TJ you said it pretty well: greater transparency, soundstaging, and dynamics. I went through a similar burnin on my 5 week old Hydra and found it still needed several weeks before it settled in. The way it allows music to unravel in that uncongealed yet totally coherent way is remarkable. I live in a high RFI/EMI urban area and found it to reduce powerline noise but not completely eliminate it (I still hear some background noise up close). However, I believe that burnin for this device is critical in order for its Stardust compound to couple fully with powerline noise. While the reduction in noise has been gradual, ultimately I have come to realize that my Hydra is responsible for the quieter power and massive gains in musicality. I also noted that it works synergistically with PS cords and that my integrated amplifier suffers no ill effects when plugged in (on the contrary it sounds more dynamic). In my opinion the Hydra is even more effective than the powercords themselves and that is saying a lot.
