“It's been the case since day one, only works if eARC is disabled but you lose Atmos -.- really unprofessional and very unhappy so far.”

66% of 80 verified owners recommend the Marantz Cinema 50, based on real owner verdicts aggregated from Reddit, enthusiast forums, and YouTube.

Affiliate blogs here say 100% recommend, while the owner-based score is 66%. They earn a commission on every sale — so we show them for transparency but never let them move the score.
The headline score reflects owners (Reddit, enthusiast forums), independent lab tests, blogs with no affiliate links, and YouTube owner-comments when they line up with owners. YouTube and Affiliate blogs are shown for perspective but kept out here — hover the i for why.

“It's been the case since day one, only works if eARC is disabled but you lose Atmos -.- really unprofessional and very unhappy so far.”
“I tried Dirac on my Marantz Cinema 50 for the first time this weekend. The improvement over Audyssey Multi EQ was dramatic. Detail and clarity have improved to the extent that I would expect from whole new speakers.”
“The FRONT plate of the Marantz Cinema 50 is NOT plastic. It’s ALUMINUM. I own one!”
“Got a Cinema 50 for a month or so. It's not bad. Audyssey is certainly not lean sounding”
“The Cinema 50 is definitely not plastic. I have it and also it says on their website spec sheet that it is metal. It is solid and gorgeous especially in silver.”
“I have the marantz cinema 50, upgrading from denon x1800h. The movies sound quality is better, but the music is pretty bad. I think it has bad DAC, or a bad implementation.”
“All these are driving by Marantz Cinema 50. When I add last 4 speakers I lose a lot of separation and the sound when I listen is kind a washed out especially above -50db”
“I upgraded to a Marantz Cinema 50, mainly for DIRAC, but was glad to see that it had a phono input. My previous receiver did not. Anywho, it sounds like garbage. I had to use a different input and my preamp that I was using.”
“I must say I am quite impressed with it as it — significantly — opens the soundscape. A major upgrade to the my 5012.”
“Sony a90j via eARC to Marantz Cinema50 AVR. After 5-10m of gameplay, the Atmos signal becomes distorted/garbled and requires me to switch PS5 audio formats to reset it.”
“Yup, on my Marantz Cinema 50 it has no problem doing that so far! Still weird they bailed on DTS.”
“I still have the Cinema 50 and love it. I've run Audyssey on it and got good results in my medium sized room. It made the sound fuller, especially the bass.”
“I bought both the Denon X3800H and the Marantz Cinema 50 and compared them both. To my ear the Cinema 50 was clearly better for music. It has a bigger front sound stage. Its has a smoother overall sound.”
“So I had the 3800 and it sound terrible for music but really nice with tv and movies so I switched to cinema 50 and it's great for music but lacks that movie theatre feeling for me.”
“I used this movie to sound test my new Marantz Cinema 50 with a 5.1 + front two Dolby Atmos setup. I was so disappointed that I could barely hear the dialog”
“The Cinema 50 drives my R3's like a boss and sounds fantastic with 5.1 and 2 channel 24bit 96khz material.”
“I am angered every time I use my Marantz Cinema 50 because the 4k video signal from PS5/Series X might not actually turn on and I often have to flip between video sources for it to "catch" and work properly.”
“I picked up a CINEMA 50 a week ago to replace an SR7012. So far it's been mostly good. The updated GUI is great and I like the updated remote. However I've been having some audio dropout (handshaking issue...?) when using a TiVo.”
“it sounds bit fuller with more punch, but imaging is bit not focused as the internal DAC”
“At first, my new unit did not have the serious issues that are now daily issues. Seems like each day they continue to get worse now.”
“I’m super impressed with audysseys ability to flatten the curves. The system sounds amazing.”
“I have the Marantz Cinema 50. I currently only have two channels driven right now”
“I own both.”
“I had a Marantz cinema 50 but it was too buggy with cec on a Sony tv. Got a Sony Str-az5000es and haven’t looked back.”
Practical notes owners raise — setup, quirks, and issues to watch for. They don't say whether the person likes the product, so they're not counted in the score, but they inform the pros, cons, and who it's for.
“whenever I push the mute button (av remote, universal remote, or shield pro remote through ir control) the receiver doesn't remain muted. It's as though it's sending the command multiple times”
