Audio Research SP20
Code : ARCSP20
RM 43200

The SP20 is a full-function line stage which incorporates a phono preamplifier and, for the first time ever on an ARC preamp, there is a headphone jack. Front panel controls have been minimized to two rotary controls and an interactive touch screen display, along with power, mute and output selector buttons.

The interactive touchscreen has been designed to take full advantage of the feature set the SP20 offers, and operation is intuitive and easy-to-use. Numerous adjustments allows customization to the performance and display of the SP20 for seamless system integration, including input naming and gain offsets, volume presets, and tube hours. System checks have been put into place to alert when tubes have exceeded standard serviceable hours (4,000), and a low line auto mute function engages in the event of a power brown-out.

The SP20 is fully balanced, pure Class-A with zero feedback. There are seven levels of voltage regulation, a large power supply, and a very low-noise R-core power transformer. Both the line and phono stages feature low-noise JFET inputs and 6H30 (2 per section) outputs. The latest high performance coupling and bypass capacitors are used in both stages. Both the line stage and phono preamplifier offer extraordinary frequency response and low noise. The phono section provides 58dB of gain, so the SP20 can be used with a wide variety of phono cartridges, including moderately low output moving coils.

The headphone output is no mere afterthought; it is a low-distortion, high-performance vacuum-tube headphone amplifier designed to comfortably drive a wide impedance range of headphones. The button next to the headphone jack switches off the main (amplifier) outputs for headphone listening, or it switches off the headphone jack for speaker listening.

The SP20 delivers musically, with an ability to effortlessly drive your tube or solid-state amplifier.
