The NAD 513 is a compact disc player that offers a solid audio performance with a classic aesthetic typical of NAD products. Released in the mid-1990s, it features a relatively simple design, accommodating up to three discs at a time. Audio enthusiasts commend its sound quality, particularly for genres like jazz, highlighting its detailed bass and crisp treble. However, the model has received mixed reviews regarding build quality and mechanical reliability. Common issues reported include a poorly designed disc drawer that tends to operate slowly and awkwardly, as well as display malfunctions after periods of use. Despite these drawbacks, many users express satisfaction with the audio output, often considering it a value-oriented choice when acquired at a discounted price. On the downside, there have been mentions of reliability concerns, with some owners experiencing power supply failures and other mechanical problems that deter long-term use without repairs.
