Just plug in a free AC wall socket. It just makes everything better. From top to bottom everything sounds better.
From the High Fidelity website:
Stereotimes' most wanted component, The MC-0.5 is a magnetic conduction device. Covered under the connector is a series of patented products. This unique device simply plugs into the wall to apply magnetic conduction to incoming electricity. The MC-0.5, once plugged into an extra outlet, delivers a dramatically cleaner, clearer music signal with better dynamics, realism and musicality. It is both more detailed as well as more relaxed-sounding at the same time.
Although moderately priced in comparison to some power conditioning products, the MC-0.5 will offer an improvement to all audio systems. It also works with conventional power conditioners to restore extra realism, speed and clarity. Although meant for reference audio systems this device can be used on literally anything including televisions and home theater systems. Just find an extra outlet to plug the MC-0.5 in and enjoy improved picture clarity and music resolution
A line conditioner that works. It cleans up the power going to your equipment. Simple as that. Where you can tell is when you listen to voices - they sound clear and without grain. Bass isn't muddy or oversaturated.
They are used and have one or two scratch on them. Since they are plugged in the AC sockets, you can hardly see the scratches.
