NAD Model 304 (2000)

Name: NAD Model 304
Brand: NAD

A 20-watt integrated amplifier that proved entry-level hi-fi didn't have to sound cheap.

Overview

The NAD Model 304, introduced in 2000, was the budget entry point in NAD's Classic series. The line was built on the idea that modest power ratings and sensible engineering beat inflated specs and gimmicks. Next to the flashy Japanese integrated amps of its day, the 304 looks plain. But it has the same design DNA that made NAD's name in the late 1970s: honest power, smart protection circuitry, and a phono stage that actually works.

Rated at 20 watts per channel into 8 ohms, the Model 304 isn't going to rattle windows or drive power-hungry planar speakers. According to reviewers who lived with it, it delivers clean, workmanlike sound that suits medium-efficiency speakers and casual listening without drawing attention to itself. The Classic Hi-Fi review called it safe, well-built, and entirely without major faults, and an ideal inexpensive entry point into classic hi-fi at a budget price point.

The 304 weighs 5 kg and measures roughly 420 mm wide, so it fits on modest shelving without trouble. Its 20Hz - 20kHz frequency response holds within ±0.5dB across the audible band, and total harmonic distortion is a claimed 0.02%. Those figures were respectable for the price point and are still perfectly listenable today. The signal-to-noise ratio is 80dB (as cited by Classic Hi-Fi, without specifying input weighting), so background hiss stays out of the way at normal listening levels.

Key Features

NAD Power Drive and Soft Clipping

AVLand's documentation confirms the Model 304 carries NAD's Power Drive and Soft Clipping technology, the same circuit philosophy behind the 3020. Power Drive gives the amplifier more current delivery into difficult speaker loads than its 20-watt rating might suggest. Soft Clipping rounds off signal peaks before they turn into harsh distortion. In practice, the 304 stays listenable when pushed toward its limits, which matters more at 20 watts than it does at 100. The implementation is simpler than on NAD's larger models.

Built-In Phono Stage

Many budget amplifiers of the period were dropping phono inputs to save a few cents. The Model 304 kept one. Both hifi-wiki.com and AVLand confirm an internal phono stage, and Audio Database lists the MM input sensitivity at 2.5mV, a standard figure that suits most moving magnet cartridges from the period. Classic Hi-Fi's reviewer described the phono stage as clean, if not spectacular. It won't embarrass a decent turntable, and it won't challenge a dedicated outboard preamp either.

Straightforward Input Selection

The input lineup varies depending on the source. hifi-wiki.com lists Phono, Line, and Tape, while AVLand lists Phono, CD, Aux, and Tape. The discrepancy likely reflects different production runs or market variations, but either way the 304 offers the essential sources without clutter. On the output side, both sources confirm tape out, and hifi-wiki.com additionally lists a preamp out. That lets the 304 drive an external power amplifier should the owner outgrow its built-in 20 watts.

Design Philosophy

The Model 304 is plain to look at. Classic Hi-Fi's reviewer noted that its styling lacks the visual excitement of comparable Japanese amps from the same era - no brushed aluminum facades, no glowing meters, no busy control layouts. Buyers got a clear layout with basic features and no excessive circuitry, in line with NAD's 1980s - 1990s build philosophy of substance over show. The compact construction follows the same approach.

This restraint extends to the feature set. The 304 doesn't try to be a do-everything hub; it does the essentials well and gets out of the way. Reviewers noted a lack of soundstage depth compared to some peers, and the 20-watt output is adequate but not abundant — honest assessments that match the amp's positioning. What the 304 lacks in drama, it makes up for in competence. It's the kind of component that disappears into a system, letting the music take center stage rather than the gear.

Historical Context

Introduced in 2000, the Model 304 arrived at an awkward moment for budget hi-fi. The two-channel integrated amplifier was being squeezed between home theater receivers on one side and the first stirrings of digital streaming on the other. NAD stuck to its roots and built a simple stereo amplifier. It was positioned as an entry-level or budget integrated amp within the NAD Classic line, designed to meet budget hi-fi needs in the early 2000s, for listeners who wanted real sound quality without the complexity or cost of separates.

NAD had spent two decades building a reputation for value-conscious engineering, and the 304 inherited it. For listeners who came of age during the CD era and wanted to try proper hi-fi without a major investment, the Model 304 was a low-stakes entry point. It was meant to pair with decent bookshelf speakers and a modest turntable setup.
