Yamaha CX-A5000 Surround Processor and MX-A5000 Amplifier Page 2

The YPAO nailed the speaker distances to within 1 inch of their actual placements. However, it set the crossover point of my front speakers to 60 hertz and set them as Large—not an ideal result, considering they are M&K S-150s, which absolutely require a subwoofer in order to properly fill the entire audio spectrum. Having the speakers set to Large also disabled the subwoofer for two-channel music, though Yamaha says there’s an Extra Bass setting to override this where desired. I manually changed the setting to Small and reassigned the crossover point to the THX-recommended 80 Hz. Furthermore, the volume levels of the surround speakers were about 3 decibels too low when measured with my RadioShack SPL meter, so I made the appropriate changes in the setup menu.

That New-Car Smell
Setting up the pre/pro is fairly simple if you’re familiar with Yamaha’s tabbed setup menus. But if you’re a novice, you may have to take a trip into the manual. While you can access the pre/pro through your home network via the aforementioned apps or directly through its IP address from a computer on your network, you can’t use them to set up the unit for the first time. Those more modern setup methods are something I’ve found handy on other units I’ve reviewed, and I’d love to see Yamaha implement them in future products. One other tiny pet peeve: You must have your display on to enter the setup menu. None of the options is available on the text-based display on the front of the unit—not a lot of fun for those of us who have to power up a front projector just to tweak a setting while listening to two-channel music.


I used two different amplifier setups in my evaluation: my reference Parasound A 51 and A 23 combination in a traditional 7.1 configuration (to see how well the controller mated with amps that I know really well) and Yamaha’s matching 11-channel MX-A5000. The spec sheet states the Yamaha will deliver 150 watts per channel with two channels driven, but like with a lot of products, it doesn’t state what the amp will do with all channels driven. Still, my experience causes me to doubt the amp will deliver anything close to the specified power with even seven channels driven (see the Test Bench for its true power capability). Even though mass has no direct relationship to power output, it’s sometimes an indication of the heft of the power supply. At 56 pounds, the MX-A5000 is a lightweight compared with my 80-pound A 51, which has only five channels.

Despite its somewhat pedestrian specs and weight, the MX-A5000 has an overall build quality matching that of the CX-A5000, and it offers a number of customizable options. With 11 channels to play around with, you could run a conventional five- or seven-channel setup in your main listening room and use the extra amps to power a couple of two-channel zones elsewhere in your home. Or you can biamp up to five channels of speakers in your main listening room if your speakers offer that capability. Or you can go big and power all 11 speakers in one room with the addition of the two front and two rear height speakers. So whereas having all of your amps in one box means you may give up a little power per channel, it also means you get more convenience.

Cool Kid on the Block
I used the CX-A5000 for nearly a month, and the first thing that struck me—besides the great sound—was how cool the pre/pro was after extended use. In fact, it never got over 100 degrees, which is something I can’t say about my reference Marantz AV8801 pre/pro. As you probably know, overheating of electronics is never a good thing for their longevity, which is why I installed custom fans in my rack to keep all my gear under the century mark.

Friends is one of the best sitcoms in the history of television, and my wife and I have been revisiting the series on Blu-ray with our teenage kids for almost a year now. While the Yamaha was in the rack, we were on season 8. Customarily, a sitcom isn’t demo-worthy material, but in the episode “The One Where Joey Tells Rachel,” there’s a great scene in a restaurant where Joey professes his newfound love for his friend. What struck me was the amazing ambience the Yamaha exhibited with the sounds of silverware clanking on plates, ice water pouring into glasses, and patrons chattering. It really gave me that “being there” feeling. Both sets of amplifiers excelled in this and other types of environmental effects, not only in sitcoms but also in feature-length films and live sporting events.


Star Trek Into Darkness is the second film from J.J. Abrams in the rebooted Star Trek universe, and its Dolby TrueHD 7.1 soundtrack on Blu-ray is demo-worthy for virtually the entire movie. The action scenes are filled with directional effects flying through the room, and while the bass response isn’t the deepest I’ve heard, it’s by no measure a slouch. Comparing the Yamaha amp with my Parasounds showed some distinct differences between the two solutions. The Parasounds certainly had a lot more power in the action scenes, with clearer detail in the directional effects and a more robust midrange for Michael Giacchino’s wonderful score. Granted, I wasn’t able to switch between the two setups on the fly, and it required a few minutes to rewire things, but I’m confident the Parasound combo was the superior choice and packed a lot more punch, as it should—the A 51 alone costs $4,500 and is rated at 250 watts per channel, all channels driven, versus the Yamaha’s 150 watts x 2 rating and $3,000 price tag. So it was no surprise that Yamaha’s amp couldn’t keep pace with the more powerful Parasounds. It wasn’t bad, but it couldn’t quite give the CX-A5000 its full due.

And that was a lot: The audio quality from Yamaha’s surround processor is a surefire winner. Whether it was two-channel stereo, streamed FLAC files from my home server, or multichannel tracks from Blu-ray concert discs, I was never left wanting for my Marantz reference pre/pro. While I really liked the audio output from the CX-A5000 with its sibling amp, I loved the combination with the Parasound amps. Imaging with two-channel stereo created a phantom center presence; you’d swear that all three front channels were engaged if you were sitting in the money spot on my couch. But the true testament to how well the pre/pro dealt with music came when I popped in the Blu-ray of Roy Orbison: Black and White Night. Intending to sample a few tracks, I ended up watching the entire disc because I was so mesmerized by the crystal-clear midrange and room-filling bass response. I toggled between the YPAO settings (Flat, Front, Natural, and Through, the last of which disables the equalizer) and preferred the Flat response because it moved the vocals more forward and gave them a tad more presence, especially compared with the Through setting (which didn’t sound remotely bad, just different and more laid-back).

It’s Hard to Say Goodbye
Living with the Yamaha CX-A5000 has been a pleasure; I hope my Marantz won’t feel like a jilted lover when it finally goes back in the rack. It’s an outstanding value, given its bevy of features and terrific audio performance, and it definitely deserves its Top Pick status. On the other hand, the MX-A5000 amplifier, while certainly scoring points for its convenient form factor and 11-channel offering, was merely competent; I found its power output a bit wanting. But that’s the beauty of living in the world of separates: You can pick and choose your parts in order to achieve the best results for your equipment. In fact, if I hadn’t just plunked down some hard-earned cash on the Marantz earlier this year, I’d have a hard time letting the CX-A5000 leave my home. Yes, folks, it’s that impressive.

Informative Review Dave. Can you expand a little more on the differences between your 8801 and the Yamaha specifically in the room correction side. I find Audyssey inconsistent but great in handling subs. How about HDMI switching? Are there any lag or loss of audio for a few seconds?

Where are the results for the amplifier output in five, seven, and possibly other channels? It looks like the amplifier puts out between 165-170 watts in stereo.

Having the Audyssey Pro in the 8801 is a nice upgrade, but if you don't have your own kit you have to pay someone to utilize this aspect of the unit. You can take a lot more measurements and really get the audio to sound outstanding. The stock Audyssey versus YPAO is virtually a tie...both sounded good in my room where the Pro sounded great. As for the HSMI switching, both units take a second or two to lock onto the signal, which is par for the course unfortunately. I've yet to see any HDMI switching to be instantaneous.

Nice review David
I read your earlier review on the Marantz AV8801 and was pretty much decided that this was the unit that I would be purchasing.
Now after reading your review of the Cx-5000 I wonder if this is the right move. Are you saying in your review that you would not have purchased the AV8801 had you seen the CX-5000?
I would be interested to know more about how you would compare the two units.

If I had seen the Yamaha first I would have had no hesitation to buy it. I was in the market for a pre/pro and it met or exceeded every expectation I had. BUT, the exact same can be said for the Marantz. I could own either one and be perfectly happy with them. It just so happens I already owned the Marantz and didn't feel the need to buy a new unit since they were pretty much equal. I would go with the one that you could get the best price on because you really can't go wrong with either one.

The Yamaha CX-A5000 replaced a Parasound C2 controller in my home theater. Like David Vaughn, I found the Yamaha to be a great match with my Parasound amps (A21 and A51) in a 7.1 system using balanced interconnects. The CX=A5000 has a lower residual noise level than my Parasound C2 and many updated features, such as HDMI inputs, YPAO, Airplay, Sirius internet, etc. I enjoy the ability to control the CX-A5000 with my iPod. The sound quality available from Airplay is surprisingly good. The sound quality from DVDs and Blu-ray in my opinion is an improvement over my Parasound C2 controller, which already was very good. YPAO functions well in my room.

Where are the complete measurements for the MX-A5000 amplifier?

I currently have a Yamaha RX-A2030 receiver driving a Sunfire TGA7401 amp. I have found some CX-A5000 units for around $1000 and I'm thinking of replacing the receiver with the CX-A5000. From what I can tell the only differences between the two (aside from the amplifiers) are the balanced outputs and the exclusive use of the 9016 DACs. Are there any other differences I am not aware of and do you think I will see much performance difference.

Hi Orcrone,

I also have a TGA 7401 and am considering the CX-A5000. Did you ever follow through and get this unit? I realize it's been a couple years since your last post. I would appreciate any feedback.

Scottieophile's picture

Looking to upgrade from Integra DHC 80.2. Is there anybody that has gone this route. Looking for feedback.

These types of comments and thinking just blows my mind. "I like Marantz better..." "I prefer Onykyo..." You can get an Anthem AVM60 and MCA525 for the same price or close. Granted the MCA is 5 channels but 7+ is a niche market anyway and the Anthem absolutely blows the doors off of the Japanese "Big 4." Glad the author called it like he saw(heard) it. I can see them competing at the sub 1000 levels but you quickly get into Anthem/Arcam territory at higher price points. Really?
