For what it's worth I sell monster and panamax. I prefer panamax. I don't for a moment disagree with gentleman saying not all or even most will see the difference though. My friends and I did tests on a pioneer elite w/ matching Bluray on dark shots in transformers we noticed less noise on the screen as we isolated the TV to it's own circuit. My issue has always been product life span. It is the power transformers job to condition the power. It is also the power transformer or circuit boards attached to it that fail most often in electronics.Less work for the power transformer = longer product lifespan.
Does power conditioning really matter?
I have a friend who is setting up a budget system with a nice hi def plasma (Pioneer PDP-5020FD) and an entry level receiver (either Denon AVR 1909 or Onkyo TX-SR606) who is wondering whether the Monster conditioner for $300 that the salesperson is pushing is really necessary over a plain surge suppressor. Will this make a difference in his system?
