Introducing the evolution of our most powerful monoblock amplifier, the SX-1000R. The new SX-1000R amplifier delivers over 1000 watts and offers the discerning audiophile the cleanest, most transparent sound available from any power source on the market. Utilizing an all-new input board, the SX-1000R is smoother, more refined and more engaging than the original SX-1000, yet still retains the awesome power that puts it head and shoulders above the competition. Ultra robust power amp topology provides stability down to 2 ohms and the efficiency to remain cool even 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. WBT nextgen™ binding posts and Kimber Kable TCX wiring come standard — completing 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. The SX-1000R is further identified by its moniker on the backplate and a smart looking custom color option - Anthracite Gray. Also available in black.
