Power/voltage Regulator

It will also depend on how unstable the voltage is in your area . When I was using a power stabilizer ,with read out , the voltage would drop by 15V at times . Base voltage here is 117 . One would think thats got to make a difference with many components .

Yes . the regulator should be up stream of the conditioner , they may work well together . I have A Panamax 5510 , now being used for video , One of the better conditioners in my opinion . Make sure you listen closely before making your mind up on anything .
