Pre-amplifier
P-307
£1200
P-307 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-307 as
accurate as possible.
To avoid unwanted interactions with adjacent source
components, P-307 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-307 uses a superior attenuator that offers a
neutral sonic performance.

Amplifier R-1.5
£1450
150 Watts x 2 (Class A)
The R-1.5 amplifier is designed to drive any loudspeaker,
producing warm, "tube like" sound quality. It has been
constructed with premium parts, including metal film
resistors and film capacitors, reinforcing Usher's
reputation for high-quality manufacturing. High-power
bipolar transistors, designed by Motorola, can handle
sophisticated power and current requirements. And its
massive AC power transformer works with a high-capacitive
filtering system for the purest sound. Other features
include Burrow-Brown OPA2134P Sond Plus Series op amps,
bridging switch for mono block operation, terminals that
accept both banana plugs and spades, optional balanced
inputs and large handles on the front and rear panel.
