I agree that my experience indicated that no conditioner sounded better after back and forth comparisons. But you have to try them for yourself. If you already have a conditioner that you feel works for you, then move on to another part of your system that you feel may need to be improved.
Power Conditioner
I currently have a Torus RM20 power conditioner. Has anyone compared the RM20 to any Shunyata or IsoTek power conditioner? What Shunyata or IsoTek power conditioner do you recommend I compare to the RM20? Is it better to have one power conditioner for lower power components and a separate conditioner for the amplifier?
