Micromega M-100/150 field reports


Got a M-100 or M-150?  Share your setups, tweaks and observations, and help out your homies.

My initial M-100 config and some early observations in this thread.

Things I'm wondering about:

  • hacks & upgrades to LAN infrastructure including h/w, and whether they make an objective difference in reproduction from the M-100/150
  • power cords/supplies, with same question (objective difference?)
  • MARS room correction performance & value
  • whether Micromega will have any relief for the abject instability of their Android control app (circa 2016)

I received my M100 last week.  So far, so great.  It is replacing a VAC Avatar Super, so going from pure tubes to pretty much pure digital.  The amp and streamer are outstanding with really good imaging and presence.  I run a Thorens TD125 Mk II (Vinyl Nirvana modded with SME M2-9 tonearm and Ortofon 2M Black) into the phono.  I can say the phono stage on the VAC was better, but the Micromega is very good.  I’m going to try feeding a Parks Audio Puffin to see if I can warm it up a bit.  
I have the MARS and really like it.  The difference on and off is not subtle and plan to leave it on auto (on).  Other items are a Purepower 1050 power regenerator and the power to the M100 is via an Audience Powerchord. I haven’t compared to stock.  
A couple other things, my Ethernet comes in from a Plume pod situated nearby (mesh Wi-Fi).  And the iOS app is in pretty good shape.  Also, so far I’m liking Roon for feeding it but Apple Airplay works pretty well too.  JRiver is just too terrible an interface for me to want to use it.  

"The amp and streamer are outstanding with really good imaging and presence."
benb: that's my experience too with the M-100, and it just keeps getting better the more material I listen to (varying genres, recordings, volume levels etc). No MARS, no power conditioning and a Cullen Cable Crossover Series as power cable. Other than Audioquest Sydney rca from CDP (which I don't use much), no other fancy-pants interconnects to speak of. For my money those aren't a good & credible investment.

Like you I'm getting super-good imaging & stage, presence and drive. Totally stoked.

I did have a weird encounter during .flac playback via http over ethernet through the M-100 LAN input. I use the BubbleUPnP for DLNA/Chromecast android app as control point, with the M-100 as UPnP renderer via its LAN input. Btw the BubbleUPnP app is excellent: well-designed, feature-wealthy, responsibly and frequently maintained, rock-solid stable. Superb value, from the Google Play Store.

I use the Micromega android app to control the M-100 hardware: volume, input sources, etc. Sadly, that app is of entirely different caliber than BubbleUPnP (see my earlier posts about that).  No response from Micromega to my questions about that. 

I had just played back a single track from .flac, and selected another single track in BubbleUPnP.   I hit Play - and nothing happened. Tried again: nothing. Rebooted the BubbleUPnP app - and it no longer found the M-100 as a UPnP renderer on the LAN. Rescanned for devices in the Micromega app, and it too no longer found the M-100. Restarted both Micromega app and M-100: still no UPnP renderer.  M-100 still had a valid IP, an active network connection and responded to ping. All other M-100 functions and source inputs still worked fine, as did the remote.

The tl;dr: after hours of troubleshooting including router and network debugging, and hw/sw isolation, I finally pulled the nuclear option and reapplied the firmware update to the M-100 network module. That fixed it: M-100 reappeared as UPnP renderer and playback via its LAN input works again.

A cautionary tale but hopefully useful outcome if other owners have the same problem (I didn't find any out on the interwebz). I think it's highly unlikely the BubbleUPnP control app 'exploded' the UPnP interface on the M-100 network module - for now I'm treating it as an isolated "lost-its-mind" failure on Micromega's part.



Mine gets lost in internet space all the time. The android app can't even find it now, jriver loses it all the time I don't bother with it anymore I just use my cdp. I can ping it, I can get to it typing in it's ip address. I did all the recent updates. The MARS works bery well.
