I've compared both a Hydra 2 and a high current UO in my system. I tried them both on my amp, pre-amp and CD player seperately and then in combination. Power cords on all components were VH Audio Flavor 4 Golds. I ended up liking the Hydra 2 on my pre-amp and CD player best. My amp remains plugged straight into a dedicated 20A circuit with no filtering.
With the Hydra 2 on my pre-amp and CD player the music has more bloom and body, almost like tubes, yet remains crystal clear and with quiet backgrounds. Imaging also improved as did the mid-range drive.
The PS Audio UO helped with a lower noise floor but sounded almost sterile in comparison.
