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!
