reveals previously unheard detail in my CD collection--it seems to grip my PSB speakers, making far better use of their considerable range than my HK ever did. In fact, I purchased my first CD in years to celebrate: Traffic's 'John Barleycorn Must Die,' which showed a richness that surprised seemed as if this heavily compressed music was, for want of better term, de-compressed for the first time. But with my vinyl, I am just a little underwhelmed. Here, the neutral tonality that so many of the other reviewers mention comes into play. Like so many vinyl lovers, I enjoy the warmth this medium provides, but the Marantz tamps this warmth down, pares it back. The Allman Brothers' 'Jessica,' from 'Brothers and Sisters,' sounds a touch too clean and untextured for my taste. I have not yet hooked up my Bellari VP-130 tube phone preamp to the Marantz, but I probably should!

Pros: Ability to wring the musical juice out of CDs

Cons: Some lack of warmth with vinyl

Fabulous Sound

JD from Louisiana on 11/29/2013

Crutchfield Customer Review (What's this?)

I purchased the PM8004 after previewing it's little brother, the PM6004. I was so impressed with the smaller version that I decided to go with the 8004. This amp has very impressive sound and range. Inputs include a Project Expression III turntable with a Sumiko Blue Point Evo III cartridge and Project Tube Box; a TEAC A3340S tape deck; aTEAC 3300SX tape deck; and a Denon CD player. Played through a pair of Quad L22 towers, the sound is fabulous. For the price, it can't be beat! Also, great service my Crutchfield advisor, thanks Kramer!

Pros: Accommodates two tape decks.

Cons: No tape monitor loop.

Exceeds Expectations

RobR from Austin, TX on 11/26/2013

Crutchfield Customer Review (What's this?)

I wanted to upgrade my amp from the NAD c326BEE and decided on the Marantz after doing research on this item. It certainly has lived up to it's reputation. I have it paired with the Marantz SA8004 SACD and it delivers a very good soundstage and dynamics. My speakers are Canton GLE490.2 and the Marantz has made them sing. These speakers require quality power to sound their best and the PM8004 delivers. Overall, I am very happy with this item as it is well built and provides quality sound no matter if you listen to Classical, Jazz, Rock or any other musical genre.

Pros: Solid build Involving soundstage and dynamics Superb speaker terminals

Cons: Wish the volume control knob had an indicator light to easily see the volume position

Not for me

Doug from CNY on 11/25/2013

Crutchfield Customer Review (What's this?)

I bought his Marantz because I have their 5000 series CD player and love the clarity it gives my old and remastered CD's. I am replacing a 25 plus year old TEAC with 110 watts per channel and 30 per channel on the surround side. . The build and design is awesome of the MARANTZ no question there. Very easy to hook up and understand. Running a pair of BOSE 301's, a MTX 8" sub and BSR EQ. Yes I know the 8004 is a step up. I have always been able to adjust the MTX and EQ to make the BOSE sound wonderful to me. After hooking up the 8004 the sound was as pure and clean as I have ever heard, and in Pure Direct mode it is simple awesome. Here is my one catch with the 8004, when really cranking it up and pushing the sound at high levels it would mute and turn the volume down on its own, when hitting a heavy note with no warning. Now when I listen to music it is very fluid up down and up again cranking the tunes. I simply did not understand the lack of push the 8004 lacked and all levels. Long story short and calls to Crutchfield and Marantz, Crutchfield said it had overload protection and the Marantz rep said he never heard of the problem I described. I sent the unit back with a complete refund. I would recommend this 8004 for possibly a different style of listener. I have since replaced it with a Yamaha 1020 and for me it is simply awesome it gives me a great amount of options to adjust and be fluid with my music and it will crank without any loss of clarity The Yamaha is designed for future use.

Pros: Very clean and pristine power.

Cons: Appears to lack punch and ability to be fluid with music volume. If you set the volume and walk away then maybe its for you. Marantz advertises their wattage as being more than the number, I disagree, My TEAC has more dynamic volume but not as clean. The Yamaha has it all the Bass lines actually vibrate like a bass string through overstuffed furniture, not the boom and gone. It is truly a better fit for me.

Loving my Marantz PM8004

fwhazelton from Midwest City Oklahoma on 11/16/2013

Crutchfield Customer Review (What's this?)

This Marantz integrated amp is everything I expected it to be, quality built with all the clean power I will ever need. I have my amp providing juice to a set of Polk Audio TSi 100 speakers and the sound is distortion free at any volume level. I have always wanted a Marantz amp and after my research I chose this PM8004 and I am very pleased with my purchase. Thanks to the folks at Crutchfield, my purchase arrived professionally packaged and damage free.

Pros: Outstanding performance, solid built with great looks

Cons: none

Marantz PM8004 Review

Tim from Manheim, PA on 10/10/2013

Crutchfield Customer Review (What's this?)

I have been very satisfied with the Marantz PM8004 Integrated Amplifier. The pleasing musical sound quality is very dynamic, detailed, and neutral. My bi-wired Polk RT1000P floor-standing speakers have come alive with this amplifier upgrade. Would highly recommend for a moderately priced 2-channel stereo configuration.

Pros: Sound quality. Built like a tank (27 pounds). Configuration flexibility with Tri Tone Controls, source direct mode, power amp direct in, bi-wire/bi-amp/speaker A/B connections, and pre-out/subwoofer connections.

Cons: None.

Marantz PM8004 Integrated Amplifier

Ken Z from Chippewa Lake, OH on 9/4/2013

Crutchfield Customer Review (What's this?)

I love this amp! I did my homework, shopped around and decided on this beauty. Thank you Crutchfield for all the technical support, great pricing and super fast shipping that you provided.

Pros: Excellent full-range soundstage... Full featured.. Super all around performance.. Gorgeous, well designed chassis and controls...

Cons: No

This was my first integrated amp..

SH from NC on 8/28/2013

Crutchfield Customer Review (What's this?)

I've always owned receivers, a Pioneer in the 70's and Sony in the 90's. I still have both but found it time to upgrade my system. I really like this Marantz integrated amplifier. I can't get over the clarity from what I was used to. The bottom line is this thing is very clear clean sound. It is pretty basic as far as features and I appreciate that, the focus seems to be music and the sound produced. It even pushes a pair of 100.00 speakers (set as my B) in my kitchen making them sound like expensive monitors. It took some time to acclimate, and at first I missed the depth or lack of punch I was used to from my receivers. If I were to improve anything it would be the addition of a loudness/bass enhancement button. I find myself leaving the bass set to 3 o'clock. It isn't a show stopper and the addition of a powered sub may take of it. I couldn't go back and would not trade this clarity for anything.

Pros: Good clean sound, a well designed product.

Cons: The choice of more bass produced directly from the amp settings.

Marantz PM8004

Walter B from Sun City, AZ on 8/11/2013

Crutchfield Customer Review (What's this?)

Was sitting on the fence for a while on this one, have an old vintage Pioneer SX 980 (1979) an it serves me well, but wanted to hear my old CD's some better, using a Onkyo C-7030 cd player with it. Made the move to the Marantz PM8004 an the matching Marantz SA8004! I know now this is a huge step up, its all I was hoping for an then some, using the SA8004 CD player an the PM8004 my CD sound like you are there fromt row center. I tunes sound about a half notch down from my CD collection but very very good, I feed the SA8004 with the tuner part of the SX980 and it sounds better than the SX980 feeding speakers by itself on a station that is 100 car miles away from my house, I do use an outside FM antenna with the SX980 which feeds the Marantz PM8004 for GREAT sound. I get what you pay for. Very

Pros: Marantz system runs cool, good remote, looks nice an is made well. But its really about how it SOUNDS for me!

Cons: Would like all features on remote, not just the important ones...

Excellent Integrated Amplifier!

GerryA from Jacksonville, FL on 8/6/2013

This little integrated amp is good enough to impress even professional audiophiles. If you haven't already done so, Google "PM8004 TAS 220" and follow the link to Paul Seydor's review of the PM8004, written for an audio magazine. In my opinion, his assessment of its sound is right on the money. I recently bought a PM8004 to replace some old Adcom separates (GFA535 MKII amp and GTP500 MKII preamp). The Marantz is better in every way; it's tonally neutral, clean, clear, transparent, and surprisingly dynamic. Based on some of the reviews I had read, I was expecting that it might be a little lean (bass shy) sounding, but that's not the case at all. The sound is full and accurate, and not lacking one bit in the low frequencies. The bass is well-defined, clean and tight, as opposed to loose and overblown, so if you prefer the later, this may not be the best amp for you. I will say, though, that I am a certified bass lover, and I'm extremely happy with this amp. You could pair the PM8004 with much more expensive components and it wouldn't be out of place at all. Truly hi-fi sound at a mid-fi price! Kudos, Marantz!

Pros: Sound quality and refinement beyond what I expected for the price. Tone controls (including the mid-range control) are effective and useful for taming bad recordings. Speaker binding posts are sturdy and well-designed. You can select / deselect "Source Direct" from the remote control. The blue lighting on the front panel is a nice touch.

Cons: It's difficult to see the settings of the tone control knobs. Power receptacle on back of unit is only two-prong. Not sure if aftermarket power cords can be used with this amp.

Just OK

Majog from NY on 7/9/2013

Crutchfield Customer Review (What's this?)

I bought this to replace a 25 year old JVC reciever which lost the right channel. I bought it with the understanding it had a tape loop and could drive my EQ and DBXIII. Unfortunately while it has a tape out it is not a loop and could not. The Crutchfield support team did a great job making it right and suggested a NAD integrated amp which I bought. There was no comparison between the 2 as the NAD was clearer, louder, crisper, and just all around better sounding for significantly less money.

Pros: Technical spec's; easy to set up

Cons: Sound quality; no preamp or tape loop.

Marantz PM8004

Anonymous from Middletown, CT on 6/15/2013

Crutchfield Customer Review (What's this?)

Bought new December 2012 from Crutchfield. Sounded great until I lost the left channel in June 2013. I shut the amp off and the next time I went to use it the left channel was silent. I will soon find out how good the warranty is.

Pros: Decent sound for the price.

Cons: Did not work for long.

Marantz PM8004 Integrated Amplifier

Dr. Russell from Dunbar, WV on 5/9/2013

Crutchfield Customer Review (What's this?)

I am pleased with the Marantz amplifier. The sound quality is excellent, and to me that is the most important criterion. I also like the layout of the controls and the remote, It is very easy to use. Switching from one input source to another is very easy to do.


Cons: It would have nice to have another two input source connections.

Super Integrated

Corelli from Grand Rapids, MI on 12/25/2012

Crutchfield Customer Review (What's this?)

This amp took me by surprise. While I expected good performance I was somewhat blown away at how well it drove a pair of current hungry Magnepan 1.7's. An unexpected pairing to say the least. Very smooth and musical but not without detail. Outperforms similar priced integrateds with more impressive specs. You can't always believe the numbers! A beguiling integrated that is a default recommendation at this price....or even higher.

Pros: Musical!

Cons: Nothing worth mentioning

A Nice One-Box Solution

Jason from Denver on 8/24/2012

Crutchfield Customer Review (What's this?)

I bought the unit to integrate into my living room setup which currently has a Denon AVR receiver. I use the Source Direct to allow the AVr to still handle the HT needs and then turn this unit on for the two channel stereo listening. After upgrading my front speakers, the Denon just was not enough to bring out their best and I wanted a dedicated two channel amp for music. My speakers are the Ascend Sierra towers with the RAAL tweeters. They are fantastic and they shine with the PM8004 driving them. The highs are bright, but not harsh. The midrange is well-defined and possibly a little warm, which I love. Bass definition is precise. I was surprised to hear the character of the bass notes seem so much more organic on jazz and classical recordings although I cannot Setup was easy. The binding posts are incredibly robust and show the level of quality that is inherent in this unit. Unless you want to spend twice the price, I really don't think you can get a comparable level of performance from anything else out there. Sound quality is fantastic with good, clean power. Be warned, however, that this unit will highlight poor quality recordings. I was surprised to hear a distinct difference from one disc to the next. Poor quality recordings need a little tweaking on the DAC and the tone controls on this unit to hide their imperfections. It will definitely steer you towards higher quality source material. All in all, this is a great option for someone who wante

Pros: Sound Quality HT Bypass Tone Controls Value

Cons: None.

precision, details and power!

Tony from Texas on 7/21/2012

Crutchfield Customer Review (What's this?)

OK so here it is: I started with the NAD M3 amp, and a pair of DEF TEC BP8040ST speakers . The M3 is a very powerful piece and it did sound good. However, for the price I expected more. It just didn't seem clear enough or have the impact I expected. So I called Crutchfields for a return. They are so awesome with returns no questions asked. I also returned the BP 8040ST's too. Next I auditioned the Harman Kardon HK990 with a pair of TSI300 Polk Towers (1/4 the price of the BP8040 ST's) and the PSW 125 Polk sub. I liked the HK990 better than the M3 because the mid frequency bass and musical details sounded a bit better but the high frequency realm seemed a bit muted. So as you can guess, I made the call and Crutchfields took this set back. Next I tried the Marantz PM8004 with the Polk speaker system, no change there. My ears REJOICED! The mid frequency was very tight and precise! The high frequency response was sensational. I listened to my "most played " in my Itunes and I heard all the details. My first listening session lasted five hours straight! I was PARALIZED and could not leave my couch. The Polk speakers had zero listening fatigue too! They are a good match. Oh and did I mention the power output of the PM8004 is enough and then some to spare. I have a 25 X 25 living area that was full of sound. Go Marantz you will not be disappointed! (note: I am running a Cambridge Audio-high end-DAC from my PC with audio quest Golden Gate RCA cables to the PM8004)

Pros: Great price for such high quality and performance.

Cons: It may not be in stock when you try to buy it. So do not wait!

Blown Away

BlakeB from Greer, SC on 4/2/2012

Crutchfield Customer Review (What's this?)

I am absolutely stunned at what a difference upgrading to this amplifier has made to the sound of my cds. It's like I'm hearing some of them for the first time. This might be the best $1,000 I've ever spent on stereo equipment! I've got this powering some 10 year-old JBL floor-standing Studio Series speakers and they sound amazing. I could not be happier with this purchase. Thanks, Chuck, for steering me towards the Marantz brand.

Pros: Power, Tri-Tone controls, built like a tank, powerful bass response, exceptional clarity and detail

Cons: nothing

Best for your money

murl from east coast on 8/3/2011

Not quite the power pusher of the seventies or even the eightys... however it is about the best you can get at this price point. Japanese made = quality. just turn the bass up a bit to enrich the sound and you should be fine. Otherwise you need some sort of outboard processer like an eq or something along those lines to get more fullness or push. I listen to all types of music. Hope this helps...



Quality behind Modesty

kob from Princeton, nj on 4/4/2011

Unit is not for those who look for something to show off, but for music lowers. Good enough replacement for my old amp, though sound is a bit "drier".



Marantz PM8004 review

Charles from Toms River, NJ on 2/20/2011

Crutchfield Customer Review (What's this?)

The first thing that pops out at you is how stylish and well built the 8004 is. The feel and look just scream quality and class. It is not just another "black box" stereo. This amp has personality and looks. Marantz seems to be getting back to it's roots of making good looking gear like their big 70's receivers. Even going back to using, and fun to use, tritone controls. The treble is very nice very smooth airy and easy to listen to. The midrange and upper bass is were this beast seems to come alive. A tremendous amount of detail and force in the midrange. This amp had dynamics and clarity in spades!!!!! The bass is very lush and full. This amp has NO problem in the bass department when using either a powered sub or good old fashion passive three way speakers with a 10" woofer. The bass is strong, dynamic and Very well controlled. Not boomy or slow. Very articulate bass and well balanced. The overall sound I would say about this amp is it is very full sounding, lush and VERY dynamic. Reminiscent of the sound of the big 70's receivers. But with far more clarity and imaging. NO listening fatique here. This amp is made for listening. I use my Marantz 8004 for almost entirely classical low level listening. So detail and articulate sound at low levels are my main needs. The 8004 carries it off without missing a beat. At low levels this amp maintains it's great dynamic sound.



Lots of Power, Retro Cool

Frank from Manhattan, KS on 2/16/2011

Crutchfield Customer Review (What's this?)

I use this amp to power my whole house speaker system- 11 speaker pairs. I wanted an amp that looked great, too, because it is on display in my living room. There are many choices for great retro looking, high performance IAs but their price is $ 2K and higher-too much for basically background music playback. The PM8004 was a great choice. Plenty of power, handsome styling, subtle blue LED lighting for active input-looks cool. It is also rather compact, but still hefty and very solidly built. The mid range tone adjustment is a plus-it seems to help today's digital sources sound a little better. I am very pleased with this amp.



Great amplifier

Miguel from Fort Lauderdale, FL on 2/13/2011

Crutchfield Customer Review (What's this?)

There is nothing to talk about this amp, "but a lot to listening". It is just great, as every Marantz product.



Classic Marantz Sound & Performance!

Cary from Merrick, NY on 1/6/2011

Crutchfield Customer Review (What's this?)

After months of research, reading many reviews and making detailed comparisons, I decided on the Marantz PM8004 and bought it from Crutchfield. And it has exceeded my expectations! For the price, this unit delivers detailed smooth sound, plenty of clean quiet power, great looks and features that other manufacturers leave out, such as a phono stage, connections for 2 pairs of speakers and triple tone controls. And it's built like a tank! In summary, if you're looking for true "high-end" sound, sophisticated engineering and design, practical features, value and quality build, it's hard to beat this integrated amplifier!

Product Research

Overview: The Marantz PM8004 is a two-channel integrated amplifier rated at 70 watts x 2 into 8-ohms and 100 watts x 2 into 4-ohms. In both the pre-amp and power amp sections, the PM8004 uses fully-discrete, high speed current feedback circuits for minimal phase shift and better detail resolution. Even the phono input is a fully discrete, constant-current design optimized for moving magnet phono cartridges. Marantz's HDAM SA3 (Hyper Dynamic Amplifier Module) performs critical stage-to-stage signal transfers. Five of the inputs (all but CD) share a buffer circuit to minimize unwanted interactions between the source and amp. The CD input has a separate buffer for even better isolation. The record outs are also buffered for enhanced recording clarity.



Chassis Construction: The amplifier's chassis uses a triple-layer bottom plate to insure long-term alignment and vibration control. The unit's front panel uses a combination of aluminum and glass-reinforced resin to create a distinctive three dimensional appearance. Indirect reflecting blue LEDs indicate the input selection.

HDAM (High Definition Amplifier Module): Marantz uses HDAMs instead of standard op-amps, resulting in a more dynamic sound with less susceptibility to radiated noise, heat, and vibration. The V/I converter circuit, the key block of the current-feedback pre-amplifier and power amplifier, is equivalent to the HDAM-SA3 amp-module developed for higher-grade Marantz components.

Momentary-Current Supply: The PM8004's main amp has the capability to momentarily pass 25 amps or more, providing high-powered drive to the speakers.

Short Power Line: To improve the momentary-current supply, the large current line connections are as short as possible, while remaining symmetrical. The individual power supply segments are located on the same heat sinks as the output transistors for quicker response to musical transients.

Discrete Current-Feedback Phono Equalizer: The PM8004 provides an all-discrete, current-feedback phono equalizer optimized for moving magnet (MM) cartridges.

Double-Shielded Toroidal Transformer: This unit is equipped with a toroidal power transformer to minimize vibration and leakage flux, which affects sound quality. The outside is double-shielded, using a core ring and a short ring.

Power Amp Direct: The PM8004 can be used as just an amplifier, with a separate pre-amp. Connecting the outboard pre-amp's output to the Power Amp Direct In input bypasses the PM8004's input selector, balance, tone, and volume controls. In this configuration the amp's signal to noise ratio is 125 dB.

Auto Standby: With the Auto Standby Mode turned on this unit will enter standby mode after approximately 30 minutes (continuous) of no output from the speakers or headphones.


Master Power: A mechanical switch turns the main power on/off. When off, the remote has no effect. When on, the remote can be used to switch between on and standby.

Input Selector: A rotary knob on the front panel is used to select the input source (Phono, CD, Tuner, AUX/DVD, Recorder 1, Recorder 2,). Using the remote you can select the input directly.

Bass: A rotary knob adjusts the bass output, +/-10 dB at 50 Hz.

Midrange: A rotary knob adjusts the midrange output, +/-6 dB at 900 Hz.

Treble: A rotary knob to adjust the treble output, +/-10 dB at 15 kHz.

Balance: A rotary knob adjusts the left/right balance.

Speakers: Two buttons allow you to independently select speakers A and B. When using headphones turn them both off; they are not automatically muted.

Power Amp Direct: To engage the Power Amp Direct feature hold this button for three seconds. This bypasses the PM8004's input selector, balance, tone, and volume controls.

Source Direct: When source direct is engaged the bass, midrange, treble, and balance circuits are bypassed.

Remote Control: The supplied wireless remote will control the PM8004 and Marantz CD players, DVD players, tuners, and tape decks.


Speakers: The speaker system A and system B outputs are binding posts. They are not 5-way posts, but will accept single banana plugs, pin connectors, and bare wire up to 10 gauge.

Line Inputs: The CD, Tuner, and Aux/DVD inputs have stereo RCA connectors.

Recorder: Recorder 1 and Recorder 2 each have stereo RCA inputs and outputs.

Phono: The stereo RCA phono input will accept moving magnet cartridges. There is a ground terminal beside the phono input.

Pre Out: Stereo RCA outputs feed a powered subwoofer or another amplifier.

Power Amp Direct In: Stereo RCA inputs feed the amplifier section directly from an outboard pre-amp when using the Power Amp Direct feature.

Remote control: An RCA Remote Control input and output are used with other compatible Marantz components; CD player, DVD player, Tuner, etc. This allows the included remote to control the other Marantz components.

Headphone: A standard 1/4" headphone jack is on the front panel. The speaker outputs are not automatically muted when you plug in headphones so the speakers must be manually turned off.
