The Quicksilver Audio Full Function Preamp is a stereo tube preamplifier designed for audiophiles seeking excellent sound quality and reliability. It features a line stage with a bandwidth from 1Hz to 650kHz, 27 dB gain, and 100k ohm input impedance. The phono stage supports a bandwidth of 20Hz to 20kHz with 39 dB gain at 1 kHz. The preamp uses a complement of tubes including 12AX7, 12AU7, 12FQ7, and a 5AR4 rectifier tube. It delivers maximum input of 30 volts RMS and maximum output of 65 volts RMS for the line stage. The chassis measures 17"x11" with a front panel of 19"x5.25" and weighs 21 pounds. This preamplifier is hand-built and known for its superior sound staging and depth, often compared favorably against other high-end preamps.
