There are very few differences between SR6013, SR6012, and SR7012 such as the SR6013 being IMAX Enhanced-ready and having DTS Virtual:X processing out of the box whereas the SR6012 and SR7012 are not IMAX Enhanced-ready and require a firmware update for DTS Virtual:X. There is also some variation in the number of connections and front panel buttons on the SR7012 vs SR6012 / SR6013.
In terms of power output, they are all rated at 110 Watts per channel (2-channel driven into 8 ohms, 20 Hz - 20 kHz, 0.08% THD). Furthermore, they all have 9 amplifier and 11.2 pre-amp/processing channels which leads to the same Dolby Atmos configurations being supported by either SR6013, SR6012, or SR7012. Specifically, they have the built-in amplification to drive up to 7.1.2 or 5.1.4 channel Dolby Atmos speaker setup. If you utilize their 11.2 channel processing capability by adding an external 2-channel power amplifier, though, then you can have up to 7.1.4 or 9.1.2 channel Dolby Atmos. The three Marantz receivers also support DTS:X. When it comes to Auro-3D, however, only the SR7012 has a decoder for this format, and is able to natively power up to 9.1-channel Auro-3D speaker systems (10.1-channel Auro-3D is possible with an external amplifier connected to the Subwoofer 2 pre-out). The SR6012 and SR6013 omit the Auro-3D decoder, so they only support Dolby Atmos and DTS:X as far as three-dimensional audio formats are concerned.
The SR7012 supports 3 multi-room zones, and has dedicated 2-channel pre-outs for Zone 2 and Zone 3. The SR6012 and SR6013, on the other hand, support 2 multi-room zones, meaning that they only have dedicated 2-channel pre-outs for Zone 2. Either one of the three Marantz receivers has 11.2 channel pre-outs for the Main zone. The 2 subwoofer outs are independent which allows discrete subwoofer functionality. Furthermore, thanks to the Audyssey Sub EQ HT, which is part of the Audyssey MultEQ XT32 suite of acoustic room correction features all three Marantz receivers are equipped with, it's possible for each one of the two subwoofers to be individually DSP-tailored. While on the subject of Audyssey calibration, it should be said that there is a measurement microphone included with either SR7012, SR6013, or SR6012, and you can use it to record the speakers response at up to 8 different locations after which precision digital filters are generated in order for the frequency and time domain response to be optimized based on the room acoustics.
The SR6013 and SR6012 have the same number of connections. The I/0 layout is also identical. In contrast, the SR7012 has some additional connections in comparison to the SR6012 / SR6013. For example, there are 2 composite video outputs on the SR7012 vs only 1 on the SR6013 / SR6012. The SR7012 has 3 component video inputs vs 2 such inputs on the SR6013 / SR6012. The number of DC out jacks is also different: there are on 2 on the SR7012 while the SR6013 and SR6012 have only one 12V trigger output. The rest of the connections are the same for either one of the three Marantz receivers, including 7 HDMI inputs on the back and a single HDMI input on the front, all of which are HDCP 2.2 compatible. Furthermore, all three receivers support Dolby Vision, HDR10, and HLG (Hybrid Log Gamma) pass-through. The SR7012, SR6013, and SR6012 have three HDMI outputs, one of which is for Zone 2. ARC (Audio Return Channel) is supported on one of the two HDMI outputs for the Main Zone, and all three receivers will receive a firmware update for eARC (Enhanced Audio Return Channel), according to Marantz, in order for the pass-through of Atmos tracks from your TV's internal apps to be possible, even if a lossless audio codec such as Dolby TrueHD is used for encoding them.
Although any of the three Marantz receivers has a circular display on the front panel, it needs to be said that the SR6013 and SR6012 omit the second display and the buttons (i.e. 4-side cursor, enter, back, and setup) accompanying it that can be found behind a cover on the SR7012's front panel. The SR6013 and SR6012 also lack the Dynamic EQ and Dynamic Volume buttons which are placed to the left of the SR7012's second display. While there are dedicated buttons for Movie, Music, and Game sound modes on the SR7012, there is only a single button for Sound Mode selection on the SR6013 and SR6012. Another buttons that can only be found on the SR7012 are Information, HDMI Out, Speaker A/B switching, and Zone Select but there are no Zone2 Source and Tuner Preset Channel Buttons on the SR7012 whereas the SR6013 and SR6012 do include them. Some of the front panel buttons are the same for all three receivers, though. For example, Pure-Direct, M-DAX, Zone 2 On/Off, Dimmer, and Status. The front connections are also identical on either SR7012, SR6013, and SR6012.
The SR6013 and SR6012 have the same remote which differs from the SR7012's remote in that it lacks the three operation mode light indicators, in addition to device and TV operation buttons that are near the top of the SR7012's remote. Furthermore, the SR6013 / SR6012's remote omits the number buttons that are placed near the bottom of the SR7012's remote.
