I was given a Dorado PSU and Caiman SEG DAC on loan for a while to test in my headphone rig by another member here and have a few layman impressions.

I currently use:
DAC: CA DAC Magic+
Amp: Capella
Cable: Fisual Pearl Optical
Front End: MacBook Pro (2013), Clementine, FLAC
Headphones: HD700s
Power supply: Default + Tacima CS929C/BP

Replacing the CA DAC with the Caiman was an improvement enough (I've had it in my set-up before) but powering it with the Dorado was yet another step-up.

As far as I can tell & hear it's a very simple improvement. Songs I know very well were a lot clearer, but not any brighter. There seemed to be no colouration added or removed from the way the system sounded before. There is far more clarity with voices, especially female. There was a change in the bass but I can't pin point it, most likely because I don't know the ins and outs of "bass" but I can say for certain it was a benefit, not a drawback.

All in all I will be buying one. I'm going to assume I'll hear very different results when I use it with my DAC Magic+ but I'm confident it'll be worth it.
