Question about the power rating on the three front channels. Page 18 of the manual states: "...The amplifiers powering the front three channels feature a special high-current output stage for exceptional sound stage coherence and clarity." Are the 3 front channels rated at a higher watt per channel than the surrounds? 165 watts for each front 3 and 100 watts for each of the 8 surrounds? All eleven channels are the same in terms of wattage. The difference appears to be in the output buffer. |

I don't think thats the case...in their "Texas road show" they were showing new products for 2023...they had a preproduction model of the mr1 with 175watts for LCR an 100 watts for the remaining channels. I was wondering if the finished product had the same specs.

All of the amplifier channels on the MR1 are rated for the same power output into normal 4 Ohm or 8 Ohm speakers. The front three channels have extra output devices. This gives them the ability to deliver a bit more current - if the load actually demands it. It also technically lowers the impedance of the output stage a little bit before feedback is applied. As a result, while the difference really doesn't show up in the specs, those channels are a bit more robust when it comes to driving difficult-to-drive speakers. And, depending on your speakers, and lots of other stuff, you might also notice a slight benefit in terms of clarity and smoothness. Question about the power rating on the three front channels.

What are "...extra output devices"? I have B&W 702s2 speakers and in my current setup the LCR channels are at 165 watts. I don't want to lose this power if I get the MR1.

I am running 702S2 and have no issue with the MR-1 power wise. Even if you were running all 11 channels and were seeing 100w/ch the difference in output wouldn't exceed 3db unless your current amp has tons of headroom and is very conservatively rated. The MR-1 in a five channel configuration can output power to drive my 702s well beyond comfortable listening levels. The amplifier section has plenty of muscle. |

All of the channels in the MR1 are extremely powerful... And they're all rated to deliver the same amount of power under normal conditions... And they all sound really really good... But the front three channels in the MR1 are "over engineered a little bit more than the rest"... Specifically - those three channels have extra power transistors in their output sections. And, as a result, under really extreme operating conditions, they will be working a little less hard, so they may deliver slightly better performance, or sound a tiny bit better... Whether you notice a significant benefit from those extra output devices will depend on a lot of things... But you're certainly not going to lose anything because of them...

In any event, rated power will drop like a stone when all channels are in play. Even if not at 'full tilt', I'd expect a 20% power reduction to start. More as demand rises.... And power / distortion at 4ohms also comes into play, if even so rated. |

For how many channels? Is this ia 5 or 7 channel amp?
The additional power transistors Keith ref's are good for Dybamic power. This comes into play at higher levels when
you may hit a 'peak'.
What range is normal music? 10db? 20db? I don't know offhand but additional headroom even against a fixed power is very welcome....

I saw that and am just wondering if other MC-1 owners have noticed it; if not, could be just his MC-1. Am I missing something and only Balthazar uses Infuse/DV? Well, I am probably in a pretty small group of people converting 4K BD to Profile 8 MKV for DV compatibility with their AppleTV  Well Caw may be right then, and you are the only person doing Infuse/DV. |

I can't believe that there isn't a thread on this already, and apologies if there is and I missed it. That said, if this a first comment, a few starter questions for discussion.
No question about it, for $1,999 the new receiver is a reasonable deal, but reviewing the specs and features there are a few cautionary notes:
> There is no tuner. By definition a “receiver” has a tuner. Why the omission?
> OK, one might say, who needs a tuner when everything is streaming, but there is not any mention of internal streaming function. That is a miss in comparison to the mainstream brands
> No mention of connectivity for DNLA. Is it, or will it, be there so we can stream from servers?
> Only six HDMI inputs rather than the eight common at that price
> HDMI 2.0 and not HDMI 2.1? A miss as it isn’t about 8K, I agree with Dan there, but that has to do as much with HDMI 2.1 features such as ALLM and the ability to pass through VRR for
gamers and the other HDMI 2.1 features as anything else. Will there be an upgrade path? When, and at what cost?
> Same for HDCP 2.2 rather than HDCP 2.2. A possible “down the road” problem.
> EMO-Q is a good system, but any reason why there is no option for Dirac, as in the processors?
> What are the DACs? TI? AKM? ESS? Which ones, and same for all channels or different versions for the various channel pairs. Will at least the L/R DACs do DSD?
> I may have missed it, but there was no mention of an app, but I have to believe there is one. Yes?
Again, on the surface it does seem to be a reasonable deal, but the items noted above could be problematic for some while not a factor for others. One has to thing that the Emo team took all of these into consideration during the product planning process and have good reasons for doing what they did, the way they did it. An interesting comparison might be Sony’s new STR-AZ3000ES. To be fair, it’s $100 more and while it has some things that the MR1 does not have such as AirPlay2 and Spotify and similar. Yet it doesn’t have an balanced inputs and is 11.2 rather than 13.2. Look at the new Denon and Marantz models. They don’t have anyone comparable at the $2K price in terms of channels and amplifiers, but they, too have their own and pluses and minuses up against the MR1.
I guess this sort of comparison is what makes this a fun ball game. Some will gravitate towards one brand and feature direction while others will look elsewhere. An interesting product from Emo that one suspects will find many homes.

An interesting product from the Emo that one suspects will find many homes. Cirrus Logic CS42528 DACs In an earlier post, Keith mentioned the dacs. The MR1 blows away the standard fare receiver in the amp section. I would assume that Dirac was left out because of cost and the fact this receiver falls in the BasX line. Receivers traditionally have tuners, but I think you will find a majority don’t use them. This receiver may not have all the fancy bells and whistles, but it is cool. Streaming? I’ve always used an external streamer. Yeah, additional HDMI inputs are always nice. |

To be honest, one would expect a better DAC than the '528 in a product at this type. As was the case with not having Dirac, which is understood due to cost, this is probably there for the same reason. That said, at least better two-channel DACs for the L/R and then one in some fashion for the center. I'm guessing this also means no DSD?

Had the DV problem twice tonight with AppleTV+ content. Now it is becoming more annoying.

I have so many thoughts right now, but I am curious as to what you might consider to be a better DAC? The chip alone does not tell the story. And no DSD in the MR-1. |

I meant simpler things. 2 companies around the same time and for the first time in their history introduce home theater receivers to the market. Coincidentally, they have large glass panels on the front, which makes them visually similar ... And I do not doubt the advantage of our MR1 in many respects. |

Also, I had never heard of Infuse prior to this thread, would appreciate a lesson on what its purpose is and what it’s used for. Assumption is computer based video storage…anything else? The app does get good reviews. |

The app does get good reviews. The two instances last night were not in Infuse, but the AppleTV app watching AppleTV+ content in DV. Paused, came back, hit play and everything went black. Had to completely reboot the chain to get it working again. In those cases, the TV was in DV, switched out to SDR for the screensaver, and when I went to hit play it tried going back to DV content and instead went blank. It has to be the MR-1 causing the issues as this have never been a problem before. As for Infuse, I am using it as a player for my Plex server. It is far better than the native Plex app. |
