NAD C 298
NAD has introduced some of the most innovative amplifier technology in its nearly 50 year history, starting with the 3020 on through such cutting edge models as the 2200, the 208, and the M2. Now we are making the amazing new Eigentakt™ (self-clocking) technology, recently introduced to the world in the EISA Award winning Masters M33, available to a wider audience with the very affordable C 298. We are thrilled to provide this unprecedented level of performance. In short, a perfect companion for the C 658 BluOS Streaming DAC pre-amp.
Powerful. Efficient. Eigentakt™
Amazing Flexibility
The C 298 may be a basic Power Amp, but we have carefully thought through all the use cases typically encountered to create a rich feature content. Selectable balanced inputs make the C 298 a natural for studio use or connection to High End Preamps and Processors. These inputs include a trim control useful for matching to other components. A line out allows further addition of power on the same channel for additional speakers or subwoofers. Auto-sense with selectable threshold is perfect for automating complex systems or hiding the amp out of sight in a cabinet. We even include a Ground Lug that can be very useful for eliminating ground loops and noise in complex multi-unit systems. Added to all this connectivity is a Bridge Switch that turns the C 298 into an amazingly powerful Monobloc Amplifier. Start with one and add a second C 298 later when you upgrade your speakers.
Getting the Basics Right
It is surprising how many seemingly advanced products in the market today often miss many of the most basic requirements for satisfying performance. Low noise circuits, accurate channel balance, proper input and output impedance characteristics, high overload margins and stability with difficult speaker loads. NAD starts by getting these things precisely right and advances from there. Our line inputs, both Balanced and Single-ended, can accommodate all kinds of analog source components by offering ideal input impedance characteristics with linear ultra-low-noise buffer amplifiers to prevent any sonic degradation caused by inappropriate loading of the source device. These are all details you can hear.
Sophisticated Power
NAD has moved away from the old fashioned and very power hungry linear power supplies and Class AB output stages that waste nearly half of the energy consumed producing heat rather than sound. Instead we have developed even better performing circuits based on switch mode power supplies and Class D output stages. Once thought to be inferior to traditional topologies, NAD’s advanced work in this area has created some of the best performing amplifiers regardless of basic design principle. These new designs are very linear over a wide bandwidth and provide consistent performance into all speaker loads, providing a dramatic advance over previous models.
The generously dimensioned power supply easily allows for 185 watts continuous and over 570 watts instantaneous power for short term musical transients. Innovative Asymmetrical Power-Drive fully utilizes every last watt available with its vast reserves of dynamic power available to accurately reproduce musical transients without distortion or compression. It can operate with any AC mains voltage from 100v to 240v and provides pure DC power to all the various stages of the C 298. This highly efficient supply also provides near perfect regulation of voltage across a wide range of conditions and provides a solid noise-free foundation for the amplifying stages.
Purifi ‘Eigentakt’ Amplifier Technology
Purifi is a Danish technology company that has brought together several of the industry’s leading engineers to apply advanced mathematical modelling to solve the last remaining limitations of audio amplifiers. While there are many good sounding amplifiers on the market today, Purifi has taken a fresh look at every aspect of amplifier performance and found many seemingly small non-linearities that can make a dramatic difference in the overall sound. This return to first principles has resulted in a stunningly simple approach to some remarkably complex problems. With features and technology unmatched by other amplifiers in its class, the C 298 amplifier is an easy upgrade for any system and a surprising partner for the most sophisticated and advanced loudspeakers on the market.

NAD C 298 — compact, high‑power Class D with surprising musicality
The NAD C 298 channels Purifi Eigentakt Class‑D modules into a modest, cool‑running chassis to deliver startling headroom and snap. Reviewers including Mark Craven and Evan McCosham highlight its combination of visceral dynamics, tight controlled bass and an open, well‑layered soundstage. The C 298 excels at transient detail and imaging while remaining largely neutral and uncoloured; it’s voiced for clarity rather than warmth. Build and ergonomics are purposeful: a conservative matte finish, balanced XLR and RCA inputs, bridge/mono option and auto‑on/trigger functions make it easy to integrate. Ideal for listeners who want a high‑power, low‑noise amplifier to drive demanding speakers or to use as bridged monoblocks. For its feature set and performance the C 298 is repeatedly judged a standout value by multiple reviewers.
Pros
- Exceptional dynamics and headroom — fast, punchy transients and the ability to drive low‑impedance loads without strain.
- Outstanding imaging and soundstage depth — precise left/right placement and layered front‑to‑back perspective.
- Clean, low‑distortion Purifi Eigentakt implementation with flexible connectivity (XLR/RCA, bridge/mono, auto‑on) and genuine power (185Wpc stereo; 620W bridged).
&
Cons
- Slightly less bass weight compared with some higher‑priced reference amps — excellent grip and speed but a touch lighter in perceived heft.
- Upper treble is a little restrained/‘polite’ relative to very vivid solid‑state designs — a musical, low‑distortion balance that may not suit those seeking extra sparkle.

Dynamics
93/100
Reviewers consistently praised the C 298's slam, headroom and control: quoted damping factor >800, peak current >25 A and very high IHF dynamic power (260W–570W stereo; up to 1100W bridged) back the claims. Multiple reviews note 'astonishing sense of dynamism', 'enormous power', 'drives difficult loads' and 'in-the-room' transient snap, and reviewers highlighted stable performance into low impedances and bridge mode for even greater authority. These factors justify a top-tier dynamics score for a Class-D amp in this power class.
Soundstage Imaging
91/100
Imaging and soundstaging receive strong praise: comments include exceptional left-right placement, remarkable depth and layering, images 'locked firmly in place' and 'holographic' presentation. Multiple reviewers found the C 298 produced more precise spatial definition than pricier rivals in some respects, making it one of the unit's standout strengths. It maintains spatial stability even when delivering high power.

Build Quality
86/100
Build is described as solid, modest and fit-for-purpose rather than extravagant: compact 11.2kg chassis, low heat output, clean rear-panel layout with XLR/RCA, triggers and bridge switch. Reviewers note serviceable hardware and thoughtful features (fixed/variable gain, auto-sense, bridge/mono) but also that the finish and component extravagance are appropriate to its mid-price positioning rather than flagship-level. Bridge/mono capability and tidy thermal design are positives for reliability and versatility.
Value for Money
93/100
At NAD's stated street price (~$1,999) reviewers repeatedly call the C 298 'unquestionable value', 'serious value' and 'magnificent at this price', citing performance that rivals much more expensive amps (examples include comparisons with a Bryston that costs roughly twice as much). The combination of 185 Wpc stereo (340 W into 4Ω), 620 W bridged mono capability, very low distortion and extensive features makes its price-to-performance proposition compelling and well-justified in its segment.
