The Genz-Benz's Streamliner STM-900 is their 900 watt version of the Streamliner design. The 300 volt All Tube Class A preamp design is driven by three 12AX7 preamp tubes utilizing six gain stages. The preamp design features an intuitive and highly effective tone network which is a unique blend of a modified passive Baxandall network for the bass and treble along with an active tube driven mid filter with selectable mid frequencies. The versatile all tube preamp exudes a fat and rich tone that remains articulate.

The 3DPM adds heft and girth to each individual note, while enhancing the amplifiers responsiveness and headroom. It provides the dynamic and 3-dimensional tone and feel of an all tube power amp design.
