Built a house in a new area and are having some problems with power. Both my Barco 1208/2 and my Mitsubishi CRT RPTV have electrical noise in the picture (NOT video noise) noticable from the seating positions. This electrical noise can be seen with very clean sources like computers and component splash screens. In the theater, the plug for the components and the plug in the ceiling for PJ are on the same circuit and are the only things on that circuit per my spec.
Had the electrician out to check the ground connections and he found no issues. He says he has been to most of the houses on my side of the street and the houses immediately behind us for power problems such as subwoofer hum (which I also have) and appliance brown outs, etc. He even talked to the electric company about it and they claim that it will be better when the whole neighborhood gets build out.
So, other that waiting, it seems like I have the option of power conditioning. I've always viewed power conditioners as snake oil, but have not really tried isolating transformers or power regeneration. Wanted to see if anyone has experience with this and if it helped. As I understand, I've got three options:
1) Power Conditioning - just regulates the voltage and supposedly cleans up the power, though no objective test I've seen measured any difference in the power. These range for $100 or so for commercial ones to over $1000 for HT ones with switched and unswitched outlets.
2) Isolating Transformers - will balance the power and regulate the voltage. These run about $700+.
3) Power Regeneration - converts AC to DC then back to AC for no hum, perfect sine wave, balanced and voltage regulated power. These run $1500+
Any experiences or knowlege anyone could share?
Thanks,
Dave
