Description: For sale is a Wyred 4 Sound STP-SE Stage 2 preamp in black. Preamp is in excellent condition, no scratches, and with the green OLED display indicative of the Stage 2 upgrade. Decent discount off new, current list price at Elite Audio is £3,749 I operate in the passive zone, up to 2/3 of range, and it is extremely quiet and defining. It is still extremely quiet moving into the gain range. Superb sounding preamp often compared to $10,000 preamps. (6moons, 10 Audio, High Fidelity) Ignore the voltage rating on the back of the unit - the unit is currently set to 220-240vac UK Voltage, but can be switched to 110vac by simply removing a cable inside the was supplied to me by Wyred4Sound. Very easy job. Wyred 4 Sound’s website description: The STP-SE’s stellar performance and upgrades begin with its wires: Kimber Kable’s patented TCSS wiring, a highly passive multi-gauge, continuous strand pure copper that allows for greater dielectric movement than most other wires in its class. We then add 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. Stage 1 Upgrade Our available Stage 1 STP-SE upgrade features 24 Vishay Z-Foil resistors, four premium inductors, four Schottkey diodes. These enhancements which focus on the power supply and input/output buffer circuits present greater fidelity and definition. Stage 2 Upgrade The Stage 2 upgrade includes all of the above plus our discrete proprietary regulators, an upgraded IEC inlet, 48 Vishay Z-Foil resistors located in the resistor ladder volume control, 16 upgraded high frequency filter capacitors, a Premium upgraded fuse, 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.
