The vintage Quad 33 is capable of incredible transparency. It is a fully discrete design, containing no opamps. Whilst this can bring benefits in transparency and detail, it also means it is incredibly sensitive to power supply noise. To combat this issue (and due to a great many requests from customers) we have developed a custom power supply board (PSU). This new Quad 33 PSU uses an on-board, low-noise toroidal transformer, high quality capacitors and improved voltage regulation over the original.
With the Quad 33 PSU fitted you will hear exceptional timing, massively improved levels of detail allied to a delicate treble reproduction and extended bass.
Dynamics are improved too as are sound-staging, separation, depth and realism.
