The NAD S 500 is a CD player that is recognized for its strong build quality and aesthetically pleasing design. It weighs approximately 8 kilograms and features a robust aluminum front and side panel. The player operates with a surprisingly high temperature during use, indicative of its construction. The design includes a unique button layout for functions like 'OPEN' and 'STOP', and is supplemented with a blue display. Rear connectivity options include symmetrical XLR connectors. In terms of performance, the player offers a sound signature that is warm and transparent, with a slightly extended mid-range that may or may not complement various speaker setups. Auditions with various audio systems have demonstrated that the audible differences between the NAD S 500 and similarly priced competitors are subtle, suggesting that the choice may come down to subjective preference rather than a stark improvement in sound quality. The S 500 can be controlled by certain TV remotes, though this may lead to unintended interactions.
