Wyred 4 Sound SX-500

Original purchase from Wyred4Sound. Consecutive serial numbers; just under 2 years old. Extremely well cared for - used in a bedroom system. I am rating as a 7/10 because of two very small paint chips and a few hairline scratches, both of which can be seen in the images, and neither of which affects the performance of these fine amps.

The amps will ship in the original factory cartons, which consist of a carton for each amp, then a master carton for the pair.

From the Wyred4Sound website:
Versatility in the form of complete channel separation functions to optimize sound quality and amp placement. Closer proximity to speakers means shorter cable runs and enhanced speaker control. Our award winning SX series of amplifiers offer the discerning audiophile the cleanest, most transparent sound available from any power source on the market. Ultra robust power amp topology provides stability down to 2 ohms and the efficiency to remain cool in the most demanding applications.
A proprietary FET input buffer allows both XLR and RCA input options while feeding the power amp with a ultra-low noise, low distortion signal. High quality WBT binding posts and Kimber Kable TCX wiring complete the signal path with ultimate purity. The result of our obsession with technology is an expansive, transparent listening experience allowing every instrument to shine through.
