In August 2020, the NAD M33 was released, a brand new high-end \nstreaming integrated amplifier that uses the innovative new Purifi EigentaktTM technology \nfor the first time worldwide and was promptly awarded the EISA Award as best \n\"Smart Amplifier 2020\/21\".\u003cbr\u003eWith the new C 298 stereo power amplifier, NAD aims to \nmake the unique Purifi EigentaktTM amplifier technology accessible to a wider \naudience. It is the perfect companion for the BluOS streaming preamplifier C 658 \nand impresses with enormous power.\u003cbr\u003ePurifi is a Danish technology company where \nsome leading developers in the hi-fi industry aim to identify and eliminate the \nlast remaining weaknesses in digital amplifier technology. The current state of \ntheir work resulted in the Purifi EigentaktTM amplifier, which NAD is the first \ncompany to license and has so far exclusively used in the BluOS streaming \namplifier M33.\u003cbr\u003eThe Purifi EigentaktTM technology impresses with extremely low \nintermodulation distortion, a particularly low total harmonic distortion of only \n0.005% over the entire frequency range and the complete power bandwidth, as \nwell as minimal inherent noise.\u003cbr\u003ePivotal for the development of EigentaktTM \ntechnology was the realization that a memory effect occurs in the components in \nthe output filter of the amplifier. This phenomenon, known as hysteresis, \nevidently leads to the known sonic degradation of conventional digital \namplifiers. By modifying the output stage and using the clever algorithms of \nEigentakt technology, Purifi succeeded in significantly reducing hysteresis \neffects. Another advantage of the EigentaktTM power amplifiers is that they are \nabsolutely immune to changing speaker loads. Their extremely low output \nimpedance also leads to a very high damping factor, which results in an \nabsolutely clean and controlled bass reproduction.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eEnormous Power Reserves\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eInstead of old-fashioned linear power supplies and \nClass AB amplifiers, which convert almost half of the required energy into heat \ninstead of power, NAD only uses switching power supplies and Class D power \namplifiers in its current amplifiers. This design works very linearly over a wide \nrange and offers consistent performance to all speaker loads, which represents a \ndramatic improvement over earlier techniques.\u003cbr\u003eThe generously dimensioned power \nsupply of the C 298 allows the power amplifiers an enormous continuous power of 2 \nx 340 watts (into 4 Ω) and up to 2 x 570 watts of impulse power (into 2 Ω). The \ninnovative asymmetric PowerDrive technology uses every available watt to provide \nenormous dynamic reserves to reproduce music precisely without distortion or \ncompression. In addition, the highly efficient power supply impresses with \nnearly perfect voltage regulation over its entire operating range, ensuring a \nsolid, noise-free power supply for the amplifier stages.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eHybridDigitalTM Purifi EigentaktTM \nAmplifier\u003cbr\u003eContinuous output power: 2 x 185 W into 8 Ω, 2 x 340 W into 4 \nΩ\u003cbr\u003eImpulse power: 2 x 260 W \/ 2 x 490 W \/ 2 x 570 W (into 8\/4\/2 \nΩ)\u003cbr\u003eImpulse power in bridge mode: 1,000 W into 8 Ω, 1,100 W into 4 \nΩ\u003cbr\u003eBalanced XLR inputs\u003cbr\u003eGold-plated RCA inputs\u003cbr\u003eAdjustable input \nlevel\u003cbr\u003eHigh-level output for looping through the audio signal to other power \namplifiers\u003cbr\u003eInputs and outputs for 12 V trigger signals\u003cbr\u003eAdjustable sensitivity \nfor automatic power-on\u003cbr\u003eInputs and outputs for IR\u003cbr\u003eGround terminal\u003cbr\u003eSeparate \npower cable\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eFlexible \nApplication Possibilities\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe C 298 may at first glance appear to be a simple \nstereo power amplifier, but NAD engineers have carefully considered all \napplications to develop a power amplifier that is as universally applicable as \npossible. For example, the C 298 has balanced inputs, making it suitable for \nprofessional studio use and connection to high-end preamplifiers and processors. \nThanks to its variable input sensitivity, the C 298 can be perfectly integrated \ninto constellations with other amplifiers or active speakers and subwoofers – the \nrequired high-level preamplifier output is already part of the equipment package. \nAn auto power-on function with adjustable sensitivity simplifies the operation of \ncomplex systems and allows for hidden operation of the amplifier. The ground \nterminal prevents ground loops and hum disturbances in audio systems with \nmultiple amplifiers. And finally, if required, the C 298 can also be operated in \nbridge mode, which turns it into an astonishingly powerful monoblock amplifier. \nStart with one C 298 and add a second later when you upgrade your speaker \nsystem.\u003cbr\u003eFundamental Requirements\u003cbr\u003eIt is astonishing how many seemingly advanced \nproducts on the market today often do not even meet the basic requirements for \nreliable and good-sounding operation. NAD, on the other hand, understands the \nimportance of low-noise circuitry, precise channel balance, correct input and \noutput impedance characteristics, large headroom, and stable amplification even \nwith difficult speaker loads. NAD's engineers consider these fundamental aspects \nin their work and continuously develop them further.\u003cbr\u003eFor example, the high-level \ninputs of the C 298 – whether the balanced XLR or the conventional RCA jacks – \nare suitable for all types of analog audio sources, as they feature an ideal \ninput impedance with linear, extremely low-noise buffer amplifiers to prevent \nsonic degradation due to impedance mismatch.
