I went the other route. I generate my own power. I use battery power supply whenever possible. My turntable and power amp are supplied by battery. I am working on converting my preamp to battery power supply. My MC step-up is a passive transformer and doesn't require power. If you want clean power, this is the cleanest of clean. Sonics are greatly improved with battery power. I use my solar power generation to keep the batteries charged between use. For the remaining AC powered items(CD player and TV), I use a Studer Perfect Sine Wave power inverter. No noise. Oh, and by the way, I spent no more than many people who have shelled out big bucks for fancy power conditioners and high end power cables. I also like the added benefit of not having a power bill to pay every month. And I never have a power failure or a lightning strike come in through the power lines. Not bad. I like it.
How to fight dirty power - I need your help
My system is AMC CD8B-Zucable Oxyfuel-CREEK-OHM12-Zucable Disco-Odyssey Stratos-Groneberg Quattro Reference-Migrage OM-10. My amp is directly plugged into a FIM outlet in the wall. The other component went through a Monster HTS2000. The voltage in my house is relatively high, usually in the range of 126-130V. The sound from my system is sometimes very good, but sometimes, especially in the evening, is tasteless. I believe the main reason is dirty power and high voltage. I’m trying to figure out an inexpensive way to fight the power problems. I don’t want to spend $1000-2000 to buy a power regulator. I’m thinking variac, but heard different opinions. I guess the result to some degree is system dependent. Now I need to figure out what is the key component that lowered sound quality when voltage is high or the power supply is dirty-CD player? Amp? What is the best way to solve the problem?
