C 298

STEREO POWER AMPLIFIER

The NAD C 298 Stereo Power Amplifier is designed to deliver exceptional clarity and control for high-performance music systems. Built around Purifi Eigentakt™ amplification, it allows loudspeakers to perform with greater precision and ease across a wide range of volumes. The C 298’s performance has earned international recognition from hi-fi and mainstream press, reflecting both its engineering and musical results. Designed to partner naturally with components such as the NAD C 658 BluOS Streaming DAC, the C 298 provides a stable, transparent foundation for advanced two-channel systems.

KEY FEATURES

  • Purifi Eigentakt™ amplifier technology for exceptionally low noise and distortion
  • 185 watts per channel of continuous power into 8 ohms
  • Bridgeable mono mode delivering up to 620 watts into 8 ohms
  • Stable performance with demanding loudspeaker loads
  • Balanced and single-ended analogue inputs for flexible system integration
  • Input level control for precise matching with preamplifiers and sources
  • Line output for daisy chaining additional amplifiers or system expansion
  • Auto turn-on with selectable signal-sensing threshold
  • 12V trigger input and output plus ground lug for use in complex systems
  • Award-winning design recognised by EISA and The Absolute Sound

PRODUCT STORY

Purifi Eigentakt Amplification

The C 298 uses Purifi Eigentakt™ amplifier technology to minimise distortion and noise across the entire audible range. This exceptionally linear behaviour allows fine detail, spatial cues, and dynamic contrasts to emerge naturally from recordings. Loudspeakers are driven with greater precision and control, helping music sound more open and effortless, even at higher playback levels.

Power with Control and Headroom

The C 298 delivers high continuous power with generous dynamic reserves, allowing it to handle demanding musical peaks without strain. Its ability to remain stable with demanding loudspeakers ensures consistent performance across a wide range of designs. Whether reproducing subtle passages or wide dynamic swings, the presentation remains composed and authoritative.

Flexible Stereo or Mono Operation

Designed to adapt as systems evolve, the C 298 can operate as a high-performance stereo power amplifier or be bridged into a powerful monoblock delivering 620 watts into 8 ohms. This flexibility makes it easy to start with a single unit and add a second amplifier later when upgrading loudspeakers or expanding a system. Balanced and single-ended inputs, along with adjustable input levels, allow seamless integration with a wide variety of preamplifiers and sources.

Designed for Real-World Systems

Beyond raw power, the C 298 is engineered for practical system integration. Features such as auto turn-on with selectable threshold, 12V trigger connections, a line output for daisy chaining, and a dedicated ground lug simplify use in complex setups. These details help maintain low noise, reliable operation, and consistent performance in both visible and hidden installations.
