Hi-Fi Power Conditioner ?

I recommend a PS Audio Power Plant Premier for your digital end and a Shunyata Research Hydra 6 or Hydra 8 for your amps. If you can't swing a Power Plant for the digital end I recommend a PS Audio Quintessence (on sale right now on AudioAdvisor). It's what I use and the noise floor has dropped away dramatically. Super quiet.

BPT would be a good choice, if you can find one used. They do a lot of things well and for the money are tough to beat. They are also very well built.

I agree with Macdadtexas. I also own an APC S15 power conditioner and it is the best purchase I have made in many months. You don't want a blackout damaging something in your system. And the sound is good too! Priceless is not an exaggeration.

A third for the APC units. I have had the S10 since the month it was introduced on the market, and it both protects my equipment and manages not to do anything audibly negative to the sound of my system. Until last year the unit protected not only my stereo but all my home theater components as well.

I once read a review of the APC "S" series that mocked other power conditioners whose owner's manuals intructed the user to unplug the power conditioner during storms. That was quite hilarious - due to both the jab and the fact that someone would make a power conditioner that wasn't safe during a storm.

At any rate, the APC unit is fantastic, and with it you can rest assured your equipment is about as protected as it can be from nasties coming over the power lines.

Furutech e-TP80 AC Power Filter. Great filtering, no protection. Priced right(less than $600?). I have used used 3 of them, in two systems, for years.
