№5805 ANALOG INPUT STAGE
The foundation of the №5805 is its proprietary
PurePath circuitry – a fully discrete, direct-coupled,
dual-monaural line-level preamp circuitry,
for which the Shelton design team has filed two
patent requests. A unique single gain stage mated
to a digitally controlled resistor network for volume
adjustment maintains maximum signal integrity
and widest possible bandwidth. Each of its three
stereo line level inputs—one balanced XLR and two
single-ended, using custom Mark Levinson RCA
connectors—has its own individual high-reliability
signal switching relays. The MainDrive headphone
output employs a preamp output stage specifically
designed with the current and power capacity to
drive headphones directly in pure Class A,
without a separate headphone amp.
A newly designed phono stage features a hybrid
gain topology, mating key discrete components
from the acclaimed 500 series Pure Phono
stage with low-noise integrated circuits for high
performance at lower cost. Also like the 500 series,
a hybrid active/passive RIAA equalizer employs
precision resistors and polypropylene capacitors
for exceptional accuracy and sonic clarity. The user
can select MM/MC gain and optional infrasonic
filter from the setup menu, while capacitive and
resistive loading settings are easily accessed from
the rear panel.
