No preamp, no DAC, no streaming — just a clean, reference-grade amp stage waiting for your source.\u003c\/p\u003e\n\u003ch3\u003eStory Behind Bringing Masters-Series Eigentakt to the Classic Lineup\u003c\/h3\u003e\n\u003cp\u003eEigentakt — developed by Purifi's Bruno Putzeys and Lars Risbo — debuted in NAD's Masters M33. The C 298 was the first Classic Series product to receive that same module. NAD manufactures the modules under license and pairs them with its own switch-mode PSU and Asymmetrical PowerDrive — Masters-tier engineering in a Classic Series chassis.\u003c\/p\u003e\n\u003ch3\u003eWhy does it matter? How does it improve your listening?\u003c\/h3\u003e\n\u003cp\u003eEigentakt is widely regarded as the most refined Class D platform commercially available. Distortion stays vanishingly low across the entire output range — and Stereophile measured the C 298 as setting a new standard for combining very high power with supremely low distortion.\u003c\/p\u003e\n\u003cp\u003eContinuous power is 185 W per channel into 8 ohms (22.7 dBW), 340 W into 4 ohms — both channels driven, full audio band, at rated THD. Bridge mode delivers 620 W continuous into 8 ohms (27.9 dBW).\u003c\/p\u003e\n\u003cp\u003eIHF dynamic power reaches 260 W (8 Ω), 490 W (4 Ω), and 570 W (2 Ω) in stereo; 1000 W (8 Ω) and 1100 W (4 Ω) bridged. Peak output current exceeds 25 A into 1 ohm for 1 ms — the headroom that lets the amp handle musical peaks effortlessly.\u003c\/p\u003e\n\u003cp\u003eNAD specifies THD below 0.005% from 1 W to 185 W into both 8 and 4 ohms. SNR exceeds 120 dB at 185 W out. Damping factor over 800. Frequency response is ±0.2 dB from 20 Hz to 20 kHz, -3 dB at 60 kHz.\u003c\/p\u003e\n\u003cp\u003eAsymmetrical PowerDrive is NAD's name for the switch-mode supply topology that uses every watt of available reserves to reproduce transients without distortion or compression. Voltage regulation stays near-perfect across a wide range of conditions, providing a noise-free foundation for the amplifying stages.\u003c\/p\u003e\n\u003ch3\u003eWho is this best for?\u003c\/h3\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/2714.svg\" alt=\"✔️\" width=\"15\"\u003e You're building a high-performance separates system and need a power amp that measures and sounds like reference gear without stepping up to the Masters Series.\u003c\/p\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/2714.svg\" alt=\"✔️\" width=\"15\"\u003e You drive demanding speakers — planar magnetics, electrostatics, low-impedance designs, or large floorstanders that need amplifier headroom.\u003c\/p\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/2714.svg\" alt=\"✔️\" width=\"15\"\u003e You want bridged mono headroom — start with one C 298 in stereo, add a second later for a 620W-per-channel bridged pair.\u003c\/p\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/2714.svg\" alt=\"✔️\" width=\"15\"\u003e You need balanced XLR inputs and variable gain to integrate with high-end preamps that have non-standard output levels.\u003c\/p\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/2714.svg\" alt=\"✔️\" width=\"15\"\u003e You're a custom installer — 12V triggers, IR I\/O, auto turn-on, ground lug, and the slim 4.75\" chassis make rack and cabinet integration clean.\u003c\/p\u003e\n\u003ch3\u003eHow does it connect to your system?\u003c\/h3\u003e\n\u003cp\u003eInputs: one pair of balanced XLR and one pair of single-ended RCA, switch-selectable.

The C 298 is a pure power amp — no preamp, no DAC, no streaming, no phono stage.\u003c\/p\u003e\n\u003ch3\u003eIs the C 298 a good match for my speakers?\u003c\/h3\u003e\n\u003cp\u003eMatching depends on power, sensitivity, and impedance — the right answer depends on your speakers and room. The C 298's 185 W per channel handles a very wide range, including demanding planar magnetic and low-impedance designs. Call us at \u003ca href=\"tel:+18009420220\"\u003e800-942-0220\u003c\/a\u003e and we'll help you dial it in.\u003c\/p\u003e\n\u003ch3\u003eWhat are the differences between Class A, Class A\/B, and Class D amplifiers? Which one is this?\u003c\/h3\u003e\n\u003cp\u003eThe C 298 uses Class D — specifically Purifi Eigentakt. Class A keeps the output transistors fully on (clean, but hot and inefficient). Class A\/B is the traditional analog blend.\u003c\/p\u003e\n\u003cp\u003eClass D switches the output transistors rapidly. Eigentakt is widely regarded as the most refined Class D platform commercially available — combining high efficiency with reference-grade measurements.\u003c\/p\u003e\n\u003ch3\u003eHow do I bridge it to mono?\u003c\/h3\u003e\n\u003cp\u003eFlip the bridge switch on the rear panel. This combines both channels into a single mono output delivering 620 W continuous into 8 Ω. To run a stereo pair of bridged mono C 298s, you need two units (one per channel).\u003c\/p\u003e\n\u003cp\u003eNote: Purifi modules require non-standard bridging — connect speakers between the L+ and R- terminals; never connect subwoofers, switches, or headphone adapters with common ground connections.\u003c\/p\u003e\n\u003ch3\u003eWhat is the variable gain control for?\u003c\/h3\u003e\n\u003cp\u003eThe variable gain knob lets you adjust amplification between 8.5 dB and 28.5 dB in stereo (14.5 dB to 34.5 dB bridged). Useful when integrating with preamps that have unusual output levels, balancing C 298s against other amps in multi-channel systems, or fine-tuning bi-amped speaker setups.\u003c\/p\u003e\n\u003ch3\u003eDoes this have a built-in DAC, preamp, or streaming?\u003c\/h3\u003e\n\u003cp\u003eNo. The C 298 is a pure stereo power amplifier — no DAC, preamp, streaming, or phono stage. You'll need a separate preamp, integrated amp pre-out, or streaming DAC to feed it. This separation lets you upgrade each component independently.\u003c\/p\u003e\n\u003ch3\u003eHow does this compare to the C 268?\u003c\/h3\u003e\n\u003cp\u003eThe C 268 is the entry Classic Series power amp — 80 W stereo \/ 300 W bridged, HybridDigital UcD (Class D). The C 298 is the step up — Purifi Eigentakt (a more refined Class D platform), 185 W stereo \/ 620 W bridged, with better measurements and multiple major industry awards.\u003c\/p\u003e\n\u003ch3\u003eHow does this compare to the Masters M23 V2?\u003c\/h3\u003e\n\u003cp\u003eThe M23 V2 uses second-generation Purifi Eigentakt modules in a Masters Series chassis. The C 298 uses first-generation Eigentakt at 185W stereo \/ 620W bridged, in Classic Series styling — a more attainable entry point to Eigentakt technology.\u003c\/p\u003e\n\u003ch3\u003eCan I bi-amp my speakers with it?\u003c\/h3\u003e\n\u003cp\u003eYes. The line output lets you daisy-chain to a second amplifier. Run the C 298 to the bass drivers and a second amp to the treble — or vice versa. Speakers that support bi-amping have separate binding posts for the bass and treble drivers.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch2\u003eWhat's in the Box\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eNAD C 298 Stereo Power Amplifier\u003c\/li\u003e\n\u003cli\u003eTwo region-specific AC power cords (select the appropriate cord for your region)\u003c\/li\u003e\n\u003cli\u003eQuick Setup Guide\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhy Audio Advisor?\u003c\/h3\u003e\n\u003cdiv class=\"ec-titlebox-text\"\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/1f3b5.svg\" alt=\"music note emoji\" width=\"20\"\u003e \u003cstrong\u003e40+ Years of Expertise\u003c\/strong\u003e — Since 1981, we've helped over a million music lovers find the right gear.\u003c\/p\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/1f504.svg\" alt=\"repeat emoji\" width=\"20\"\u003e \u003cstrong\u003e60-Day Money-Back Guarantee\u003c\/strong\u003e — Take your time.
