Benefits of power conditioning


I'm just starting to build my first stereo and I was wondering about the benefits of power conditioning, should I use one of these devices? What improvements would one hear?

My system so far consists of:
Speakers: Axiom M3ti
Amp: Blue Circle CS Integrated
Cables: Straightwire Stage (spade terminations)
Stands: Energy CST-M 24", (filled with sand)

Thanks in advance,

I'm using the Powervar ABC 700 11 for home theater stuff. And a Oneac CP 1107 for my preamp and dac. My amp I plug into the wall. Paid 45.00 including shipping for each of these. The Powervar is a 7amp output and the Oneac is 6.3 amp output. Plenty of headroom for what they're used for. An added benefit also is they will quiet the picture on your tv. I live near an industrial area and originally wanted them for power problems I've been having. The sound is better now with the power conditioners in line (like listening late at night all the time). Ebay is your best bet for these. I'm afraid I seriously doubt the audiophile conditioners are any better. These things were designed for labs and hospitals and are therefore not as cosmetically pleasing as the specialty models by Monster and the like.
Warnerwh,
Thanks for the advice. I'll check them out. I guess that at the very least it will sevrve as a surge protector.
I went to one of my local dealers to check out some options for power conditioning. The dealer said that my system was not 'revealing' enough to benefit from PC. That comment is at odds with most of the posts here in A'gon. He said that the only PC he has heard that makes a difference is one of the high end PS Audio models.
Your dealer is incorrect. If you want to check out some very affordable conditioning, order a Quantum Electroclear for $40. It is a serious bang for the buck and and can be used with either you digital front end or integrated and can also be used in conjunction with much more expensive line conditioning very effectively (I use two in my system along with more expensive conditioning). The electroclears are VERY effective. Your first step, though, if you have not already taken it, is a high quality receptacle. I'd probably do power cords next and line conditioning after that.
