P-307
MSRP: $2,280
|
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, the 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. The P-307
completes any high-end sound
system by allowing you to
control and appreciate the
subtle nuances of your music.
