Introduces PST 100 Anniversary Pre Amplifier featuring nanocrystalline core transformers with ultra-pure silver windings.
Point-to-point wiring with silver eliminates capacitors for enhanced audio purity.
Power supply upgrades include high-quality film capacitors and amorphous choke filters for quieter background and dynamic range.
Ypsilon Audio marks its 30th anniversary with the introduction of the PST 100 Anniversary Pre Amplifier at Audio Show Deluxe 2025. This special edition builds upon the acclaimed PST 100 SE, maintaining the use of C3m pentodes with one per channel, ensuring the signature sonic quality that enthusiasts appreciate.
A standout feature of the PST 100 Anniversary is the incorporation of nanocrystalline core transformers with silver windings at both the input and output stages. This advancement supports an ultra-pure circuit topology in the active gain stage, minimizing signal loss and enhancing transparency. Additionally, the preamplifier is entirely point-to-point wired using ultra-pure silver wire, which preserves audio integrity by eliminating capacitors from the signal path.
The power supply has been meticulously refined with high-quality film capacitors replacing electrolytics, paired with a double C-core amorphous choke filter boasting very high inductance. These enhancements contribute to a quieter background and a more dynamic range, addressing critical aspects of sound purity and performance.
Visually, the PST 100 Anniversary features a redesigned front display with larger symbols and customizable color options, aligning with Ypsilon's commitment to both aesthetic and functional excellence. The combination of premium materials and thoughtful engineering underscores Ypsilon's dedication to delivering top-tier audio experiences.
The Ypsilon PST 100 Anniversary Pre Amplifier will be showcased at the Whittlebury Park Hotel on March 22nd and 23rd, 2025. Audio enthusiasts attending the event will have the opportunity to experience this milestone release firsthand, celebrating three decades of Ypsilon's contribution to high-fidelity audio.
