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)

At first attempt the M-100 headphone-out circuit seems wimpy driving Sennheiser HD650's.  Must  pump volume all the way up to level 60 before it reaches dB levels I consider 'loud', and even then the HD650 characteristic 'dark veil' is present in the sound (indicating an under-powered source). By contrast my Creek 5350se drives the HD650's effortlessly and with buckets of dB's, lucidity, articulation, deep- and hi, blah blah quack quack, etc.

Maybe this is just the way M-100 is config'd from factory (ie really have to jack it with hi-impedance 'phones like the 300ohm HD650's)? 

Or, the M-100 headphone-out is really anemic.  I didn't find any specs for it in the docs (output impedance, power,  etc).

I have to turn mine higher on headphones (AKG 701)  but not up to 60 usually around 40. Where  do you have binaural set ? I set binaural on medium.

djones51: I don't have the binaural add-on option.

The AKG K701 has a low impedance of 62ohm so they are easier to drive.

I played around for a bit with my Sennheiser/Massdrop HD6xx both with and without binaural.  For me loud is about 50 and I didn’t try to go up to 60.  So far I think the circuit sounds a little dark and not too detailed, but I want to spend some more time with it.  This is compared to my desktop Teac 501.  The binaural light sounds pretty good but the medium and strong sound too processed.  It would be nice to be able to add a little eq.
