I can attest to the benefit of adding the DDC to the LAIV Harmony DAC. I found the LAIV DAC on its own to be decent with neutral warm but fairly detailed sound but lacking something. A little too vanilla with just average sound stage width, height and depth. There was also a kind of lack of focus. The DDC cleared that all up. It became very focused, tightened up but not restricted in any way. Actually the opposite. It opened up in all 3 directions, became richer, more lively. I am going to see if an iFi iPower2 power supply on the DDC will help even further but I’m a bit skeptical. I’m quite happy with the sound or of this setup. Using Anthem AVM60 as preamp, Moon 760A power, Wilson Sabrina X speaker, dual REL S/812 subs, Denon DCD-S1 CD player, Magnetar UDP800 for SACDs through cheap HDMI to I2S converter.
