The MRX 740-8K is the successor to the best-selling Anthem MRX 720 Home Theater Receiver. This is the model we think will be our most popular one. It has seven powered channels built-in, offering 140 watts per channel. The amp section is a lot beefier than the MRX 540 so you will get better dynamics and speaker control with the MRX 740.

High Notes

Anthem Room Correction

Your room has a bigger impact on the sound than any component in your system. Anthem's new ARC Genesis is an easy to use room correction system that gives your sound a huge improvement. ARC takes out all the big peaks to let you hear your home theater and music soundtracks the way the engineers intended.

Real Power with Great DAC's

Anthem receivers have a big, full warm sound due to the fact they have massive power amps inside, actually similar to what you might find in some separate amps. They have a drive and control that makes your speakers come to life. Add in the fact they use audiophile level DAC's for all decoding and you have a receiver that sounds just amazing.

Outstanding Flexibility

With 4 speaker and ARC presets for various listening situations, 30 virtual inputs, 15 channels of processing on board with power amp matrixing and discrete dual sub outs, the MRX1140 covers a lot of bases. We love the fact you can rearrange 10 of the 11 built in channels and add a big separate amp for the fronts and get 15 plus two sub channels of great object based surround.

When we get above $2,500, the flavor of things changes. You’ll start to see units from companies that focus their efforts on the best sound possible. If their engineers have to decide between paying royalties for Alexa voice control or putting in better parts, they will always opt for the better parts.

The Anthem MRX 740 is all about great sound. We have found two things are probably the most important in how good all of these receivers sound — it's the amplifier portion and the digital portion that does all the signal processing. Anthem has put the same type of technology into their receivers as they do in their big separate power amps with massive power supplies that offer your speakers huge current reserves.

On the digital side, Anthem uses a quad core processor to extract every nuance of object-based surround information, then the signal is decoded through premium 32-bit / 768 kHz Differential-Output D/A converters. This is far better than found in most receivers and the result is sound that totally envelopes you.

Another thing you get with Anthem receivers is their famous Anthem Room Correction or ARC Genesis. Each unit comes with a professional-style calibrated microphone with a file for that exact mic. You do not have to buy a better mic as the one included is excellent and was even upgraded in 2021. Anthem Room Correction is now as good or better than Dirac as they have now given it the ability to blend your subwoofers and set levels and delays. It is also extremely easy to fine-tune all of your speakers to your listening room.

We also love the way you can set up four different profiles for room correction. Think of one for a single listener, one for a crowd, and one for music only. Super cool!

You also have room to grow into a full-blown 7.2.4 Dolby Atmos system with preamp outs on the MRX 740 for future power amps — and taking things to a level no other receiver does, you can reroute amp channels. Let’s say you need two more channels to go from the included recommended option of 5.2.2 to 5.2.4. You can purchase a great two-channel power amp for the main two-channels and use power amp matrixing to re-route those amp channels to drive any other two-channels.

Anthem also has almost everything covered on the video side with Dolby Vision, HDR, IMAX Enhanced, and the 2023 model supports 8K video. Music streaming is also very seamless with Airplay2, Chromecast, and Bluetooth.

But, it's really the sound of the Anthem receivers that win so many people over. While the MRX740 may only have 7 powered channels on board, it weighs more than any receiver on this list so far due to its massive power supply. The sound is more like what you get from separate components with dynamics that make your system really come to life.

We’ll never forget the first time we installed an Anthem MRX receiver in our showroom. This particular theater room has the gear all hidden away, and we did the installation and the calibration without letting anyone know we had changed things. Within just a few hours, our staff was doing demos and asking what the heck we did to the room as it just sounded so much better!

When you want great sound and only need 7 channels for now, but with room to grow, the Anthem MRX 740 is the best choice.
