It kills with my HD212. I do have an HT322, as well. I'll try and pair it up with the MM.

Back panel of mine
First impressions are good. Haven't got to play it with a band yet but I believe it work well. The things that drew me to this amp: high power, low price, eq. It delivers on all 3. The other bells and whistles I can live without. Particularly the high pitch whistle that comes with the colors. As it sits it starts pulsing from high pitch to higher pitch and back with the color changes. I find the red and blue to be least offensive and have it set to stay on blue right now.
The fan noise is somewhere between quiet amp fans (mesa subway, thunderfunk, genz) and loud ones (pf500, kxb500). About the same as the prodigy. Certainly not noticeable while playing and tolerable when not. But that high pitch with the lights...I know some people don't care but I can walk into a room and tell when the tv's been left on but the cable box turned off because I can hear the high pitch. It annoys me but not others.
So I'm not sure if I can deal with it or not. Going to give it a week or two. I tried to live with the kustom but couldn't.
But the sound is great. And it's going to cost $25/month for the next 19 months so it's probably a keeper. Overall I prefer the simplicity/features/quality of the subway but this is an inexpensive backup option with a different flavor.
For fan noise reference, here's the subway on top of the mm. The subway is actually blocking some of the peavey noise:
And here's the high pitch pulse:
Now, I know this kind of thing is not a big deal to some and the fact that I'm pointing it out could make some people go into defensive freakout mode (it's happened before). Please understand it's just one point about this amp that I think bears mentioning. It may or may not be important to you and I will love and respect you in the morning regardless.
Just curious, what aspects of the subway do you feel like demonstrate higher quality?
The lower fan noise, the absence of the high pitch and the 5 year transferable warranty.
This is really hard to argue with.
Anyone know if this is present at all the outputs? Preamp send, DI, headphone, and speaker outs?
Not sure about outputs, but there is a fix for this, so it isnt something that users have to live with.
I thought the fix was for a noisy AUX in?
Or are you suggesting the "fix" is disabling the lights?
No. The issue is all related, @BbbyBld has said that once you fix one, the high pitch goes away.
I haven't tried all the outputs but I don't think it's in any of them. It's just an ambient noise the amp makes when it's on, not thru the speaker.
Help me out, please. The only thing I saw was this:
That'd be cool. It's the only negative I see at this point. I'm not attracted to the comp, crunch, kosmos, flashy thingys...
If they'd dumb this thing down to just a 1k amp and eq without the gizmos and light show it would still be a bargain but I imagine it would bring down the size and cost and I'd be like "HOLY $%^&, Batman!"
That's just me. Where others see cool, high tech features I see something else that breaks and needs fixing.

Hopefully this will clear some things up...
Some of the first production mM amps had a high pitched whine that would be audible through the speaker output. I updated the aux in circuit to stop that. This had to do with the grounding of the aux in jack. It's common practice to add optional ground configuration components during development when you have a product with multiple circuit boards with multiple grounding points in order to minimize noise. The update I'm talking about was basically to reconfigure one of the optional ground routing components so that all mM units would not have this noise. This was never an issue early on, but sometimes these minor issues pop up when you start manufacturing hundreds of something. Anyway, that issue is no more.
Some people can hear a high pitched whine coming from inside the amp itself when its idling or running very low signal levels. All mM amps do it and it's pretty subtle. Some people notice it more than others. That has to do with the power supply regulation. The reason why the sound of it can change with different backlight colors is because different colors present different loading conditions to the power supply that the regulation has to deal with.
Many people have commented about the "slam" from the amp module. The secret sauce is mainly in the switching power supply and the regulation. The switching power supply in the mM is very powerful, more so than what's typical in commodity amp modules, and it really wants to stretch its legs and run wide open. The whining noise comes from it throttling itself back. The ability to throttle back is very important because it allows the module to be compact and efficient while still having ample power in reserve. This is not an issue with some other amp modules because they simply don't regulate the rail voltage for the power amplifier so that the SMPS can push back against the load--there is no power in reserve, and I would say the consequence of that is wimpy sound.

I can't remember if this has already been answered.
If one were looking at buying a used mM1000, is there any way to tell if it is one that has the update for the Aux In grounding?
If I were buying a used one, I definitely would want to make sure it already had the update. Seeing as how the warranty is non-transferable and all....

I could be wrong, but I believe that placing the Subway on top of the mM would actually increase the fan noise heard, not block it. Either way, playing live or in a studio,which I've done a lot with this head, I don't find the fan to be loud. Perhaps I'm too busy enjoying the awesome sound that it delivers
YMMV But it's a definite keeper in my book.
Yes, by the serial number.
If the serial number prefix is 0DBFI and the last three digits are lower than 100, it COULD have that issue. Some of those units were updated before being sold, and some were returned by customers and were updated in the factory repair center, but if you want to be sure, just avoid those on the used market. However, I've seen one listed in the TB classifieds where the seller showed documentation that his amp was updated.
From what I can tell, mM's built in 2016 (so far) have a serial prefix 0DBFM.
Hmmm? Maybe I just need to listen a lot closer but I just don't hear that hi-pitched whine in my MM yet. I've put my face/ears right up to it and nothing to me. While the amp is on mute or not, just not hearing that particular noise. Not trying to be a super, Peavey, non-hearing, fanboy for this amp; just not hearing that one noise in my amp.
I mentioned the loud fan earlier here. At the gigs this past weekend, that fan noise I heard each time I started the amp up still seems loud to me. But this became a non-issue just with the typical room noise at the clubs while setting up and definitely was not too loud while playing the gig.
The fan in my GK MB800 is about as loud and this fan; in my GB 12.2 that fan seems very quiet to me. Then again, besides being very aware at home practice, the fans in any of my amps haven't been a issue so far at gigs. Haven't needed an amp to record in the studio for a couple years so not an issue for me. But I could see how that might be for others who might use it that way.
Another thing I think Bobby already cleared up. MY OM, yes I actually RTFM for all my new gear, states not to run the amp without a load. I think most here are all clear that is incorrect. But just in case some are perusing the OM online and come across this. Anyone correct me if I am wrong here. Peace y'all, e.
*I was typing as Bobby posted his reply above so missed that. I'll check my amps' serial # soon. I purchased this amp last week, so could be a newer build.
