Cary SLI-80HS integrated valve amplifer

Cary SLI-80HS integrated valve amplifer


Brilliant valve amplifier that works well with many speakers. Superbly detailed without losing that valve smoothness and warmth. Switch to ultralinear for double the output oomph,…nice! We love these with the big Celestion 66‘s and most of the Klipsch range.

For many years the SLI-80 integrated amplifier has been the standard by which all other vacuum tube integrated amplifiers are judged…period! As Cary Audio’s entry into the magic of vacuum tube music systems, it’s nothing short of stunning. Thousands of music lovers all over the world have heard and seen the virtues of this spectacular vacuum tube integrated amplifier.


For several years now, the world renown loudspeaker company, Klipsch, has been using the SLI-80 at various audio shows around the world in combination with their award-winning Heritage Series product line. From the famous Klipschorns to the Heresy III and all models in between, the combination is amazing. As a result of this collaboration, Cary Audio has partnered with Klipsch to design a version of the SLI-80 to directly complement their Heritage Series product line. Black Ash, Cherry, and Walnut wood side panels are available below as an additional accessory of the new SLI-80HS (Heritage Series) integrated amplifier to match the various finishes of the loudspeakers in the Klipsch Heritage Series. The visual effect is amazing!

The SLI-80HS has a removable cage cover available at an additional cost.
