Sorry, This product is no longer available



The Usher P-307 is a modern, reference-level preamplifier. It is the control center of today's high-end sound systems. Its two main functions are source selection and volume control — and Usher has made every effort to keep that input as accurate as possible. To avoid unwanted interactions with adjacent source components, using 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. This excellent preamplifier completes any high-end sound system by allowing you to control and appreciate the subtle nuances of your music.
