Developed from the acclaimed NAD 5425 CD player, the 502 with NAD Link incorporates a fully revised
internal layout and superior components to optimise performance, providing a CD player which out
performs many other manufacturers more expensive machines.

The MASH single bit converter delivers distortion-free sound from its sophisticated D to A circuitry The
digital output can be linked to any outside digital recorder, DAT, DCC or mini disc, or to a digital
signal processor making the 502 ‘future proof’.

The 502 is remarkably capable for its cost and the US journal ‘Stereophile’ said in April 1994 “You won’t
do better for twice the money”.
