NAD C298 Poweramp
Redefining the State of the Art with Purifi Technology
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.
Reviews
Absolute Sound awards NAD C298 Amplifier of the Year
"NAD’s C298 is built around a new Class D output stage called “Eigentakt” (“self-clocking”) that represents a significant technical advance in switching amplification. The C298 is rated at 185Wpc into 8 ohms and 340Wpc into 4, and is packed with features, including balanced and single-ended inputs and line outputs for daisy-chaining multiple amplifiers, a bridging function for monaural operation, and an auto-on feature when a signal is detected. The C298 sounds like a powerhouse, with effortless dynamics, a tight and solid bottom end, and a general sense of ease in complex passages. The C298 goes very low in the bass, has a nice sense of midbass heft and weight, and delivers outstanding dynamic punch. It also has an unusually satisfying ability to convey music’s rhythmic flow and forward propulsion. The midrange has nice presence, with a bit of forwardness from the upper mids to the lower treble imparting a lively quality. The C298 is a lot of amplifier for the money, and our choice for Solid-State Power Amplifier of the Year"

NAD C298 gets Stereophile Recommended Products Award
"An affordably priced, powerful—185Wpc into 8 ohms. 340Wpc into 4 ohms—utilitarian-looking, class-D stereo amplifier based on the Purifi-Eigentakt output modules used in NAD's more expensive M33 and M28. The C 298 features balanced and single-ended inputs, variable gain, and can also be operated in bridged-mono mode. KR found that a pair of bridged-mono NADs offered explosive dynamics without breaking a sweat—JA measured the clipping power into 8 ohms in this mode as 980W! "The NAD C 298 is a transparent, uncolored, powerful stereo power amplifier," concluded KR, adding that even in stereo mode it can easily drive most speakers "to levels that exceed domestic tranquility." Measuring man JA commented that the C 298 continues NAD's tradition for conservative and competent engineering but "sets a new standard for combining very high power with supremely low distortion."
