The YPSILON PST-100 MK2 is an impressive entry in the renowned 100 series, representing a significant advancement in preamplification technology. With its innovative design and premium components, the PST-100 MK2 promises an unparalleled audio experience that audiophiles will appreciate.
The Essence of Signal Attenuation
At the heart of the PST-100 MK2 lies a unique approach to signal attenuation, which sets it apart from conventional preamplifiers. While traditional wisdom suggests that the most critical aspect of a preamplifier is its active circuit design, YPSILON contends that the method of signal attenuation specifically, the volume control is paramount to achieving superior sound quality.
Many preamplifier designs rely on resistor attenuators for volume control. However, YPSILON has taken a bold step forward by developing a bespoke transformer for attenuation. This transformer utilizes advanced winding techniques and the highest quality wires and cores, resulting in performance that surpasses the best resistor attenuators on the market. The ultra-linear characteristics of the transformer’s magnetic circuit, combined with premium materials, produce a sound that is both musical and detailed, elevating the listening experience.
Design and Performance Features
The PST-100 MK2 features a transformer attenuator with 31 taps, allowing for a total attenuation of 54dB in its lowest setting. This design ensures that listeners can achieve the desired volume levels without sacrificing sound quality.
The active gain stage employs a no-feedback single-ended C3m triode, which is transformer-coupled for optimal performance. The power supply, which incorporates valve rectification using a 6CA4 and a choke filter, further enhances the audio quality. The wiring is meticulously crafted point-to-point using custom-made pure silver wire, adding to the overall sonic excellence.
Positioned after the valve stage, the transformer attenuator preserves the purity and micro-details of the audio signal, contributing to the PST-100 MK2’s gain of 16dB and a maximum output impedance of 150 Ω. As a result, the PST-100 MK2 stands as the pinnacle of preamplification, making it an essential component for any high-end audio system.
Introducing the PST-100 TA
For audiophiles who do not require the additional gain provided by the valve stage, YPSILON offers the PST-100 TA. This version retains the exceptional transformer attenuators but omits the valve stage, making it a suitable choice for various audio systems. Notably, the PST-100 TA is fully upgradeable to the complete PST-100 MK2 version, allowing users to enhance their setup by returning to the factory for modifications.
Conclusion
The YPSILON PST-100 MK2 is a groundbreaking preamplifier that redefines the standards of audio performance. With its innovative transformer-based attenuation, high-quality components, and meticulous design, it provides an exquisite listening experience that is truly unmatched. Whether you choose the full PST-100 MK2 or the versatile PST-100 TA, you are investing in a component that will elevate your audio system to new heights.
