I just replaced my P500 with the new Hydra 6 and am amazed at the sonic improvement. I was not convinced while waiting for the Hydra as I liked the theory of what the power plants do but in the listening there is no comparison. The Hydra is way better sounding. I used to listen to music and think of how to make it sound better but now I just listen to music. I'm sold and extremely excited. Check out whatever you can that's available to hear and you'll find the one that suits your tastes. In terms of the Hydra 6 or 8 compared to an Ultimate outlet there is really no comparison. The UO is good for what it does but the Hydra does way more in terms of sonic performaance. I started with a High Current UO ,moved to the P500 and finally the Hydra 6(new model)and I feel I need not look further. Perhaps there are better conditioners out there that would have me excited as well but I'm grateful to be able to enjoy the Hydra.
