Niagara 5000, like new, in perfect cosmetic and operational condition. It's been used in my system for a year and a half+ with zero issues. After testing a few power conditioners, I ended up with the Niagara and never looked back.
From the manufacturer:
"The Niagara 5000 features our patented AC Ground-Noise-Dissipation, the widest bandwidth-linearized AC filter in the industry, and our unique passive/active Transient Power Correction Circuit. Boasting an instantaneous current reservoir of over 90 amps peak, the Niagara 5000 is specifically designed for today’s current-starved power amplifiers. Many AC power products featuring “high-current outlets” merely minimize current compression; the Niagara 5000 corrects it."
