Hmm don't know anything?
You can always contact me and find out. Since I have lived most of my life in the world of pro audio, I do have a different take on fidelity.
AC Line Impedance is a big problem. And I would suggest a little research in this, will lead to the understanding of why certain devices in power management should NOT be used back to back. Also, AC Line Impedance can effect an amplifiers performance, but with regard to this UPS question remember this simple fact: Manufacturers of power management, design equipment to specifications of electrical codes and safety certifications, and the proper implementation of the designs are critical. Otherwise electronic components can "burn out".
As far as power conditioning and surge protection, many people don't even understand or misinterpret the basic concepts of why it employed in the first place. As a result, they choose the wrong device for the wrong reasons or applications. Most people against the technology have never really beta tested it in multiple location world-wide, for extended period of time, to see its benefits.
Always keep in mind, its always good to be well grounded.
Have a great day!
