The real question is how much high frequency noise you have riding into your components through your power lines. You probably won't know for sure just how good or bad your power is until you try a high quality conditioner and listen for the effects.
In my case, I always had a treble frequency response spike in my system that I had attributed to an inherent in-room design problem with my speakers (Revel Salons). This explanation seemed logical to me at the time because the frequency response spike had been a measureable "problem" in my system for years despite many upgrades of my electronic components. I also have a friend who is running the very same speakers and who has had a nearly identical treble frequency response hump that has been present in his system for years despite various front end component changes.
However, I recently learned that I was being horribly unfair to the Revel Salons and that they are not at all to blame for my treble frequency response problem. It turns out that the problem was in my power lines. When I installed the isolation transformer in my system in January, the effect on the sound of my system was astounding. My treble frequency response suddenly reverted to perfectly flat. Subjectively, the bright edge to the sound of massed violins, for example, was completely "cured."
This was proof to me that the effect of power conditioners can be not only audible but measurable as well. Indidentally, I had previously been running devoted PS Audio High Current Ultimate Outlets on all of my components. While they made some subtle improvements to the sound of my sytem, they seemed to do nothing to eliminate the high frequency noise. I have since removed the Ultimate Outlets from my system.
Needless to say the quality and effectiveness of your power conditioner are very important.
Good luck!
