Do I need a 3D home theater sound?

And since I decided to review models with outstanding characteristics made to create a real home theater, we must understand the need to have a crucial element of the home theater. Namely, 3D or surround sound.

Movie engineers use 3D sound to enhance immersion and the viewer’s auditory perception. In simple terms, sound comes from several different directions around the user, using several specific audio channels or dedicated speakers. And as you already know, almost all Blu-ray movies have a volumetric sound.

That is why the receiver must support at least configuration 5.1 to create a sound stage with the listener in the center. Alternatively, there may be 5.2.4 or 7.2.2-system support for even more immersive surround sound. But the 9.2 home theater systems are not only optimized for surround sound, and manufacturers often try to equip them with extended video capabilities and various additional features. First off, I will talk about the testing methods of the selected models and then proceed directly to the review.

How I picked and tested 9.2 receivers

Since I analyzed the selected models not only on the sound and video side but also on the general functionality side, it would be good to talk about my setup for these tests.

I used the following equipment for the test and I evaluated volumetric sound using the example of the movie Deadpool 2:

• CD player SACD 30n
• Blu-ray player Sony UBP-X700
• Speaker wire – AudioQuest Type-9
• Speakers for movie – Klipsch RP-8060FA
• Stereo speakers:
  • Klipsch RP-8060FA
  • KEF Q350
  • DALI OBERON 5

I listened to the following tracks in different genres from different sources:

• Radiohead – The National Anthem – Spotify
• Bob Marley & The Wailers – Turn Your Lights Down Low – Deezer
• Arctic Monkeys – Do I Wanna Know – SoundCloud
• Led Zeppelin – Ramble On (CD player)
• The Weeknd – The Hills (CD player)
• Jacky Terrasson – Reach (CD player)
• Mark Nauseef – With Space in Mind (CD player)
• Mahler – Symphony No.2 (CD player)

I have a completely different configuration for evaluating surround sound. It comprises a Klipsch RP-8060FA set and a Sony UBP-X700 Blu-ray player. The speakers were connected to each receiver using an AudioQuest Type-9 cord, and I hope you already know how important a good connection is. So that was my kit, and now we’re getting to the fun part.

Denon AVR-X4700H – best overall

Denon gives a special role to the X4xxx line of receivers. This series belongs to the premium segment, as it is made on a more advanced component base, comes in an ergonomic design, and is packed with various features. But at the same time, such models are sold worldwide and in large quantities. The popularity of this series is explained by the fact that you can deploy a large home theater for all modern cinema formats and audiophile music system on its basis. So let’s take a quick look at what the new representative of this series has to offer.

The Denon AVR-X4700H with nine amplification channels and dual subwoofer outputs can drive 5.2.4 or 7.2.2 channel speakers or in stereo at 125W per channel at 8 Ohm or even 165W, and 200W at 6 Ohm (on one channel).

However, significant changes were made to the video block. The Denon AVR-X4700H is among the first receivers to adopt the HDMI 2.1 standard with support for 8K at 60Hz. All HDMIs accept Dolby Vision and HDR10 +. However, only the main output is 8K with eARC and HDCP 2.3.

And I draw your attention to the fact that here we are entering the top speed of digital video requiring short 48 Gbps cords, at the risk of obtaining no image. Moreover, the AVR-X4700H decodes most of the modern surround sound formats:Dolby Atmos, DTS: X, Auro-3D, and IMAX Enhanced. And this is one of the main (but not the last) trump cards of this model.

Separately, the calibration attracts my attention. The Audyssey MultEQ XT32 is present with its procedure going through eight measurement points. However, the novelty of the AVR-X4700H consists of offering two distinct memories that can be recalled from the menus. It is thus possible to create a curve for films and another for music. That is not found in any competing device, even, for example, in the Marantz SR7015.

The AVR-X4700H has a built-in phono stage, all network and streaming playback features are implemented, as well as the multi-zone benefits of wireless HEOS. As I said above, Audyssey MultEQ XT32 is responsible for multichannel calibration and the sound quality in pure musical mode – an advanced digital platform D.D.S.C. HD Digital (includes audio processing AL32 Processing Multichannel, contains jitter suppression circuit, DAC Asahi Kasei AK4458VN) and seriously modified power system, which has a powerful shielded transformer and more capacitor “buffer.” By the way, the latter is made on custom high-quality electrolytes with a polyolefin dielectric.

I started a test configuration with a subwoofer. When listening to music through the HEOS system and Tidal, I can say that the AVR-X4700H is doing with honors. In direct stereo without a subwoofer, I found my speakers’ sound signature, which received enough current to hold the membrane in the bass convincingly. The sound stage is wide and high, with good positioning of vocals and instruments, but lacks warmth and support in the low-midrange.

Now let’s move on to multichannel on my best 9.2 receiver tests. The film atmospheres are correctly transcribed, giving the impression of being at the heart of the action, surrounded by all the events. By default, the sound of Denon receivers is pretty focused on voices but is already well-supplied with dynamic bass.

Denon AVR-X3700H – under $1500

It’s time to introduce you to yet another receiver from Denon. The AVR-X3700H is a nine-channel device with 105W per channel power at 8 Ohm or 135W at 6 Ohm. In fact, you have a choice of configuration. However, the AVR-X3700H can handle 7.1.4 channels simultaneously. For this, outputs with pre-amplification are here, counting on the addition of an external stereo power supply.

I would like to point out that this Denon has the latest sound standards. It can decode Dolby Atmos and DTS: X as well as IMAX Enhanced. And another helpful feature is the presence of DTS Virtual: X technology and Dolby Height Virtualization Modes to simulate ceiling speakers.

The situation is also good with video capabilities. Here you can see 8K compatibility via HDMI 2.1 input and output. In addition, most standard video technologies are present here, such as HDR 10+, which the Denon AVC-X3600H did not have.

I was impressed by this 9.2 surround sound receiver`s sound. The AVC-X3700H recreates a feeling of an enjoyable and genuinely immersive sound environment. The excellent link is there between the fronts and other speakers with effects. There is at no time a cut between the two zones, which is one. Within this three-dimensional space, the sound objects move entirely freely.

In Deadpool 2, in battle scenes where sounds spring up from above or across the room in front of us, between the fronts and surrounds, the 3700 masters its subject and place the elements where they need to be.

Marantz SR6015

Next on my list is the Marantz SR-6015. This receiver uses high current-carrying discrete component amplifier circuits. Thus, it can deliver 220W per channel at 6 Ohm or 2 x 110 watts into 8 ohms in stereo, which is a perfect figure for a mid-budget 9.2 channel receiver. The SR-6015 has the latest immersive multi-channel audio decoders. It can broadcast Dolby Atmos and DTS: X audio streams.

The SR6015 did a magnificent job with my test system. The first listening without calibration gives a calm, even, very nice sound stage. Whether it’s multichannel listening or stereo music, the SR6015 doesn’t have aggressive highs or dominant lows.

After going through Audyssey MultEQ XT32 calibration, the changes were quite significant. In a positive sense, of course. Here, I was able to enjoy the volumetric sound in the film entirely. The subwoofer is perfectly synchronized with the rest of the unit and gives deep bass, explosions and other special effects that are “physically” felt. Everything was set up perfectly automatically, there was nothing to tweak. I also want to note that the receiver perfectly reproduces dialogues through the center speaker.

Budget 9.2 Receiver Reviews

Onkyo TX-RZ50 – budget

The first model on my list in this segment is the Onkyo TX-RZ50. Despite its budget price, this receiver is the flagship of the brand’s lineup. Still, most importantly, it can offer superior functionality, for example, support for 8K/60Hz video resolution and the ability to expand the system to an 11.2 configuration. And this is what makes it most advantageous compared to Denon AVR-X3600H and Onkyo TX-NR797, but also the most expensive in the budget category.

So, with the TX-RZ50, you can build a 7.2.4 home theater configuration for the most optimal Dolby Atmos, with 120 W/Ch power (8 ohms, 20 Hz-20 kHz, 0.08% THD, 2 ch). Of course, it is inferior in sound clarity to more expensive models at maximum volume, but the receiver sounds great if you do not turn the volume up to maximum. By the way, Onkyo has a very good range of speaker adaptability from 4 to 16 ohms.

You can simultaneously broadcast video and audio in a Multi-room system (2 Zones for video and 3 Zones for audio). You can also use wireless streaming with several options, including Sonos (but you’ll need to buy a dedicated port separately), Chromecast built-in, AirPlay 2 and DTS Play-Fi, or control voice assistants via Wi-fi and Bluetooth. The receiver already has built-in streaming services, which you can use with the free Onkyo Control App, which works for both Apple and Android.

As for connection options, you can connect game consoles, a vinyl player (there is a built-in phono stage), various devices via the USB port, and even old equipment.

With Onkyo TX-RZ50, you can enjoy content in 4K/120Hz mode (I mentioned 8K support at the beginning of the review) for modern video formats HDR10+ and Dolby Vision. And special mention should go to IMAX Enhanced mode, optimized for proper 4K HDR and Ultra HD Blu-ray processing, as well as allowing you to enjoy perfect DTS:X audio streaming.

Denon AVR-X3600H

And now it’s the turn of budget models. I want to start with the Denon AVR-X3600H as the best representative of the 9.2 receiver under $1000 segment. It is the embodiment of all the latest technological innovations in the production of audio equipment. It meets the ever-growing demands of consumers who value truly perfect surround sound and high-quality video.

Thanks to digital amplifiers for each channel, the device received 125W power at 8 Ohm or 165W at 6 Ohm, or 235W at peak and stable operation with good quality indicators even with low impedance acoustics. This offers the opportunity for some savings when choosing a home theater speaker.

The AVR X3600H receiver has an advanced video section with an impressive calibration set of compatibility with the new HD and Ultra HD TV panels. The unit provides multi-channel audio transmission directly from the TV panel over the extended eARC audio channel. It incorporates image optimization technology – Dolby Vision, supporting dynamic brightness expansion – HDR version 10 and HLG, which provides clarity, brightness, and remarkable detail.

Besides, the support of Dolby Atmos and DTS surround sound technologies is implemented in the device, completely immersed me in the thick of events taking place on the screen with the realistic soundtrack. I liked that it creates a pretty real immersive experience.

And I can even argue that the sound quality is at the level of premium models, and the sound is close to ideal, both when watching a movie and when listening to music. The 32-bit DAC of the top brand AKM AK4458VN by the Asahi Kasei Microdevices provides impressive processing power, which allows it to produce a good sound, I cannot say the same for the Denon AVR-X3700H.

Onkyo TX-NR797

And the last one on my list is the Onkyo TX-NR797. This is the first Onkyo receiver to be released under the IMAX Enhanced program.

In addition, this device is THX Select certified, compatible with Dolby Atmos and DTS: X audio formats, as well as 3D sound virtualization technologies, enhanced audio distribution, and 4K HDR support. That is why it plays surround sounds in 5.2.4 channels or 7.2.2 rear envelopes and develops 100W at 8 Ohm, or 220W at 6 Ohm. And this is the standard set for this price range.

TX-NR797 provides immersive DTS: X audio decoding, optimized to perfectly reproduce the full dynamic range of IMAX audio mixes.

This new IMAX Enhanced mode is designed to reproduce IMAX audio, as the filmmakers originally intended. It’s perfectly in sync because the enhanced IMAX audio has been programmed to handle 4K HDR and Ultra HD Blu-ray properly. And I must tell you that the technology fully copes with its task. There were such sensations as in a professional cinema when watching a movie, and the sound environment was fully felt.

On the other hand, the playback of audio recordings did not make such an impression on me, but still – the receiver sounds good. I cannot single out any apparent flaws in the sound. I can say for sure that the sound stage is wide and the sound itself is pretty detailed.

Premium 9.2 Receiver Reviews

Marantz SR7015 – premium

Now we will talk about receivers from the premium segment. The Marantz SR7015 is one of those. This model organically combines the signature features of the appearance in its large body, and the competent implementation of the front panel gives it harmony. In the center is a small round display with a switchable blue backlight, on which, frankly, it is difficult to discern anything. It most likely carries more of an aesthetic load than a functional one. On the sides of the display, there are two selectors with basic functionality: the volume knob on the left and the input selection on the right.

In my opinion, such display design is deliberate because apart from the menu, which SR7015 can display on the TV screen, there is another bigger and much more informative display hidden behind the flap on the front panel. You can also access some function buttons and “hot” connectors there: USB port, HDMI, headphone and microphone jack for the audio autocalibration system, and three RCAs for analog audio/video signal.

The SR7015 has a huge number of inputs and outputs, as it befits a top-level receiver. Let me immediately specify that Marantz SR7015 has 11 pairs of terminals on the rear panel to connect the speakers, but there are 9 amplifiers inside. The processor can process all 11 channels of surround sound, but only nine will sound simultaneous, depending on the surround mode set and the specific configuration chosen. If you need to use all 11 channels simultaneously, you can use the amplifier with a loop-through channel. It is also possible to activate the Bi-amping mode by reassigning a pair of built-in amplifiers to help the main speaker.

The Marantz SR7015 has eight HDMI connectors for incoming and three for outgoing signals. One of the HDMI inputs and two HDMI outputs support 8K/60Hz and 4K/120Hz video resolutions. One of the outputs also has eARC support. All other HDMI outputs support 4K/60Hz and many other useful protocols: HDR10/10+, HLG, Dolby Vision, ALLM, VRR, QMS, and QFT. Of course, there are optical, coaxial ports, and others for connecting the old equipment, but I won’t dwell on them. Crowning the back panel are two antennas on the sides – for interaction with devices via dual-band Wi-Fi (including support for Apple AirPlay 2) and Bluetooth.

HEOS multimedia technology provides a convenient control app and access to various music services: Spotify, Tidal, Amazon Prime Music, and more. In addition, the SR7015 works with Amazon Alexa and Google Assistant voice assistants as well as Siri, thanks to AirPlay 2. As a result, you can “ask” the device to play your favorite music, turn up the volume, skip to the next track, switch inputs, and more.

As for surround sound, this “universal soldier” supports Dolby Atmos, DTS:X, and Auro-3D formats (with up to 11.2 channels processing capability) and is IMAX Enhanced certified.

I think it’s important to mention that Marantz does not change its traditions in terms of sound. HDAM modules have sworn Marantz for 25 years, and it is not without reason. In Pure Direct stereo mode, the SR-7015 has a typical Marantz warm tone that is immediately noticeable. The same sound that I know well since.

Switching to Multi-Channel Stereo mode, the source, of course, remains stereo, but the sound is distributed throughout the room through all the speakers, showing that the Marantz SR7015 can produce a very believable simulation of multi-channel sound what the Denon AVR-X4700H lacks. It may not be entirely realistic for an audiophile, but it is immersive and delightful. Here I can note an even wider sound stage. Sound objects move naturally. In Cinema mode, voices are even more profound and richer.

Buyer’s guide

How much power per channel do you need?

An essential step in choosing a receiver is to determine the required power. This is a delicate point to which I draw your particular attention, as lack of power affects the final perceived sound quality.

And the first thing to do to determine the required value is to look at the impedance of the speakers we are going to install and select the receiver power we need based on that impedance.

For example, values ​​between 120 and 150 watts per channel are generally sufficient for powerful and impressive sound in rooms less than 30 square meters. They are influenced by many more factors, such as speaker sensitivity, room acoustics, etc.

Pay attention to your connections

Another key point when buying our receiver is to see what types of connections it has and in what quantity. Usually, there are many analog and digital inputs, the latter being optical and coaxial or HDMI. However, it is always advised to think about how much equipment we want to connect (DVD, Blu-ray, game console, DTT receiver, computer, TV, etc.) and with which type of connection more or less to calculate the inputs and outputs that we need.

How to add music to other rooms?

And I will mention another helpful feature that I find very useful – this is multiroom. Multiroom allows you to connect a second set of speakers (some models have support for multiple stereo pairs and a 5.1 set) in a different room that can play content independently of the primary audio source. Modern receivers can do this using a wired connection through dedicated channels. In addition, there are wireless technologies such as HEOS or AirPlay 1/2 with which you can create a multi-room environment.
