I have also received my Metrum Mk2.
I am really liking it. I am using Foobar2000 with Wasapi Event.
The sound is very organic, extremely musical It lacks a bit of treble definition, and actually pushes me to listen at higher volumes. The dac is the best pairing I have ever heard with the Audio Technica AD2000. The Metrum has this slightly midbassy/lower midrangey, sirupy sound, and it melts perfectly with AD2000, while other sources like the Eximus DP1 made the AD2k sound too hot in the upper midrange. The deep bass is good on the Metrum, quite impactful albeit a bit short from that of dac's like Museatex (Idat-44, Bitstream), the Eximus and few others.
Treble presence seems to be a bit subdued; slightly smoothered, but it also seems to improve / get slightly drier when setting Wasapi at 24 or 32 bit.
Anyway, these are only very first impressions because I have to do the following tweaks to my system:
- get a different amp than my Headamp AE-2 for the AD2000 (since, albeit being quite amazing with AD2000, it's not enough to provide them the best separation they are capalbe to offer)
- use my USB cable (Forza audioworks twin cable, with separate inputs for usb signal and power) with a battery instead of using two different usb ports on the pc...... I suspect that using separate battery power will make the Metrum digital input every bit as good as that of the Hex (which takes power differently from the Octave, and not from usb)
- listen to it with my Audiocats-modded Babystax
- wait for some components to arrive for modding my StaxSRM-727A to be ready for working with normal bias Lambda and use such system
So far, I think the dac is absolutely good value and very, very easy to listen to.
More specifically, Octave Mk2 + Headamp AE-2 (and even better a dynalo or Gilmore Lite, based on several users' comments) + Audio Technica AD2000 makes for a killer setup for the price, albeit a bit too saturated.
