AC / DC - What are you using? Dissapointed by ....

I think power conditioning comes down to a matter of personal preference, and how a particular unit performs in a given home.

In other words, there's no perfect unit for everyone, and the same unit used in two different systems may meet with opposing points of view from the listeners.

In my system, I have always preferred passive conditioners to active/balanced conditioners.

I used Shunyata Hydra 2 conditioners for several years, and recently changed to Alan Maher Designs Reference Power Center V2. The sound is essentially the same, but the AMD unit cost me less.

None.Most cure one problem at the expense of something else.I feel a properly designed and executed powercord can and does make an improvement over the "stock" Belden.Same probably goes for cabling.

Furman. No sonic signature thst I can hear.

I also use the Alan Maher Designs Reference Power Center V2 along with a number of his Power Enhancers. They replaced a Running Springs Haley which I also hold in high regard.

Having tried power regenerators like PS Audio and Exact Power, as well as isolation transformers, I can say passive filtering suits me more.

How clean is your power? Have you ever looked at your power on an oscilloscope?

When I was in the city, my power was crap, and a power conditioner made a huge positive difference. Now that I live in the shrubs, my power is pretty clean and reliable (other than the occasional blackout when a tree takes down a wire). I'm happiest with only passive conditioning on the source components these days.

Scoping the power also helped me find where I was getting appliance noise on the powerline, and led to installation of a dedicated line, which helps immensely.

Occasionally I dream about getting off the grid entirely, with a Sutherland phono stage, Dodd preamp, and Red Wine Audio amp -- all battery operated! Anyone doing this?
