Key specs that matter

Four balanced XLR inputs and four single-ended RCA inputs are provided, with three balanced and three single-ended outputs - a comprehensive eight-input, six-output connectivity set. Input impedance is a high 120k ohms balanced or 60k ohms single-ended, with output impedance at 600 ohms balanced or 300 ohms single-ended. Maximum balanced output capability reaches an extraordinary 70V RMS - a remarkable figure providing exceptional headroom. Frequency response spans an extraordinary 0.4Hz to 200,000Hz within plus-or-minus 3dB. Total harmonic distortion plus noise is 0.01%. At 480 x 198 x 419mm and 17kg, the Reference 6SE Line-Stage represents Audio Research's flagship-tier preamplifier engineering.

Sound and use context

Expect exceptionally clean signal handling reflecting the extraordinarily wide 0.4Hz-200kHz bandwidth combined with the extraordinary 70V RMS maximum output capability, representing Audio Research's most accomplished current engineering ambition.

Pairing

The comprehensive eight-input, six-output connectivity comfortably accommodates an elaborate multi-source, multi-amplifier system, and Audio Research's own Reference 330M or S-100 power amplifiers offer natural, brand-coherent pairings.
