Power Conditioner Helpful?

I would either get a Shunyata Hydra 8 power conditioner or a PS Audio Power Plant which is actually a power regenerator. The rest of the units out there to me are not worth their price.

Yes, I think your system would benefit with some type or types of power conditioning. There are so many products on the market that I don't know what to suggest. Try a search on Audiogon or AA for ideas and /or reports regarding how well they work.
You also might take a look at my system posted on Audiogon for some ideas and different products that are available.
Psychicanimal might be able to suggest some good alternatives for you; he's very knowledgeable along these lines.

Try one that you can re-sell for near what you paid.

I strongly and respectfully disagree with Timo. I'm not a fan of the PS Audio's electric regenerators, but I do love the Shunyata Hydra and the Audio Magic line, even more. The Sound Application line is also wonderful. Watch the 'gon and see if you can pick up a used Mini Stealth. Once you hook that baby up you will be released. I have gone from their Stealth, to the Matrix, and now, the Eclipse. A world class power conditioner with matching power cords = electric nirvana. A significant component of any audio system. peace, warren
