I am curious about line conditioners.

Basically the power conditioner will "clean up your power". It will filter out the AC noise (such as RF & EMI)picked up by the giant antenna (all wire ran from the power station to your equipment) that exist in your powerline, thus your equipment gets cleaner power to work with. The end result is a lower noise floor, more of the original signal from you source to show through on your display (speakers, TV's etc.). As far as the digital outlets, what it'll do is separate the digital power from the analog power. Digital sources will emit its own digital noise back out so if the analog is plugged into the same bank as the digital, you just kind of defeated the purpose of cleaning up your power. A good power conditioner will have those problems taken care of in its design just as the digital source will as well. Just be careful, some power conditioners/surge protecters will limit your amplifier's ability to draw power at an instant notice. I hope I have clearified it a little bit for you.

Try a P.S. Audio Power Plant. It will amaze you. Besides you can get a 30 day in home trial and all you have to do is pay shipping. It is with out a doubt the best I have come across. I have used Chang,Monster and Audioprism. Check out the reviews and it was also componet of the year in "Stereophile".Good Luck!

The PS Audio stuff is very nice. Just be sure you want to afford the 500 watts of power it uses (the smallest model). I assume the bigger ones draw even more power.

Ref your comment about the "500 watts of power it uses"....while it's true the PS300 and similar units are only about 50% efficient, the amount it draws depends on what you plug into it! If you are only using it to power a digital front end for example (like I do), the components only draw about 40-50W, so the draw from the wall is roughly twice that, or 100W. People who are concerned about the electric bill should do their listening in the dark!
