From Westminster Lab
Westminster Lab designed the Quest to sit between your sources and its Rei amplifier. The team started by asking whether a system needs a preamp at all, then rebuilt each stage around what a preamp should add.
It's balanced throughout: 3 XLR inputs, 2 XLR outputs, 12Vrms of output and 6.5dB of gain. Distortion measures under 0.0001% at 1kHz, and both signal-to-noise and channel separation clear 120dB.
The 2 module slots take it further. The MC/MM phono module sets gain from 40 to 70dB, impedance from 60 ohms to 47k in 18 steps, and capacitance from 22 to 322pF. There's also a DS Audio equaliser module for DS Audio cartridges and an RCA input module for unbalanced sources.
