I have this Furman and I am very pleased with it. The voltage output is dead on at 120VAC. It did take a while to start sounding good, long break-in period. At first I thought I made a mistake because my system did sound as good as before, but I know how it is when it comes to break-in times so I left it on for a week. It was sounding better, left it on for another week. The system was sounding way better and it the best it has ever sound. I'm glad I got this power conditioner/voltage regulator.
