Power Conditioners: Myth, Magic, or Necessary


I own a Granite 860.1 monoblock system which I love.I upgraded the power cords to premium $395.00 models.
I can hear no difference. I bought these upgraded PC's
because I thought I was "supposed to" after reading all the ads and testimonials.

The next logical upgrade for me is a power conditioner.Do these power conditioners actually improve the sound of my system? Or, are they like the "Emperor's New Clothes?" By that, I mean a hype.Are they a tweak for audiophiles obcesssed with perfection?
I am referring to power conditioners in the $500.00 to $1000.00 price range.I live in Riverside, Southern California where the electrical power is as pure and clean as the skies.

In my opinion, there is little doubt that the needs for power scrubbing is related to the power source in your area. It does vary from one area of the country to another. Urban areas are worst. If you live in a rural area and have few "dirty" users in your area, it is concievable that you may realize little or no improvement. Also, things depend on what you have in your house that may interject noise onto the line. If you have few, or no offending items, this would also lead to not hearing a difference.

While I generally maintain that differences in sound can be heard by most people, if an upgrade in power cord makes no difference to your ears, then IMO it is not a cost effective modification for you.
If I were you I would sell those power cords and enjoy the music, why upgrade if there is potentially no gain? Why do you feel you NEED power cords and possibly a power conditioner? is there something you don't enjoy about your sytem? Let me just say I am an avid PC fan but simply put if you can't discern the difference don't spend the money-it doesn't mean your less of an audiophile.
i have old power wedges and dedicated circuits - the improvement i have most noted is they help in the elimination of a static low level hum heard mostly when there is no music playing. i still have to float grounds and they do not not effect transformer hum. all in all a small gain for me.
