What our bench covers →NAD 5425 Remote Control CD Player MASH 18-Bit, With Remote
A clean, capable, and musically satisfying CD player from NAD’s highly regarded 5400 series, the Model 5425 delivers the honest, engaging sound that made NAD a trusted name in affordable hi-fi — complete with remote control, in very good condition.
The NAD 5425 occupies a special place in the history of budget CD players. When reviewed by Stereophile at its $299 USD launch price, it earned a genuine recommendation — praised for an “overall ease” and musical coherence that bested CD players costing two and three times as much, including the $750 Denon DCD-2560 and the $900 Sony CDP-X555ES. That legacy speaks to NAD’s core design philosophy: rather than chasing specification numbers or adding unnecessary circuit stages, NAD focused on simplicity, clean signal paths, and careful circuit implementation to achieve sound quality that exceeds what the price would suggest. The 5425 uses a MASH 18-bit DAC (Matsushita MN6471M) with 4x oversampling, balanced analogue outputs summed through a minimalist 5532 op-amp stage, and a well-executed five-pole active filter — a topology that still holds up well against many later players.
The 5425 is the remote-equipped version of the 5420, and the difference matters for daily use: the included remote allows full transport and programming control from your listening seat, making this a practical as well as sonically rewarding choice. The LCD display supports programming and repeat play modes, with memory for up to 16 tracks, and the fixed 2V RCA output connects cleanly to any integrated amplifier or receiver. The Sony KSS-210A laser mechanism is robust and well-supported, and a good-condition example like this one remains a reliable daily player.
NAD’s circuit simplicity approach means there are fewer gain stages between the disc and your amplifier — the result is a transparency and naturalness that many listeners prefer to the more processed sound of more “feature-rich” players of the same era. For vinyl listeners adding a CD source to a turntable-based system, or for anyone wanting honest, unfussy digital playback, the 5425 is an excellent choice that continues to be sought after on the used market.

NAD began in London in 1972 as New Acoustic Dimension, a brand created by a group of hi-fi distributors and led by American audio executive Martin L. Borish. Since 1999 it has been part of Lenbrook of Pickering, Ontario, which also owns PSB. We carry NAD stereo receivers and AV receivers, integrated and power amplifiers, phono preamps and CD players. We've had more than 110 NAD listings so far, covering nearly 70 different models. Every used NAD here is inspected, tested and serviced as required, then photographed in-house and covered by our Bumper-to-Bumper Warranty and Perpetual Trade-Back Program. Don't see the model you want? Tell us on First Dibs and we'll email you when one arrives.
Our five best-selling NAD models so far: the 2150 power amplifier, the 705 and 7020e stereo receivers, the T 531 DVD and CD player, and the 7140 receiver.
The NAD story, 1972 to today
NAD began in London in 1972, when a group of hi-fi distributors organized by Martin L. Borish, then of Acoustic Research, planned a new brand of affordable electronics they could sell: New Acoustic Dimension. Borish left his post as president of Acoustic Research in 1976 to run NAD full time, and in its early years NAD was run from his London apartment.
The 3020. Norwegian-born engineer Bjørn Erik Edvardsen designed the NAD 3020 integrated amplifier, introduced in 1978 at 20 watts per channel and built in Taiwan. It sold well over a million units, and Stereophile named it one of the 100 most significant audio products of its first 40 years. NAD calls it the best-selling hi-fi amplifier in history.
From distributors to owners. Lenbrook became NAD's Canadian distributor in 1978. In the 1990s NAD was owned by the Scandinavian distributor AudioNord, and in 1999 the Lenbrook Group of Pickering, Ontario, bought it.
Today. NAD is still part of Lenbrook, alongside PSB and Bluesound. Its range runs from C-series integrated amplifiers such as the C 320BEE, named with Edvardsen's initials, to direct-digital designs and the Masters Series. The C 3050 LE of 2023, a 50th-anniversary model, was limited to 1,972 units.
Which NAD is which?
1970s receivers: early models such as the 160 and 160a.
The 3020 family (from 1978): the 3020 and 3020e integrated amplifiers, and receivers such as the 7020 and the 7020e of 1988, which shares the 3020e's amplifier section.
1980s amplifiers: the 3140 and 3150 integrated amps and the 2150 and 2200 power amps, many with NAD's soft-clipping and bridging switches. Our best-selling 2150 is a 50-watt-per-channel power amp from the early 1980s.
Later receivers: the 7140 (about 1984 to 1989), the Monitor Series 7100 and its siblings from 1988, and the 705 of the early 1990s.
Home theatre: T-series AV receivers such as the T 757, whose Modular Design Construction lets the receiver be upgraded with new modules, and the T 531 DVD and CD player.
C-series and Masters Series (2000s on): the C 320BEE and later C-series integrated amps, the direct-digital C 390DD, and the Masters Series.
Buying used NAD: what to check
Pre-out and main-in jumpers. Many NAD integrated amps split the preamp and power amp at the back panel. If the jumpers between pre-out and main-in are missing, the inputs play nothing, so make sure they are there.
Switches on the back. Many 1980s NADs have soft-clipping, bridging or impedance switches. An amp that sounds wrong may just have one set oddly, so check every switch before blaming the amp.
Age. Technicians restoring 3020s report blown fuses, failed output transistors and leaky capacitors, and reviewers call cleaning the selectors and volume control almost mandatory on 1980s units. Ask what has been done.
Receivers. On late-1980s Monitor Series receivers, test every front-panel button, both speaker relays and the preset memory. The 7140's display can fail, though it can be repaired.
Disc players. Play both a CD and a DVD in a T-series player before you buy.
