You may ask why you would need to condition your power. Reasons include:

• AC power being contaminated with noise. Additional noise is added by your everyday appliances degrading the performance of your sensitive audio / video components.
• daily electrical surges and spikes putting your equipment at risk.
  
   

In a nutshell a good power conditioner:

• filters and cleans incoming AC power and dramatically improves your equipment's performance. Audio sounds better and your picture looks cleaner.
• increases the longevity of your connected components since contaminated AC add wear and tear to power supplies and other internal circuits.
• protects your equipment from damaging AC events such as surges, spikes, lightning and high voltage.
