I second what @cleeds says. If the aluminum wiring hasn't been evaluated yet by a professional electrician, it's a high priority to get that done.
Importance of a power conditioners versus surge protector
Hi everyone! I recently upgraded my stereo and realized that I have had trouble with power outages and some “glitches” on my tv for a while. I purchased a Furman surge protector but it is not a power conditioner. I guess while the surge protector may be good for abnormally elevated “electronic surges” it may not filter unwanted noise and protect my system. I have aluminum wiring in the house also which I know isn’t the best conductor. Is it important from a music quality and component standpoint to add a conditioner? Can you suggest a quality conditioner for under $750?
