Just got my MCRU power supply and it took the QuteHD to a whole new level. I've got mine connected to an Off Ramp too. With the new power supply the music has more weight, everything sounds fuller and more organic. The soundstage grew too. This upgrade is a no brainer. My only quibble with the MCRU power supply is that the blue light is too bright (easy fix with something to cover it) and that there is no power on/off switch. This means that the dac and the power supply are on 24/7. It's not that big of a deal and I'm not going to sweat it.
For the die hard audiophiles, they also make a power supply for the power supply! Ha, just kidding about that last part.
