Anthem is one of our most favorite home theater brands at Audio Advice because their products just sound so good for the money and Anthem puts all of their emphasis on giving you the best possible home theater experience.

We were lucky enough to be part of the Anthem beta team to test out and have an advance look at their new products launched in late 2020. Due to a fire at a parts supplier for some of the components in the AVM90, it was delayed. This delay did have a silver lining as Anthem was able to come up with some improvements to make it even better than they originally envisioned. We just got our hands on one of the first models to make it to North America and have a separate video just on the new AVM90.

If you are reading this, you are likely pretty serious about getting the best possible home theater sound. As you probably know, separate home theater components put the audio processing and switching in one component with the power to drive your speakers in either one or more amplifier boxes. This separates the low level signals from the high level signals giving you cleaner sound, plus the better amp sections found in separate power amps usually deliver far more performance than those in even the best receivers.

Anthem revamped their highly successful AVM60 processor into the AVM70 and added a new no holds barred processor with the AVM90.

Their MCA series of power amps have always been outstanding audio values for the sound they can deliver for the money. With the new series 2 versions, Anthem has made some pretty big changes for even better sound. We will go over those in a separate review.

Anthem upgraded all the models to have the industrial look of their STR two-channel products. Now, all of the pieces look perfectly matched and you can even combine the power amps with any of their home theater receivers and they are an exact cosmetic fit.

Now, let’s take a look at the new processors and what they have in common.

More Channels for Immersive Audio

At Audio Advice, we just love immersive home theater audio. When Dolby Atmos and other object-based surround formats came on the scene a few years ago, we were just totally thrilled! Dolby Atmos for the home maxed out at 11 channels plus subwoofer(s) until just recently. You can now find 9.4 and even 9.6 Dolby Atmos configurations guides on the Dolby website.

For larger spaces, this is pretty cool as the 8th and 9th lower channels place speakers on the side walls in front of your between your side surround speakers and your left and right front speakers making the soundfield even more seamless! And with 6 Atmos height speakers, the height effects will go to a new level!

We were so happy to see the new Anthem home theater processors go all the way to 15 channels plus subwoofer outputs. This means you can take your home theater to new levels of audio immersion. Plus both models give you a complete set of both balanced audio and RCA outputs for every single channel!

New Streaming Platform

Anthem had relied on DTS PlayFi in the past, which was ok, but we were pleased to see them move to Chromecast, Airplay2, Bluetooth, Spotify Connect and an upcoming update will add Roon. At Audio Advice we are big fans of Roon as it is just such a great way to discover new music and ties in Tidal, Qobuz, and your library all into one beautiful interface.

Built-In Phono Preamp

Both the Anthem AVM70 and AVM90 now include a built-in moving magnet phono preamp. This is no afterthought either as the engineers spent some serious time developing a great moving magnet phono stage.

All the Formats

Both surround sound processors have decoding for Dolby Atmos, DTS:X Pro, and IMAX Enhanced. These are somewhat competing formats for mixing the audio tracks of movies. Dolby Atmos is the most widely adopted and has clear guidance on where to place your speakers. IMAX enhanced uses DTS which can adapt to various speaker layouts. The great news is, no matter how that new movie was mastered or that classic one was remastered, the two new processors have you totally covered no matter how the soundtrack was produced. And for those of you using a TV capable of Dolby Vision, you will be pleased to know these two units also support Dolby Vision as well.

8K Ready

The AVM90 ships with HDMI 2.1 full 8K video capabilities built in. Anthem tells us there will be a future hardware update to take the AVM70 to these boards, but they have not announced a price on it yet.

8K may or may not be a big deal for you. If you have a TV capable of 8K, you could connect your 8K sources to it and send the audio back down the HDMI e-ARC connector on your TV. The fact that Anthem added an e-ARC input to the AVM90 and AVM70 makes this work-around possible. Almost all recent TV’s are e-ARC compatible and e-ARC allows for a fully uncompressed object based surround audio signal to pass through, which is pretty cool.

30 Virtual Inputs With Great Lip Sync Capabilities

Both units have 7 HDMI inputs, 3 Toslink digital, 2 Coax Digital, 4 Analog, plus the MM phono preamp. There is also a new e-Arc HDMI connector so you could get a full Dolby Digital signal back from your TV if your like to use your TV apps. Both also have zone 2 audio and HDMI outputs.

Most home theater products lock you into using an HDMI input only once. Not so with Anthem. You can create up to 30 inputs using any combination you wish. Think about watching a sporting event and tuning into the local radio station. Or, you could listen to music while casually watching the stock reports or a news feed.

Some of you who are serious listeners may have noticed there is a bit of difference in lip sync between streaming platforms. Lip Sync problems occur when the audio arrives ahead of the video. Adjustable lip sync at the unit doing the video switching allows you to adjust for this. We even have a lip sync calibration video to help you get to a good starting point.

Another super cool feature on the Anthem AVM70 and AVM90, is the ability to assign a different lip sync for each input, with the range of adjustment from 0-500ms which is very wide compared to some other products. If you are using a home theater with a separate video processor after your AVM, like a madVR Envy or Lumigen, you will really need this as video processors add a delay to the video of around 200-250ms and that is before any delay caused by the streaming source.

So if you get creative, with the virtual inputs, you could set one up for HBO Max, another for Netflix, another for Hulu, and more- all using the same HDMI connection and then set up the different lip syncs for each streaming source and even label that input to be the name of your streaming source. How cool is that!!!! We really love the flexibility this offers.

Web Setup Interface

If typing in 30 names of your virtual inputs using the cursor makes you think that is going to be time-consuming, you’ll be super pleased to know about the great new web interface. All you have to do is download the free software from Anthem, look up the IP address of your processor, (which you can find by selecting the network display) then you have full access to every single part of the setup right from your laptop! This also means you can sit in your primary listening position and quickly fine-tune the settings to really dial in the audio if you wish.

Anthem Room Correction

This is one big reason we love Anthem gear. The room correction they developed called ARC is simply one of the best on the market. The room itself has a tremendous impact on the ultimate sound of your system. The problem is every room will cause certain frequencies to be too loud and others to be canceled out.

Anthem Room Correction takes measurements of the room and smooths out the response. The new version launching concurrently with the AVM90 adds even more great features to better blend subwoofers to main speakers plus perfectly set distances and levels It does all of these in a way that it has no impact on the phase of the sound like some room correction does, and the result is extremely impressive.

Anthem’s latest version of their system is called ARC Genesis. We have found from using other room correction systems that the quality of the microphone can have a big effect on the end result. Anthem was totally aware of this as well and required you to download a config file from their site matching the calibration characteristics of the exact microphone you were going to use.

Luckily for all of us, they knew they could make things even better and set out to completely redesign the microphone they use for ARC. They even designed it to be directional so it would know better about sounds coming from every direction. The new microphone looks much beefier and has a little indicator you will need to point exactly towards the front of the room. This is just so cool the way they push the envelope!

We are very excited about the tech Anthem is using in the new version of ARC Genesis to blend the subwoofers with your speakers. It is pretty easy to use a tape measure to get the distances correct on your main speakers, but nailing subwoofer blending has been a task that can take some work. Most subs add some delay through their built in amp and it was a bit of trial and error in the past to get them aligned. ARC Genesis now makes this simple and goes a step further by looking at the phase response of both your main speakers and subs to make them sound like one cohesive unit. This is just such a great feature we know all home theater enthusiasts will really appreciate.

And speaking of subwoofers, ARC Genesis now gives you the option to run your main speakers’ full range and send bass to a subwoofer at the same time for those audiophiles who prefer their left and right speakers to just roll off naturally.

Another part we like about ARC is the fact it has 4 presets. This means you could set up one room correction for the best sound at your own favorite seat. You could do another for 2-4 people, another for a room full of guests, and another for late-night listening with your subwoofers turned down or off. And along with these 4 ARC presets, they also have full adjustments for level, crossover, and distance for each one. That is just so great!

Upgraded Cosmetics

Anthem took the great look of their STR two-channel separates and used it for all of the new receivers, amps, and processors this year. One big advantage we see, in addition to the fact everything perfectly matches and has a great look, is the fact the display is now 5 lines so you can actually do quite a bit of setup right from the front panel easily if need be.

Well, with all of these great features built into both units, you may be wondering why you would need the AVM90 over the Anthem AVM70. There is one simple reason: better sound!

Anthem AVM70 vs Anthem AVM90

The Anthem AVM70 gets an upgraded set of DACs over those used in the Anthem receivers. Coupled with the low noise toroidal transformer the AVM70 gives us a big improvement over the previous model. The DACs are 32 bit/768kHz which is pretty impressive on its own.

The Anthem AVM90 goes to a much better set of DAC’s. They use very high end audiophile level DAC’s, that while they have the same spec at 32bit/768kHz, they are far superior in sound. This is one of the improvements that came from the delay in the initial shipments of the AVM90. The Anthem engineers had more time to evaluate all of the best DAC’s available. We can tell you from our listening tests, this unit sounds as good as many high end audio stereo preamps. With the AVM90 your sound will be smoother and sweeter with deeper bass extension and a more effortless presentation. If you plan to use your home theater for music listening, you will definitely appreciate the great DAC’s in both of these units, but the AVM90 is a substantial jump up in audio quality.

Overall Recommendation

Anthem processors have always done a fantastic job at spatial imaging. They can locate effects in precise positions with special effects panning across or around the room sounding totally natural. With the better DAC’s and improved power supplies on the new models, they are even better. The Anthem AVM60 was an amazing value and with everything you get now in the upgraded AVM70, it is an even better value.

The question comes down to, is the AVM90 worth double the price of the AVM70? For most people, the AVM70 will be a perfect fit and offer excellent sound and spatial imaging in a great home theater. But if you are really serious about music listening, the much better DAC’s in the AVM90 will offer a big upgrade for your two-channel listening.

Or, if you have always wanted more than two subwoofers but could not find a processor under $20K to handle them, you will be as happy as we were when we saw the AVM90 has 4 independent subwoofer channels.

And better yet, if you are a serious music listener and want 4 subwoofers for your ultimate theater, the AVM90 becomes a no brainer!
