Thanks for the impressions with Mjo n V200. Today, i had the good fortune of trying the XC with a Chord Hugo playing mp3s off my Android phone via bluetooth connection. By golly it sounds good!
I heard the mid bass i was missing. The sound was clear, airy and transparent. Bass was pushed upfront and overall the music sounded fuller (rather than thin n flat as i heard it with Modi/Lyr). I now believe the Dac can make a noticeable difference. The headamp is pretty impressive for a portable and drives the XC well. Of course, i expect it to improve further with a dedicated amp. Take note this is just with lossy files over bluetooth. Now i need to decide if this is the upgrade that will bring my set up a clear notch higher. And plan a budget to include a separate amp as well..Lyr 2?
