NAD 7225PE — Twenty-Five Honest Watts That Get Stronger as the Load Gets Harder

A small, unfashionable, genuinely clever receiver from the years when NAD was quietly embarrassing companies charging three times as much.

Power Envelope

The number on the front says 25 watts per channel, and that number has been misleading people for nearly forty years. NAD’s Power Envelope supply was built on the observation that music is not a sine wave — it is mostly quiet with brief violent peaks — so a power supply sized for continuous output is sized for the wrong job. The 7225PE holds 25 watts per channel indefinitely into 8 ohms with both channels driven, which is an honest rating measured the hard way. Ask it for a transient and it delivers 60 watts into 8 ohms, 85 into 4, and 90 into 2.

Stronger Into Harder Loads

Read that sequence again, because it is the whole point. Most budget receivers get weaker as the load gets harder, running out of current and going sour into a demanding speaker. This one gets stronger. That is why a 25-watt NAD drives speakers that make 60-watt receivers of the same era sound strained, and why these have kept a following among people who own difficult small speakers. A rear-panel impedance selector lets you tell it what it is working into, and the speaker terminals are proper five-way binding posts rather than the spring clips its price bracket usually got.

Soft Clipping

Soft Clipping is the other NAD idea worth knowing about. When an amplifier is pushed past its limit the waveform normally squares off, which is both audibly nasty and hard on tweeters. NAD’s circuit rounds that limit instead, so the sound compresses rather than tearing. On a 25-watt amplifier asked to fill a room, that is not a specification — it is the difference between a good evening and a blown tweeter.

The Rest of the Feature Set

The rest is sensibly done. The moving-magnet phono stage is a real one on gold-flashed jacks, quoted at 75 dB signal-to-noise with RIAA accuracy inside half a decibel, which is a better phono input than most of what was sold alongside it. There are line inputs for tuner, CD, video and auxiliary, a tape loop, and pre-out and main-in jacks that let you keep the preamp and tuner while adding a bigger power amplifier later. Bass and treble run to plus or minus 10 dB and 7 dB respectively, there is a loudness contour, and a fixed infrasonic filter rolls off below 15 Hz to stop warped records wasting cone excursion. Speaker A and B outputs, and a headphone jack.

Condition

Cosmetically this example is graded Very Good, showing the light marks a well-kept component of its age carries. It has been thoroughly inspected and tested to confirm full functionality.

Twenty-five honest watts that behave like far more when the music asks, a phono stage worth using, and the pre-out that means it need never be the last amplifier you own.

We service NAD, too. Bring us your own NAD receivers, amplifiers, preamps, CD players, tuners and turntables for repair, servicing or restoration, with a 90-day warranty on the work. See our Audio Service page

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.
