In 2020 I purchased a complete Home Theater from Best Buy, and got a Samsung Neo QLED TV, Bowers and Wilkins 5.1.2 speakers, powered by a Marantz SR7015. The 7015 was a horse for a few years, but the last few years I began having a myriad of issues. Long story short, after 4 years I took it back to Best Buy (protection plan on it) and replaced it with the Cinema 40. OMG after I connected it and ran Audessey on it, I cannot believe how MUCH BETTER the sound separation is in my 5.1.4 setup. Clarity in dialog, power in the bass (that the SR7015 can't match) and distinction from all 9 speakers. Setup was no different from the SR7015 and the remote is top notch. I'm going to get another one for my smaller room upstairs, and I don't want to drop down to the Cinema 50. I HIGHLY recommend this product, it is top notch and for the size of my room, it's perfect.

Hi there. I have been on a long journey. I have had tried many receivers by denon, the x2700h, x3800h, x4700h, and the Cinema 50 by Marantz. The Denon x4700h was ok, out of the Denon’s, but felt clunky and slow, and not like it was a new receiver. It just acted old. And the Denon’s just didn’t sound right turned all the way up. The x4700h was the best for the Denon’s at high volume, the x3800h was terrible. So I went back to the drawing board, decided to change brands, and I moved on to the Marantz Cinema 50. I didn’t know there was a Cinema 40 at the time. I loved the sound that came with the highs with the Cinema 50, but the one problem I was having with the cinema 50 was the bass. It just wasn’t to my tuning. It was lacking. Maybe you could describe it a no deep deep rich bass sound, there was definitely plenty bass, just bass that wasn’t up to par in sound to me. So I went back to the drawing board again and did a lot of studying on the Cinema 40 by Marantz. I found it was better with the separate pcb boards and amplifier, and better parts, but everyone said they would sound the same. At the time you had to order it to store. So finally got it. Hooked it up and could immediately hear the music difference in everything including the bass. They didn’t sound the same at all. I did add 3 Panamax M8 AV PRO power conditioners with high capacity outlets, one for amp and two for two subs and boy the bass jumped even higher. I could t believe how much, and how different the cinema 50 and Cinema 40 with music. I am running a Kef Q750 in front, Kef Q650c in center, 2 pairs of Kef Q150 for surround and rear heights. I have RP500SA Dolby Atmos for front heights, and 2 svs PB1000Pro subs placed in front and back corner of the room. Handles all kinds of music for rap, rock, all the kinds of bass, even computer generated bass, sounds great. Kendrick Lamar’s Swimming Pools sounds great. The Cinema 40 receiver has been my favorite of all out of the denon and Marantz receivers. It is very well built, and not as buggy like with setup with the Marantz Cinema 50. Maybe they have the calibration on the Cinema 50 has improved since update, but had all types of trouble with the setup of the Marantz Cinema 50. The Marantz Cinema 40 sounds better, is made with better parts, and I feel is the one to get, at least for me, over the Cinema 50 if you want true good sound, get the Cinema 40. Absolutely love the Marantz Cinema 40. The bass is even set at -8.5db on the Cinema 40 for both subwoofers, and the Cinema 40 has that certain sound the cinema 50 does not have with the Cinema 50 with both of my subwoofers set to 0db. I haven’t gotten Best Buy to come calibrate the Cinema 40, but did have them come out and calibrate the Cinema 50, and it just didn’t work for me. The Cinema 50 is a good receiver, but no where near the Cinema 40. They knocked it out of the park with the Marantz Cinema 40. The Denon’s don’t even compare to the cinema 40. With the Cinema 50 the bass is better on the Denon’s, but the high’s sound better on the Cinema 50. I love the Hdam SA 2 on the Cinema 40. If you want a inside look there is a training video with Marantz people on the cinema 40 on YouTube is about a 1 hr long. The first half hour is all about the upgrades, then there is just a thing on audyssey, you’ll learn but the good parts are the beginning and end, and there is Q&A at the end that really tell you about the cinema 40 and all of its features. I hope this helps you decide what you might like and for your system. As for me it is Marantz Cinema 40 all the way. It is a total Night and day difference between the Marantz Cinema 40 and the Marantz Cinema 50. It is totally worth the extra $1000, without a doubt. It has been the sound I have been searching for with the Marantz Cinema 40. I feel my journey is done. Even when the Cinema 30 comes out soon, I will stick to this, can’t sound better spouse to compare to the sound of the SR8015. I have all the power I need now, and if I go up to Kef reference series, I can just add a additional amp, and adding a amp is spouse to make the new Marantz Cinema line sound even better. The bass in the in the Cinema 40 though I feel can not be matched with the Cinema 50 at all or even the Denon’s with my setup. Saving up for the new Dirac. Spouse to make it sound like the best of audyssey setup, but 10x better if I understand. Really like my Marantz Cinema 40. Is the best receiver right now out of all of the receivers I have had. The Cinema 40 is better than all of the receivers I heard at Best Buy. I have been using Tidal as a music streaming service through heos. Tried Amazon unlimited, but wasn’t as good. I love my new Marantz Cinema 40. Sounds great.

I had a Marantz 6014 that took a power surge through my line conditioner (15) years old that i was very happy with.Now its junk!! The new cinema 40 was a huge difference in sound quality and interface.i love the changes to the menu system that simplifies the normal day to day setting changes that i do.I just hope the power supply unit inside is better than the old one.
