Cary Audio SLI-80HS

Cary Audio
The SLI-80 integrated amplifier has long been considered the benchmark for vacuum tube integrated amplifiers worldwide. Cary Audio's foray into the world of vacuum tube music systems has resulted in a truly remarkable product. Music enthusiasts across the globe have been captivated by the exceptional qualities of this amplifier.

The newly introduced SLI-80HS (Heritage Series) stays true to its esteemed heritage. Its circuit design minimizes feedback, resulting in unparalleled transparency and intricate musical detail. Despite its rated power output, the amplifier delivers impressive bass texture and impact. The addition of solid-state rectification enhances the pace, dynamics, and bass detail compared to previous versions. The depth and transparency of the sound will astonish you, making you turn your head in disbelief as if the musicians were performing live before your eyes. The amplifier features toggle switches that allow you to choose between triode mode, providing 40 watts per channel of pure Class A power, or ultra-linear mode, doubling the power to 80 watts per channel in Class AB. Whether you prefer subtle music with exquisite inner detail or crave a high-powered and dynamic experience, the choice is yours!

Klipsch, a renowned loudspeaker company, has been using the SLI-80 in combination with their award-winning Heritage Series product line at various audio shows worldwide for several years now. The synergy between the two is truly astounding, from the iconic Klipschorns to the Heresy III and everything in between. Building on this successful collaboration, Cary Audio has partnered with Klipsch to design a version of the SLI-80 that perfectly complements the aesthetics of their Heritage Series loudspeakers. Optional Black Ash, Cherry, and Walnut wood side panels are available to match the various finishes of the Klipsch Heritage Series loudspeakers. The visual impact is truly breathtaking!


"In my system, the tubed SLI-80HS sounded great with conventional loudspeakers and horns alike, and with all styles of music. It provided an uncluttered pathway to musical satisfaction, LP after LP. The Cary possesses all the qualities tube aficionados seek—and, perhaps due to its solid-state rectification, good if not spectacular grip on low-end fundamentals. Most important—and here's where it shares more than just wood-finish choices with Klipsch—it's tremendous fun."
