Customer Ratings & Reviews

First time buying an open box item at this price point. I was anxious about the condition of the unit as expected. I’m just glad it turned out great enough. The box was beat up and the styrofoam has 2 breaks at the top and bottom, assuming it took the hit when this package was dropped. Since the Marantz was well built, I was confident it didn’t affect it. Upon close inspection the unit had no blemishes or any signs of damage. It truly represented the “excellent” condition rating provided by Best Buy. The unit performs and functions perfectly, so far so good. I can’t give it a 5 until several weeks of use. If I can update later I will do so.

The statement on the box isn’t something they say with levity. Coming from a svs soundbase 300w class d amp with martin logan xtb100’s to this amp the difference was night and day between their dynamics. The marantz has such a better attention of detail. Songs like ciao papa from the new Pinocchio sounded astounding on the previously mention system but the exsquisite highs, attentive low end and carefully crafted midrange brought the track to such levels of beauty I honestly teared up a bit. Hdam 3 architecture is bar none, not to mention with the hifi class ab circuit its hard to find another amp that straddles this level of fidelity and musicality at a remotely similar value proposition. Also i was very impressed with the quality of the remote, good design, not metal but the in hand feel is very reminiscent of an apple tv remote with the weight and sturdiness.

Very nice unit. I have SR8015 for AVR but wanted a 2 channel streaming option. They brag about the phono stage but no amp I’ve heard has a great phono stage. The amp is beautifully designed. I run apple play off my iPhone , Apple TV, turntable, CD deck and KEF R3 Meta’s and my office rocks. Everything I need all works great and Marantz and the KEF’s are a perfect match. The 40n is warm and the KEFS bright oh SVS micro 3000 too. I haven’t done anything to the Marantz as far as set up because that HEOS app sucks. But I don’t care I don’t need it. I would like to see the Marantz menu though and apparently that’s the only way so I have some things to figure out. But out of the box this is a beautiful sounding amp.

Alright folks, I've been on a 6-month bender listening to Marantz' stereo amps since January. I first started with the PM7000, then the Model 30, and now the Model 40N. Take my thoughts with a grain of salt -- audio is always subjective and I'm a relatively new traveller on the Hi-Fi journey. I'll just cut right to the chase. The Model 40 is the absolute top end of what I would consider to be entry level Hi-Fi. What you're getting in one chassis is a quality integrated amp at 70w per channel, a reasonably good DAC, and a decent streamer. Let's break it down. Overall sound signature is very "Marantz." Warm, jammy sound that's rich and detailed. At first glance, it's probably everything you might want from an integrated amp. I did some side-by-side comparisons using my KEF R7 loudspeakers. First up was DAC capability. I used the integrated DAC with source from the built-in network streamer VS a Topping D90 with source from my TV via optical and Audioquest interconnects. Switching back and forth was mercifully easy thanks to Spotify Connect, and after a lot of listening, I can say confidently that the D90 does resolve more detail. HOWEVER... the fact that it took direct back and forth listening of the same few songs multiple times to really get a good impression of the 40N's shortcomings speaks volumes about what's in the Marantz. And there were actually things I preferred about the sound of the 40N, even though the D90 resolves more detail! Sound meshes more pleasantly using the integrated DAC, which is especially more prevalent in bass-rich songs. Ironically, "Gooey" by Glass Animals was the song that really made it click for me and spelled out what kind of sound the 40N is going for. As I said, warm, jammy, rich... "gooey." Moving on, the real question many people might have is how does it sound vs it's slightly beefier but less updated brother, the Model 30. That was the main question burning in my mind and with the 40N being so new, it's difficult to find comparisons online. I had the rare opportunity to do a side-by-side demo using my friend's KEF Reference 5 meta loudspeakers and, hoo boy, there's some differences. Testing equipment is as follows: Amazon Echo Link for source with optical out, Topping D90 DAC (we opted not to bother with the integrated DAC for consistency's sake), Audioquest interconnects to the power amp inputs on both amps. Direct 1:1 comparison. The first and foremost difference is straight up power delivery. The Model 30 just has more horses under the hood. Not a bad thing, they say it right in the brochure, but there it is. If you've got power-hungry speakers, the Model 30 is undoubtedly the better choice. I wonder at whether this difference is accentuated more dramatically by the Model 40N being an A/B amp whereas the 30 is a class D. Either way, the Model 30 delivers more volume. Detail is up next. The Model 30 offers texture, precision and urgency in it's delivery of sound. This is a HI-FI amp, meant to be listened to with a furrowed brow and stroking of one's chin. Imagine a buffet of resolved, detailed sound, sliced up with intention and put out on separate platters to be enjoyed individually. I wouldn't call it a cool sounding amp, but it's got a bit of a sharper edge than it's younger brother. That's the Model 30. The Model 40N is an amp made for the people. Sound jells together less intricately, but has a pleasant vibe to it. Songs are juicy, rhythmic, and musical. In a head to head against the Model 30, I prefer the more exotic pips and pops that the 30 can deliver. It sounds like something that even the layman would indentify as a high-end system. The 40N, with it's modern considerations and "everything but the speakers" mentality is, in my opinion, more value for the dollar. Honestly, a fantastic amp. You should buy it.

Very solid amplifier. I was able to hear the difference as soon as I attached my KEF R7's to it. The specs say 70W but the power is there. Easily comparable to the 200W Rotel amp it was supposed to replace. In the end unfortunately I returned it because I couldn't sync with the "Marantz" sound. Prefer more of a neutral amp. But really like it and I wish I could have kept it. The only con I would give it is the HELO app, its not user friendly and difficult to use.

Awesome Amp powerful and clean Worth every penny It can stream right off the internet bypassing Bluetooth if you wish to

If you have an opportunity to purchase the Marantz stereo system! Get it!! Hands down the best decision I've made in my music sound system! Has a premium look and feel and super heavy that feels high quality but the sound is out of this world! Sounds amazing either through Spotify or Vinyl Records! Would buy it again in a heartbeat!

Great amp with many options to support multiple inputs and components. Lots of power and sounds fantastic.

This amp is amazing. Out of the box it was a huge improvememt over my vintage mcintosh MA6100 which was getting serviced when i purchasd this. The clarity, detail, depth of sounstaging at this price range is truly remarkable. The phono section is second to none, i cant imagine any integrated phono stage sounding better than this one. The lack of a second speaker out is utterly displointing. The lack of native support for Qobuz also a drawback, but im using a UPNP app which streams all lossless sevices over DLNA to the marantz. Biggest issue is that after 3 weeks of use when i had the "tone direct" mode on, the right channel went out! With tone direct off, both spealers worked fine. Marantz detemrined this needed repair. I argued i should get a new unit, i dont want a refurb unit after less than a month of use! So i bought a new one on BB to swap out, the box was destroyed! So i refused that and ordered yet a thurd unit. At $3000, this is pretty inexcusable and i dontbcare what the return policy is, its a $3000 Stereo that broke in less than a month! An automatic replacement is the only suitable solution, not me having send in for repair. The next step up from this would be Luxman at double the price, we will see how long this one lasts, hopefully its the long term solution ive been looking for.

WASNT SURE IF I WANTED TO PULL THE TRIGGER ON A $2500 DOLLAR AMP BUT…..YOU GOTTA HEAR IT TO BELIEVE IT! SIMPLY PUT…..AMAZING! YOU WANT YOUR SYSTEM TO REACH NEXT LEVEL? THIS ONE WILL DO THAT!

The one to beat under 3k, this stereo integrated is warm and so easy to listen to for hours on end

Sound is superb. But networking is awful. And if you try to use the HDMI ARC input, forget about it. I routinely have to unplug the whole unit to have it play from my iPhone — and the app is awful. Expected way more at this price point. I end up using a $100 BT speaker most days. #fail

Bought the silver/gold amp elsewhere since BB is sold out. I have high end speakers and enjoy a film on my new LG OLED 4k EVO tv (bought in BB 08/22). The back of the amp has connection capabilities I find one of the best available on an amp for speakers, HDMI/arc, optical, coaxial, HDMI. Audio is clear, clean, sharp, just outstanding. HEOS is incl. Just download the amp to play your music from Spotify, SiriusXM, Pandora and more. Or pair your devices using Bluetooth. I'm still learning to use other functions of the amp.
