So I've calibrated Dirac and like what it does. Since I listen mainly solo, I did the one seat deal. Too bad you couldn't store a multi-seat profile for when you have company but I'm not going to worry too much about that.
I am having a problem, though. At the beginning and end of each song there is a very slight thump or noise, as if the muting between tracks isn't quite working properly. This happens with my SONOS Connect via coax and Roon on a Mac mini via optical. Any ideas as to what's going on? This is a brand new XMC-1 running the latest firmware.

Does this only happen with Dirac engaged or can you hear it on Preset 1 or 2 as well?
What are the track types; FLAC, MP3 etc. and what sample and bit rates.
Is it between every track or only where the sample and/or bit rates are different between them?
Are the SONOS and Roon playing gapless?

I source my XMC with a Sonos, and I don't have any issue like you describe. Perhaps there is an issue with how you ripped the music.
Does it happen with sources like Tidal via the Sonos?

The songs are on any album that is playing sequentially. I can hear it with Preset 1 and Dirac using stereo and PL2 but not using direct. I do not hear it with my Yamaha RX-Z7 which I reconnected to check. |

Mark It happens with Tidal and Apple Music on the SONOS. I've gor 1800 albums I ripped using iTunes. The sound is very low in level but there. |

Quite odd. When you say the sound is very low level, can you hear it from your seated position or do you have to put an ear to the speaker? I have never gone up close to the speaker, but I hear nothing from my seated position.

I went up to the speaker to make sure it wasn't something else in the room, and obviously it's much louder the closer you get to the speaker. |

Some more info. Listening to SACD via an Oppo 103 in either DSD or PCM mode does not exhibit the noise.
Which makes me think it's an issue with how the XMC is applying processing to get to the various listening modes that aren't direct.

Well, according to a post I read over at AVS this is a an issue that Emotiva is aware of but don't as yet ave a fix.

I did a little more testing, and it is definitely related to the muting circuit. It is louder with Dirac but is also present on the presets. If I go close to the speaker, you can hear a hiccup just as one track ends and mutes and another when the next track un-mutes. Very annoying as 80% of my usage is music. And it occurs via Coax, Optical and HDMI (playing music files via a hard drive attached to the Oppo 103).

And it occurs via Coax, Optical and HDMI (playing music files via a hard drive attached to the Oppo 103). Yes, the UMC-1 does mute when the signal drops below a (very) low level. Interestingly, even though the mute operates for both digital and analog signals, the mute circuitry itself is purely analog, but it is controlled by the processor in both cases. The processor "listens" to the signal, even when you are in direct mode and the signal you hear doesn't go through the processor on its way to you, and mutes the output when it determines that the signal has ceased - to cut off any "dead track" noise. Instances where there is legitimate music this close to the noise floor are few and far between. (The UMC-1 is, primarily, a surround sound processor, and in movies instances where you would want to clean up a slightly high noise floor exceed those where there is very low-level music playing.) Since you asked: 1) This function is rather buried in the UMC-1 firmware, so it is quite unlikely that it will be eliminated (or made adjustable) for the UMC-1. 2) The XMC-1 does NOT do it. Well, the XMC-1 may not "mute" at a low threshold level, but it sure does mute at every pause in the audio. Which causes it to re initiate the data stream handshake which causes a mute delay until it's done. And I mean every pause. On YouTube if someone is speaking, it will cut off the beginning of the next word every time the speaker pauses. And I don't mean occasionally. I mean every other word. I'm going to have to run an analog line from my computer's speaker output to an analog in, just so I can listen to lectures. The beginning of a track delay is very common among hi-end processors. And the XMC-1 has one of the shortest delays of the genre. On the other hand, google the word "genre" and try to have the computer play the audio pronunciation for you through a digital input of the XMC-1. It's quite embarrassing. |

Well, according to a post I read over at AVS this is a an issue that Emotiva is aware of but don't as yet ave a fix. If it is the same problem, Emotiva say they can't fix it as it is something buried in the DSP which they can't get at. I get it on DVD/Blu-ray between logos and menus and from the TV when there's a switch between studio and outside broadcast on the news, for example. It is very audible when using the Dirac preset and almost non-existent when using Preset 1 or 2. I don't hear it between Squeezebox tracks on coax. I suspect that's because the SB is playing gapless. You could call Emotiva and explain the problem. Another voice to add to the report can't do any harm. EDIT: Keith's post above refers to the UMC-1, not the XMC-1. The XMC-1 does have a problem in some people's systems with clicks and pops as I described above and Emotiva's answer has always been the same; there's nothing they can do. |

FWIW - This is NOT exclusively an Emotiva problem. I've had the same issue with multiple brands of AV gear over the years. Either the muting cuts off the first half-second (or more) of each streamed song or there's a noise when the transition from "muted" to "playing" occurs. This is a lasting and persistent issue causing my general animosity toward HT gear. Now to be fair, some of the latest stuff I've listened to doesn't have the issue, but in general, it's been there on about 50% of the HT gear I've heard.

Boomzilla My Yamaha RX-Z7, which the XMC replaced, and I've enjoyed for five years does not have this issue. I guess I'm going to keep it and move on to the DDRC-88A. Although it adds an additional DA/AD conversion into the loop, I've been told it doesn't mess with the digital stream. |

Yamahas, in my experience, have never had the problem. I've had it with an older Onkyo, and a Harmon Kardon if I remember right.

This is click/pop issue that many suffer from. Other brands do have this issue and have found ways to implement fixes..
Anthem had the same issue on the x00 series and have fixed it on the x10 series. Sorry to the op for your bad luck.. I feel your pain sir.

What sound mode are you using when listening to music files? I typically listen with DIRAC on, but I have also listened to it without Dirac. And, I have listened in two channel and multichannel and about every processing mode there is...never heard any sounds between tracks. How do you listen? Mark |
