Video & Exclusive Formats
On HDMI you get the same 6 inputs, but on the 50 all 6 support that full 8K at 60 hertz and 4K at 120 hertz pass-through, and you get 3 outputs instead of 2, two of those running in parallel for a TV and a projector like the 60, plus a dedicated Zone 2 output that can feed a completely different source to a second room. You also get Auro 3D and IMAX Enhanced, both exclusive to this model, along with 360 Reality Audio and MPEG-H.
Dolby Atmos Channel Expander
There's also a new feature exclusive to the 50 called Dolby Atmos Channel Expander. A lot of channel-based Atmos content, think live sports or cable broadcasts, isn't mapped to your specific speaker layout, and without this, overhead information can end up parked on just one height position while the rest of your height speakers sit idle. Channel Expander spreads it across your whole height array instead. It's limited to 9-channel-and-up receivers for a reason, you need enough height positions actually installed for there to be anything to spread across, which is exactly why this is a 50 exclusive.
Room Correction & Build Quality
Room correction steps up to Audyssey MultEQ XT32 instead of the 60's base XT, plus Audyssey LFC, a low-frequency containment feature that reduces how much bass leaks through walls and floors into other rooms of the house. Dirac Live continues here exactly as it always has, still an optional paid upgrade, but it's the one that gets the full suite, Room Correction, Bass Control, and Active Room Treatment.
Build quality steps up too, with gold plating on both the RCA jacks and the speaker binding posts, a clock jitter reducer the 60 doesn't have, and a full metal front panel. Series 2 also brings Center Bi-Amp Mode exclusively to the 50, on top of the front left and right bi-amping both units share, so the center channel can get its own dedicated amplification too, particularly handy if you're running a simpler 5.1 setup on the 50's 9 channels and would rather put those extra amps to work than leave them idle. There's also the amp routing option, where you can add an outboard 2-channel power amp and assign it to your front mains, your rears, or a single pair of Atmos speakers.
With everything this unit does, from the 4 independent subs to Auro 3D and IMAX Enhanced to that extra layer of room correction, this is still the one that's tough to beat at its price point. It's priced at $2,800, the same as the original.
Is It Worth Upgrading?
If you already own an original Cinema 50 or 60 and you're happy with how it sounds, we wouldn't rush you into replacing it. The amplifier section, the channel count, and the processing are all unchanged, so you aren't losing capability by holding onto what you have.
Series 2 makes the most sense if you're buying new and want the most refined version of the platform, or if that DAC upgrade matters enough to you to justify it. The Cinema 60 is the one worth a closer look. If Dirac Live was ever the reason you considered stepping up to the 50, Series 2 just removed that reason. And since both units are priced the same as their predecessors, you're getting everything above without paying a premium for it.
What About the Cinema 70s?
Marantz gave the Cinema 70s the same core update: an upgraded 32-bit, 8 channel DAC and a new optional Dirac Live Room Correction upgrade path it didn't have before, all while keeping its 7.2 channels at 50 watts per channel exactly the same. We'll have a full review of it shortly, so keep an eye out.
