The Usher P-307A is the control center of today’s high end sound systems. Its two main functions are source selection and volume control. Every effort has been made to keep P-307A as accurate as possible.

To avoid unwanted interactions with adjacent source components, P-307A uses high-quality relays and switching designs to ensure that every source is intact. Thus all sources remain separate from one another and from the power amplifier and cables.

In the digital age, analog preamplifiers remain the most reliable and neutral-sounding component of controlling volume. P-307A uses a superior attenuator
that offers a neutral sonic performance.

Since AC power supply generates noise, P-307A′s power supply is housed in a separate chassis. Thus P-307A′s audio circuits are exposed only to quiet, regulated DC power and the audio signals itself.

USHER P-307 is a modern, reference-level preamplifier. After all, it is only when P-307A reveals the palpable imaging focus and soundstage, the sense of ease and rhythmic flow, as well as the delicate subtlety of musical details that make listening to music a real enjoyment.
