This powerful amplifier from Wyred 4 Sound is a must-have for any audio enthusiast. Crafted with precision and featuring advanced technology, this STP-SE model is sure to impress. Ideal for use in a range of settings, from home audio setups to professional studios, it delivers crisp, clear sound that will take your listening experience to the next level. The STP-SEs stellar performance and upgrades begin with its wires: Kimber Kables 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 (<6V Passive, <18V 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+F 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-SEs resistor ladder volume control, built with our discrete proprietary design, guarantees the STP-SEs volume control is clean, accurate, and transparent. NOTE: I am including information about the stage 1 upgrade as that is what I was told it has by the person I purchased it from. However, Wyred4sound was unable to look up the information without the original purchasers information and I do not have the paperwork to prove it. 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.

Wyred 4 Sound STP-SE Excellent Shape - Store Demo.

Used a couple times when I have my W4S amplifier. Unbelievable build quality, compatible with most W4S amplifiers.

Wyred 4 Sound STP-SE Stage 2 Stereo Preamplifier (excellent). This listing is for the Wyred 4 Sound STP-SE Preamplifier with the stage 2 factory upgrade shown in the photos. This is the top-of-the-line preamp, with the highest upgrade possible from the factory. I purchased the preamp new from WFS, and sent it back later for the upgrade. This is by far the best preamp I have ever had, and one of the best I have ever heard, and I have heard a lot! There are reviews online about this unit if you are not familiar. The physical condition is near flawless, and it performs, and functions as new. It comes with the factory remote that works, but it has the rubberized finish that tends to get sticky over time. WFS sells an aluminum remote that you may want to consider. It will be packaged in the factory box, and packaging material for safe shipping, and additionl insurance provided Good luck.
