Rotel RC-1590 Owner's Manual page 20

It's all about control.
The RC-1590 stereo preamplifier has been engineered
to the highest audio performance levels and provides
an incredible level of control and flexibility for the
user. Starting with a high performance power
supply consisting of two Rotel custom built toroidal
transformers for maximum efficiency and low magnetic
fields, these transformers provide low-noise isolation
between the analog and digital signals. They are part of
a reference-grade power supply consisting of individual
analog and digital regulator circuits with custom-made
slit-foil capacitors. Slit-foil capacitors have very quick
charge/discharge times and low signal loss ensuring
tight bass performance.
Rotel engineers wanted to create a reference quality
stereo preamplifier to match with our new RB-1590
stereo power amplifier. Every aspect of component
selection and circuit topography was designed and
carefully evaluated during multiple listening sessions
to ensure the highest fidelity. For example, analog and
digital circuits were designed separately, by specialized
Rotel teams. Analog inputs are all very low noise
circuitry and include a high performance moving magnet
phono stage. Digital inputs are fully isolated and feature
