Our Quad 44 Preamp Upgrade - Stage 3 really does have to be heard to be believed! It consists of again replacing critical signal path components and opamps with far superior sounding modern audio types.

The main upgrade however, comes from our incredible off-board power supply.

This external psu contains a massive, over-specced toroidal transformer with the finest sounding components available.

Inside this case is a bespoke circuit board featuring the latest development of our "Quintessence" super-low-noise discrete voltage regulation to replace the standard, noisy circuit contained in the preamp.

The end-result is an incedibly clean, detailed & dynamic preamp capable of competing with modern units costing several thousand pounds.
