Marantz AV7703 review & specs

Another of Marantz family: Marantz AV7703

Marantz AV7703

Marantz AV7703 is a quite good choice for several reasons: works with Alexa for voice control, has built-in Bluetooth and dual-band WiFi, supports Dolby HD sound and can recognize 7 audio formats including DSD and WAV. However, this is nothing compared to 8 HDMI inputs (including 1 front) and 3 outputs with full HDCP 2.2 support that it has, taking into account that it requires about 0.2W standby power consumption. Extremely good quality/price ratio, all specs needed for the accessible price. Want to know more about Marantz AV7703? Have a look at the review below!

Modern design and black color make the receiver a good match to any kind of TVs, especially the smart ones that are currently popular on the market. In front, there are two main wheels - volume on the right and input selector on the left. The power button is located in the left corner that is typical for a lot of Marantz models. The device has a display to show the user all functions that are currently in use and when Marantz AV7703 is standby, time is displayed. From unique features here, there are single HDMI input, one USB and one micro-USB ports located on the front.

Also, it has the blue light on the front that indicates the working state may annoy some people. For me personally, it is not a problem, however, some people that are really sensitive towards bright colors may find it an issue. This receiver is massive compared to other ones, so please be aware of its size beforehand.


The signal-to-noise ratio of Marantz AV7703 is incredibly low - 105 dB (NB lower the value, better the receiver is). Little display in the middle with a time on and functions currently in use is clearly seen at any time even from several meters. Another pleasant thing is that this device has all these features with an operational power consumption of only 180W whereas in standby mode - only 0.2W. Output power per channel is about 100-120W which sustains a frequency response of 10Hz-100kHz.

Sound Quality

Sound quality here is absolutely insane! Total harmonic distortion is just about 0.08% which means that your sound will be clear all way through you use it. Built-in decoders of different DTS-s and all latest Dolby Digitals (including famous Atmos and Surround) ensures Audio D/A conversion at 24bit/192kHz. The 11.2 channel Surround system class with Theater-Dimensional Virtual Surround turns your house into a real cinema with 3D Volume sound all around. Just imagine how it is to enjoy a clear sound without any noise at a reasonable price.


Marantz AV7703 has 7 AV inputs, 2 optical and coaxial digital inputs, 8 HDMI inputs and 3 HDMI outputs. Please, be aware that it doesn’t have either coaxial or optical digital outputs. However, the device also has a port for a USB stick and a mini-USB port so you can enjoy listening to music from your phone. If you though don’t wish to leave your phone away from you for a long time, you can easily connect devices via Bluetooth, WiFi or IEEE 802.3/IEEE 802.3u. So, you will never face a situation when you can’t plug something in because there is no space or have to face the choice between charging the player the room or listening to the music for a little while.


Marantz AV7703 offers the automated setup of sound levels that helps a lot all the beginners who don’t know where to start from. However, setting up speakers through Audyssey setup may be a challenge, the best solution here that I found is connected speakers via XLR and then add XLR attenuators on each pre-out. In order to get a true 4k HDMI that you will enjoy, ensure that the PC input has the i/p Scaler = OFF and, if necessary, Video conversion = OFF as well.


Marantz AV7703 is quite a good choice for those who look for old-fashioned values like high-quality sound and lots of inputs and outputs available. It would not be a perfect choice for someone who looks for a compact receiver with a phone remote control option and newly Dolby Digital Plus, however if you decide to get Marantz AV7703 you will get real benefits in terms of ease of setup, ability to connect HEOS speakers that can be quite far away and quite low power consumption.
