Looking for an elite pre-amp designed for the most critical listener? Look no further than our STP-SE. The ‘SE’ stands for special edition and as our customers and reviewers will tell you, this piece of equipment is special, indeed.

The STP-SE’s stellar performance and upgrades begin with its wires: Kimber Kable’s patented TCSS wiring, a highly passive multi-gauge, multi-strand, continuous strand pure copper that allows for greater dielectric movement than most other wires in its class. Add to that four oversized power-supply capacitors replaced with our trademark Low ESR “Super Cap,” an extremely low noise floor (<6µV Passive, <18µV active) and a fully balanced circuit and the results are spectacular 3-D imaging and instrument placement.

A 25A Schottky bridge rectifier connected through 164,560+µF of capacitance via our proprietary TRR (Triple-Ripple-Reduction) power supply circuit ensures exceptionally clean power delivery to optimize audio quality. Standard operation in a passive state and gain to boost the signal only when needed brings you the utmost fidelity. The STP-SE’s resistor ladder volume control, built with our discrete proprietary design, guarantees the STP-SE’s volume control is clean, accurate, and transparent.

Our available Stage 1 STP-SE upgrade features our discrete proprietary regulators along with 24 Vishay Z-Foil resistors, four premium inductors, four Schottkey diodes and a Rhodium-plated Furtech fuse. These enhancements which focus on the power supply and input/output buffer circuits present greater fidelity and definition.

The Stage 2 upgrade, includes all of the above plus a Furutech rhodium plated IEC inlet, 48 Vishay Z-Foil resistors located in the resistor ladder volume control, 16 upgraded high frequency filter capacitors and a green OLED display. Direct attention to the signal path throughout the volume control and filtering circuit yields major enhancements to an already exceptional product.
