For anyone wanting an excellent sounding small setup, the $299 Meridian Audio Explorer2 USB DAC and the MS-3 with the latest MQA decoding firmware sounds excellent. It has both headphone and line level outputs. Used it with my iFi iCan headphone amp and HiFiMan HE500's with excellent sounding results. This DAC uses my preferred minimum phase filtering instead of linear phase filters.
Have listened to many of the 2L MQA sample tracks and they sound excellent over the system. This will also let you decode MQA from TIDAL streaming audio on the HiFi channel.
After discussions with Math Audio, Room EQ will now be a standard component added to Foobar2000 for room and speaker correction. Anyone with a MS-1, MS-2 or MS-3, I highly recommend giving this a try. It needs a calibrated mic with calibration file, so there are a few options. The easiest to me is the Dayton Audio UMM-6 USB mic since it is plug and play with Windows 7, 8.1 or 10. Cost is under $90 from Parts Express.
Here is the link for anyone interested in giving it a try.
