Separate components hold the promise of the best
possible delity, since each device is optimized for
its role in the sound reproduction chain. Rotel has
been designing and manufacturing high performance
components for dedicated enthusiasts for over 50
years. Those decades of experience, along with
precise and efcient in-house manufacturing, are
fully evident in Rotel separates. As countless
reviewers have testied over the years, they rival
and frequently exceed the performance of much
higher priced offerings. The new RC-1570 stereo
preamplier, a blend of cutting edge digital circuitry
with on-board Digital-to-Analog conversation and
classic analog stages, is the latest example.
Beneath the clean lines and user friendly fascia
of the RC-1570 lies highly sophisticated engineering.
Both analog and digital sources have been given
equal consideration as today’s listener often has
several digital sources, but may also enjoy legacy
formats like vinyl LPs. A large toroidal transformer
and regulated power supply ensures stable current
and voltage requirements to all stages under
dynamic conditions. Premium circuit components
have been selected only after extensive listening
evaluations. Careful routing of all low level signals
has been practiced to ensure impressive signal to
noise levels. The result is effortless musical dynamics,
impressive detail and scale.
The RC-1570 stereo preamplier is also extremely
exible. Four digital inputs (2 co-ax and 2 optical),
plus the rear PC-USB handle digital sources up to
24/192 resolution. The 4 inputs are designed for
sources such as TV set-top boxes, at panel TVs
or Blu-ray players for stunning playback. The PC-USB
input makes use of audio playback software such
as iTunes or Windows Media Player to replay music
from your computer digital library. A Bluetooth
dongle is provided to be used with the front USB input.
A premium Wolfson stereo D/A converter handles
critical conversion from digital data to analog. Analog
inputs include balanced XLR connectors (perfect
for connecting the RCD-1570 via its XLR outputs)
in addition to four pair of conventional RCA inputs.
A moving magnet phono stage rounds out the source
capability. XLR and single ended outputs are provided,
as are two 12-volt triggers to control on/off operation
of an amplier and/or other components and RS-232
on a standard DB-9 connector. In short, the RC-1570
is a tremendous value and the perfect upgrade for
owners of older analog-only preampliers.
