The ST mkIII Series is the amplifier you've been waiting for. This is where your music finally sounds the way it was meant to be heard!

Powered by ICEpower's revolutionary ICEedge topology and a meticulously engineered 3rd generation input stage, these amplifiers unlock details you didn't know existed in your favorite recordings. Silky smooth top end with precise attack and decay that's coupled with bottom end authority. Every note, every nuance, rendered with absolute clarity and available in 3 power levels to suit your exact needs.

Premium 14AWG OFC wiring soldered to gold-plated 5-way binding posts. Dual differential common mode converters fed from quad FET buffers. Balanced or unbalanced input signal arrives perfectly preserved, delivering reference-grade audio quality that refuses to compromise. This is the amplifier that transforms good systems into legendary ones. The one that allows you to discover your music all over again. Unlike other purchases you may have made, this one justifies every dollar spent. Don't settle for less.

Unlock even greater sonic magic with optional Kimber TCX multi-gauge/strand OFC wire for improved transparency and German-engineered WBT nextgen® binding posts for the optimum high purity/low mass connection. You and your system deserve it!
