Product & Company History

The CINEMA 40 is near the top of the new Marantz Cinema Series lineup. We will go over all of its features and hopefully help you decide if it is the right audio-video receiver for your home theater system.

The CINEMA 50, which is the model below the CINEMA 40, offers a whole lot of value for the money and we’ll also go over some comparisons between these two models.

Marantz Cinema 40

Design & Build Quality

The CINEMA 40 is a full-scale home theater receiver with 9 amplifier channels built in and a large array of inputs and outputs. It can easily be the heart of a great home theater system.

To try and uphold their tradition of making gear that sounds natural, Marantz has a program in Japan where they train engineers to be what they call a “Marantz Sound Master”. They will learn to identify the type of sound that has made Marantz famous and perform many listening tests as a product is being developed. While it is not clear if this is done for every single Marantz product, we know for a fact the new CINEMA 40 went through the Sound Master listening process to fine-tune its sonic signature for that warm Marantz sound. The CINEMA 40 is even made in the Shirakawa plant in Japan.

Build quality-wise, we have always been impressed with the way Marantz puts their units together. On both the CINEMA 40 and CINEMA 50, you get an aluminum front panel with the cool new look they launched with their Series 30. You can tell Marantz believes these are built to last as they put a full 5-year parts and labor warranty on both units.

Features & Technology

The CINEMA 40 has just about everything a home theater enthusiast would want in a top-end all-in-one receiver. On the video side, you get seven 8K inputs and three video outputs with zone two and three audio. These all support the latest HDMI 2.1 and HDCP 2.3 specs. The CINEMA 50 in comparison has six 8K inputs and zone 2 only.

A video input feature that may be important to those of you with older video sources that do not have HDMI is a single-component video input and 2 composite video inputs. The CINEMA 40 has what is called their A to H circuitry to upgrade those low-res video signals to a higher resolution too. The CINEMA 50 only has HDMI video inputs so you score another with the CINEMA 40.

The CINEMA 40 and 50 both have 5 analog inputs including a MM phono input and 2 each digital and coax inputs. No difference there between the two units.

When it comes to handling surround sound formats, the CINEMA 40 and CINEMA 50 have them all covered. Both have Dolby Atmos, DTS:X, and one that not many AVRs have these days, Auro 3D.

We were very curious if the CINEMA 40 had an upgraded DAC set over the CINEMA 50, but it turns out that both use a very expensive Analog Devices DSP chipset. So in terms of how the unit renders immersive audio effects, they will be the same, and they do an incredible job there. Both units have onboard processing for 11 channels plus 4 independent subwoofer channels. For those of you who know that multiple subwoofers are even greater than the sum of their parts, this is fantastic news! Being able to use the built-in Audyssey Multi EQ XT32 to adjust each sub individually is a huge deal! Also, all of the 11 channels have preamp outs so you can add a power amp to any channel set when you are ready for an upgrade.

While they come with Audyssey, there is an option coming that will allow you to upgrade either of these to Dirac Live room correction. The timing and pricing of this have been the subject of a lot of speculation but we finally have what we think are some solid dates and prices, but of course, these could all be subject to change. There are also rumors floating around about a new version of Dirac on the horizon. We are not sure if that is why Marantz decided to wait or if that will be an option on these. There will be a bandwidth-limited version of Dirac Live coming in the spring of 2023 which should sell for $259. This will be plenty for most people as where you really want to perform room correction is below 500 Hz, which is the cut-off for this version. The full-band version will be $349. Dirac also offers an option that, to our knowledge, is not included with any AVR or processor called Dirac Live Bass. This takes subwoofer blending to a new level and it looks like this will be priced the same for the Marantz units as other brands which is $349 for a single sub and $499 for multiple subs. However, this upgrade will not be out until sometime in 2024. If you do the Dirac upgrade, we highly recommend you purchase a good microphone like the one from MiniDSP as the old saying “garbage in garbage out” really applies here. In this area, there is no real difference between the two units.

Both units have all the major voice control and streaming through Heos and a great on-screen interface to help walk you through the setup. We do want to mention that if you purchase your Marantz Cinema series from Audio Advice, you are supporting our small business and you will get our great technical team of audio-video experts who are there to help our customers get the most from their home theater or audio systems. Plus we have free shipping and a price guarantee.

Both the CINEMA 40 and CINEMA 50 have 9 powered channels built into them which means all you need to do is add a 2-channel power amp to take either to an 11.4.4 system, which is very impressive.

Speaking of amplifiers, that is really where the big difference is between the CINEMA 40 and the CINEMA 50. The CINEMA 40 is rated at 125 watts per channel with 2 channels driven across the full audio band at .08% THD. The CINEMA 50 has a rating of 110 with the same specs. At first look, you may not think the two are that different, but when you look under the hood, you can clearly see the power amp sections in these units are not the same.

Marantz uses upgraded parts in the signal path of the CINEMA 40. And if you look closely, you can see that each of the 9 amp channels is on its own circuit board. The other obvious difference is the CINEMA 40 is taller than the CINEMA 50 by about 1 ½”. This is to support the much bigger power transformer you find in the CINEMA 40.

Performance Testing

Since we had already been really impressed with the sound of the CINEMA 50 in a full-blown home theater, we decided to test them in a stereo comparison to see what kinds of differences we would hear between what are clearly totally different amplifier sections.

We set up the CINEMA 40 and 50 in a system with B&W 703S3 tower speakers and used the Marantz SA-10 Reference CD player as the source. Both receivers were put in Direct mode. After we flipped back and forth, just once, it is clear the CINEMA 40 is warmer, more effortless, and just seems to control the deep bass much better. Don’t get us wrong, both were very pleasant to listen to with the classic Marantz warm sound, but the CINEMA 40 epitomizes the sound those Marantz Sound Masters use as a reference. Did it produce as wide and deep soundstage as some separate components that cost a lot more? No, nor did it have the ultimate inner detail you get with expensive separates. But what it does, is nothing wrong. It is extremely easy to listen to and could probably fool some of your audiophile friends into thinking they were hearing something other than a great home theater receiver.

Overall Recommendation

So, the big question comes down to is the CINEMA 40 worth the extra cost over the already great CINEMA 50? If you need legacy analog video inputs, must have 7 HDMI inputs, or must have 2 other zones, those will be the factors that lean to the CINEMA 40 . We feel like most people will not have those needs and it will purely come down to the audio performance. If you enjoy 2 channel stereo, to our ears, it is worth the extra cost. Or if you have speakers that are on the lower end of the sensitivity spectrum, the extra guts offered by the more robust power amp section will be another reason. However, if you are more about all of the great features, you’ll find them on the CINEMA 50 with its very good amp section, and it may be the better choice and will allow you to take the price difference between the two and put it towards better speakers or a second subwoofer.

We have two wonderful choices in the CINEMA 40 and CINEMA 50 with everything they offer and you really can not go wrong with either one. Of course, the home theater geek in us then needs to take a look at the Marantz 8015. It has dual versions of the same DAC’s, 2 more channels of processing for 13 plus 2 subs, more analog video inputs, and 7.1 analog in for those SACD fans. Plus it has a far beefier power amp section. But you will give up 4 independent subs as it only has two and there is no Dirac Live upgrade option which in our opinion gives the CINEMA 40 an edge.

We hope this review of the new Marantz CINEMA 40 home theater receiver has given you some good insight into the features you gain when you step up from the CINEMA 50 .

4 Independent Subwoofer Outputs

Immerse yourself in evenly distributed, accurate bass. Featuring up to four subwoofer outputs to smooth out low frequencies and provide better dispersion. No audible peaks or dips - just powerful, room-filling bass.

Two Subwoofer Modes (Standard vs. Directional)

Giving you even more freedom to tweak your subwoofer settings to your preference when you are connecting more than 2 subwoofers. Select "Standard" if you want evenly distributed bass performance equally throughout the room. Audyssey sub EQ HT will be engaged to provide a global filter to all subwoofers and will give you broader sweat spot in the room. Select "Directional" if you want more directional bass performance seamlessly integrated into each speaker channel closest to each subwoofer. Bass feels different depending on where you sit in the room.

Pre-Amplifier Mode

With Pre-Amplifier Mode, your receiver works as a perfect 11.4 channel AV preamplifier with the latest HDMI connectivity. Pre- Amplifier Mode provides a cleaner signal path and more tolerance in clipping level by disconnecting internal amplifiers. The receiver features 11.4 channel preouts. You can also disconnect only selected speaker channels so that you can use receiver's built-in amplification to drive non-critical channels, yet getting cleaner signal path for the channels driven by external amplification such as Front L+R. Enjoy the best of the both world.
