820S Power Supply Takes Your Evolution 610LP or 810LP Phono Preamp Over the MOON

That's the claim made by simaudio for the Moon 820S power supply, which can be added Evolution products including the 610LP and 810LP as well as the 650D and 750D DAC/CD transports and the company's 740P preamplifier.

Only those who have never experienced what an add-on outboard power supply can do for an already well-designed audio product will be skeptical. However, with a price tag of $8000 one hopes dealers will allow customers an at-home trial before buying.
