I bought a Monster Power HTS 1000 clean power powerstrip, and I was totally amazed at the difference it made.
I don't understand about clean or dirty power, really, but what I DO know is that it made my amplifier sound clean with zero hiss. I used to be able to hear a hiss come out of my amp when I turned it up very loud. I used to be able to switch inputs to an unsed one, and turn the volume way up, and there would be a hiss. Once I hooked up everything to the Monster HTS 1000, it remains dead silent all the way up to 0db on my Yamaha. I don't know what, or why, but it made my system sound better.
