About the ST-85

The VTL ST-85 is a tube stereo power amplifier designed to provide an engaging and true-to-life listening experience. It uses four EL34 output tubes and four 12AT7 tubes, delivering 60 watts per channel in tetrode mode and 30 watts per channel in triode mode into 5 ohms. The amplifier operates in Class AB1 and features a compact chassis with short signal paths for optimal sound quality. It is praised for its musicality, accurate bass control, and ability to create a coherent, three-dimensional soundstage. The amplifier includes a tetrode-triode switch to select output power and sound character, with tetrode mode suited for dynamic music with bass punch and triode mode for delicate, intimate music. It has a robust build with an extruded aluminum front panel and a tinted glass window to view the glowing tubes. The ST-85 is suitable for satellite, mini-monitor, or small floor-standing speaker systems and is considered a great value in the audiophile market.
