DESIGN PHILOSOPHY

From a distance you can see that the design of the Plinius products is more than an applied styling exercise to the front panel. We have started from the ground up to produce a casing for our electronics that is unrivalled in its physical strength and visual simplicity. Wherever possible we have reduced the number of parts needed and then invested massively in refining and producing the remaining parts to the highest quality achievable with state of the art computer controlled machines allied with expert craftsman. Examples of this approach include the hydraulically formed corners on the amplifiers giving much greater strength and the one piece housing for the remote control unit that eliminates large joints and potential creaks.

The very process of holding the remote tells you that you are controlling both a powerful and precise product. It is designed specifically for the act of listening to music, not channel surfing on a television or changing the room temperature. The distinction is important because we believe that listening to music is a highly selective and emotional experience that requires a much greater level of concentration and precision to fully appreciate and enjoy.

As with music that you are not familiar with, truly innovative new designs can take time to understand and enjoy. How often have you heard music that you were first unsure of, that over repeated listening, has become a firm favourite. Our designs are fundamentally different to many other companies, and we hope that you will take the time to explore their unique character and qualities because we have not made them different simply to be different. We genuinely believe that their visual and tactile qualities do improve the experience of listening to music and that is our design goal!

SA-103 specifications

Plinius Audio SA-103 is an exceptional power amplifier designed for audiophiles seeking high-quality sound reproduction combined with robust performance. Renowned for its distinctive warm tone and ability to drive a wide range of speakers, the SA-103 stands out in the realm of high-fidelity audio equipment.

One of the primary features of the SA-103 is its impressive power output. Delivering 100 watts per channel into an 8-ohm load, and doubling that output into 4 ohms, this amplifier can effortlessly drive many speaker types, making it versatile enough for both dynamic home theater setups and demanding stereo listening environments. The amplifier’s dual mono design ensures that each channel operates independently, reducing crosstalk and providing a cleaner soundstage with greater separation between the left and right channels.

The SA-103 utilizes Plinius' unique “Class A biased” architecture, which enhances sound quality by delivering a warm, natural tone. This design minimizes distortion and provides high linearity throughout the amplifier's operating range. The added flexibility of a switchable gain setting allows users to adjust the output to suit their specific system requirements and room acoustics, ensuring optimal performance in various environments.

Another standout characteristic of the SA-103 is its robust construction. Built with high-grade components, including a heavy-duty transformer and custom-designed capacitors, the amplifier boasts durability and longevity. The premium build quality is not just for looks; it also contributes to reducing resonance and vibration, further enhancing audio clarity.

The input stage of the SA-103 features sophisticated circuitry that provides an incredibly low noise floor. This is particularly beneficial for critical listening sessions where high sensitivity is essential. Additionally, the amplifier is equipped with high-quality binding posts and XLR inputs, allowing for secure connections and compatibility with various audio sources.

Heat management is addressed efficiently in the SA-103, utilizing large heatsinks and a cooling architecture that ensures the unit operates smoothly even during extended use. Overall, Plinius Audio SA-103 represents not only an investment in high-performance audio gear but a commitment to delivering a pristine listening experience, characterized by depth, balance, and expressive detail. For anyone serious about audio quality, the SA-103 remains a compelling choice in the power amplifier landscape.
