I am MCH like you dudes.
I run 3 dacs through an I2S bridge from a PinkFaun streamer. That's 3 Matrix X Sabre Pros. EQ'd and DSP'd in JRiver.
On the output side I have the Benchmark and 3 NC400s.
The XMC-1 is in the middle. Only used as a switch and volume control...analog MCH inputs to the balanced outs.
But I do employ the HT function of the XMC through HDMI from Directv/Oppo.
I don't use Dirac as I never liked the bass management function, but I am proficient with REW and have produced a strong house curve.
Unfortunately, my room is a bit noisier than above, best I can get is high 30s.

So is the consensus that the XMC is the best I can do given the above?

And yes, MCH is just better. If you don't believe it, ask Floyd Toole as quoted above.

In most home audio systems, acoustic space is far from ideal.
Thats why multichannel system with room corretion sounds better than measurements.

True, though we tend to live with it (or fix it, in my case).

This does not make sense to me; could you please explain what you mean?

There is a growing number of us who prefer listening to multichannel music, and upmixed stereo to multichannel music.
In fact, I almost never listen to “2 channels only” reproduction anymore.

I would never consider buying audio equipment with 2 channels only.
So when you say upmixed I am presuming you mean stereo content that is upmixed in Jriver or something into a multi channel set up? My question is if we are listening to tracks that have been mixed in stereo(old music) for multi-channel would it be as good as you say multi-channel can be?

Upmixed in auro3d or Dolby Surround.

I find upmixed stereo tracks much more enjoyable, than listening in native stereo mode.

All these crappy reviews have me very disappointed in Emotiva. I have two of their XSP-1 analog preamps. The line stage in the XSP-1 is excellent, but the headphone amplifier is useless (no power whatsoever) and the phono stage is poor IMO. One of the two units died and needed a new PS cap after 1 year. I'm done with Emo.

@DonH56 and @RichB both use the XMC-1. Either of you run into the muting issue while using your XMC1?
I have my XMC-1 for a little more than five years and have never noticed said “issue”. So not a problem in real use, or I didn’t know what to listen for??? But would feel better if the “linearity” measured better. :)

Not for you, fortunately, but for many others... I did not (or rarely) have problems in normal operation, mainly when switching inputs or starting a CD or movies, but some recordings would mute between tracks and miss the opening of the next track.

Thank you. :D I think most of this site's reviews should have a disclaimer that says "though we would like things at -110 db for provable transparency almost all the gear measured spec to inaudible at way way higher distortion levels. Good luck hearing the difference between -70 db and a -120 db distortion in a dac in regular use."Otherwise we have people dragging manufacturers names through the mud when in reality these measurements don't actually matter.
You‘re missing the big picture Gar. If a host of inexpensive DACs can measure “perfectly“ than the big ($$$) boys should be able to do the same. And Amir usually points out when something is inaudible “anyway”.

Well Amir tends to like his inaudible at "the sound of butterfly wings flapping". I'm talking more uh, down to earth :D FWIW, the XMC-1 has powerful room correction features with cheaper DACs lack. So have to take the features in to account. Personally though I've never cared for room correction including their implementation of DIRAC, but perhaps I haven't heard it done right.

@Lonnie Welcome to the forum.

If I've captured the gist of your first post correctly, it seems that you feel that subjecting AVRs to instrumented testing is unfair due to the unique way they operate. Setting aside the excellent point made by @amirm about pass through and pure direct modes of operation, may I offer the following?

If AVR manufacturers wish to be exempt from independent scrutiny on whether they meet hifi standards, perhaps they should stop advertising their units as high fidelity, SOTA, high performance, transparent, etc. Furthermore, they should post clear and complete specifications, using standards established by relevant authorities (such as AES, FTC) so that consumers can make informed decisions about where products lie in the grand scheme of things.
If I’ve captured the gist of Lonnie‘s post correctly he’s saying it’s unfair to compare the test results DACs vs. AVRs. NOT that testing AVRs or prepros is unfair.

Now let's see the graphic showing where each of the AVRs sit relative to the amps and DACs tested by Amir...

Yeah, neither you nor an industry rep want to see that one!

But I am glad you're happy. It's important to be happy in life.
But it seems, by your bias (to anything?) you are not a happy person.

Play an opera with many tracks but no silence between tracks. It will mute for a second between tracks. Unlistenable. I have an NAD 777 with Dirac and it exhibits no such behavior. I just heard from customer service and the problem has still not been fixed.

Thanks for elaborating but while I’m a big classical music fan I do not listen to opera. So for me in my real world use the XMC-1 works flawlessly. But I see now that that is not the case for everyone.

Thanks for your suggestion Tony. I'll listen carefully to see if I can detect the issue. Best chance of doing so of what I own would be:

No. 1 MTT and the San Francisco
No. 2 Kaplan and the London
No. 4 Reiner and the Chicago
No. 6 Gergiev and the London
No. 8 Solti and the Chicago

???? Thanks.

You won’t need to listen carefully. The effect is very jarring. But, if each movement is a separate track, you won’t notice anything. The issue is when there are multiple tracks within a movement.
