Silver faced unit, un-used, new, - a favorite amplifier here at Quantum.

For many years the SLI-80 integrated amplifier has been the standard by which all other vacuum tube integrated amplifiers are judged. Spectacular.

The Cary SLI 80 is a true “high-end” exotic tube integrated amplifier with careful design, parts selection and proper circuit topologies that contribute to an incredible, reliable and enjoyable amplifier.

The preamplifier circuit is a resistive coupled Class A triode voltage amplification stage. Within its power range, the SLI 80 is capable of switching between 40 Watts Triode or 80 Watts Ultra-Linear modes.
