About the C 525BEE

The NAD C 525BEE is a dedicated Red Book CD player designed as an affordable audiophile source component. It plays standard audio CDs as well as CD-R and CD-RW discs recorded in 16‑bit/44.1 kHz PCM format. At its core is a 20‑bit Burr‑Brown sigma‑delta digital‑to‑analog converter, working with an 8x‑oversampling digital filter and a 4‑pole analog output filter to achieve very low distortion and excellent linearity. The C 525BEE’s analog and digital sections have separate voltage regulation to reduce interference between circuits and lower the noise floor. The analog output stage uses quality Burr‑Brown operational amplifiers along with carefully selected metal‑film resistors and polypropylene capacitors in key locations for accurate frequency response. Output is provided via gold‑plated stereo RCA jacks, and a transformer‑isolated 75‑ohm coaxial digital output is included for use with an external DAC or digital recorder. Performance specifications include a frequency response of 5 Hz to 20 kHz (±0.5 dB), total harmonic distortion around 0.003–0.0035%, a dynamic range in the high‑90 dB region, and a signal‑to‑noise ratio of roughly 106–108 dB. Output level is around 2.1–2.2 V RMS at 0 dB, with an analog output impedance of approximately 300 ohms. Channel separation is very high, exceeding 90 dB at 1 kHz. The front panel layout is simple and functional, with a central backlit LCD display showing track number, time, and total tracks, plus direct buttons for play/pause, stop, open/close, skip, scan, random, repeat, and time display. The player includes programming for up to 20 tracks, random play, repeat (track or disc), and track delete functions. A full‑function remote control is supplied, and the unit can also be controlled by compatible NAD system remotes from matching amplifiers. The C 525BEE is housed in NAD’s classic, understated metal chassis with a rigid construction to reduce vibration. Typical dimensions are about 435 x 70–80 x 285 mm and weight is about 4–4.1 kg, making it compact enough for most hi‑fi racks while still feeling solid and substantial. Though now discontinued, it remains respected for delivering clean, musical CD playback and strong value in modestly priced two‑channel systems.
