Quad 34 Preamp Upgrade - Stage 3 replaces the original, undersized power supply with our offboard, low noise psu. The new power supply arrangement has dedicated positive & negative supplies replacing the original noisy "rail splitter" type.

The transformer is replaced with a larger, higher current toroidal type which has better regulation. Much larger, FT-Cap / Mundorf low esr smoothing capacitors remove more ripple from the voltage rails and the voltage regulation is an enhanced version of our discrete low-noise Quintessence voltage regulators.

You hear a much more detailed and cleaner sound combined with more clarity and smoothness. Non of the graininess of the original design remains. Bass, dynamics, openness are dramatically improved and the sound becomes much more natural and realisic.

A massive step-up in performance.
