I tried the step down version of your balanced AC power conditioner (500W. Step down 230Vac to
100Vac) on my Japanese import 100V luxman CD Player and Amplifier. No contest. All performance
spectrum is improved. Details, bass, speed, dynamics, body are all way better than the 1KW generic
one I got. Best of all there is no transformer hum at all (which I experienced with my generic
transformer)! I have got a buzz (which I suspect is a ground loop issue) over my speaker output which
is solved as well with your AC conditioner.
Now I do not feel that I am compromised when I use Japanese 100V products in Singapore.
