Built with NAD’s renowned music-first approach to audio architecture and amp design, the C 338 is equipped with the most advanced components commonly found in NAD’s class-leading line of amplifiers. Always starting with the details you can hear and advancing from there, NAD develops low-noise circuitry with the precision and stability to deliver incredible, near-zero distortion sound for the most difficult speakers.

介绍NAD C338

掌握基础知识

C338采用了NAD著名的音乐第一的音频架构和功放设计方法，配备了NAD领先的功放系列中最先进的元件。NAD总是从你能听到的细节入手，并以此为基础，开发出精确而稳定的低噪音电路，为最困难的扬声器提供难以置信的近乎零失真的声音。

HybridDigital^™ Amp Technology

The search for a high-performance Class D solution led NAD to HybridDigital^™, an innovative amplifier technology that uses a variable modulation frequency to bring out the life-like qualities of music, while reducing distortion under every operating condition. This highly optimized design gives phenomenal performance to the C 338 amplifier, both measured and subjective.

混合式数字™功放技术

为了寻找高性能的D类解决方案，NAD采用了HybridDigital™，这是一种创新的放大器技术，它利用可变的调制频率来展现音乐的生命力，同时降低了各种工作条件下的失真。这种高度优化的设计使C338功放无论在测量和主观上都具有惊人的性能。

Efficient Class D Power

NAD has worked tirelessly to create the best performing Class D amplifiers that are energy efficient and produce beautiful sound—not heat—regardless of basic design principles. Using advanced measurements and data, NAD developed the C 338’s highly efficient power supply with a customised Hypex^® UCD output stage to pump out 160 watts continuously and over 300 watts instantaneously to meet the demands of the most dynamic music. This new design is very linear over a wide bandwidth and provides consistent, noise-free performance for the amplifying stages with near perfect regulation of voltage.

D级高效动力

NAD不顾基本的设计原则，不懈地努力创造出性能最好的D类功放，既节能又能产生优美的声音，而不是发热。利用先进的测量和数据，NAD开发出了C 338的高效电源，搭配定制的Hypex® UCD输出级，可连续输出160瓦的功率，瞬间输出超过300瓦的功率，以满足最动感的音乐需求。这种新的设计在宽广的带宽上具有非常线性的特性，为放大级提供了稳定、无噪音的性能，并具有近乎完美的电压调节。

Always Ready for Streaming

The C 338 has Chromecast built-in so you can cast music, tunes, podcasts, and playlists from your favourite apps on your phone, tablet or laptop to your stereo system. Spotify Connect^® lets you discover millions of songs and stream them directly to your C 338 using the Spotify^® app for a rich, wireless music experience. With the added flexibility of Bluetooth^®, your music streaming possibilities are truly limitless with the C 338.

Built-in Phono Stage for Vinyl Listening

Using a MM phono stage and an innovative low-noise circuit path, the C 338 can reproduce the warmth of LPs with accurate RIAA equalization and control the infrasonic noise that is in all recordings, without ever affecting the bass response.

内置唱机舞台，适合听黑胶唱片

C338采用MM唱机级和创新的低噪声电路路径，可以通过精确的RIAA均衡重现LP的温暖，并控制所有录音中的次声波噪声，而不会影响低音响应。

Flexible Connectivity

With a wide array of connections, including a separate headphone amplifier that can drive high-impedance studio monitor headphones, the C 338 is ready for any type of listening. Line inputs can accommodate all kinds of analogue source components, offering ideal input impedance with linear ultra-low noise buffer amplifiers to preserve the musicality of recordings. Also connect a subwoofer with low impedance line outputs and extend the versatility of this budget-friendly, do-it-all amplifier.

灵活的连接方式

Diamond 12.3

The more compact of the Wharfedale DIAMOND 12 series floorstanding options, the DIAMOND 12.3 loses none of the accuracy and musicality of the standmount (bookshelf) options. With enhanced presence and power, the DIAMOND 12.3 is refined and the perfect, affordable floorstanding speaker for 2-channel hi-fi systems, or as the front pair of a seriously impressive home theatre system.

Configured in a 2.5 way system with exception crossover technology, the DIAMOND 12.3 utilises dual 130mm (5”) Klarity^TM drivers for impactful yet refined mid-range and bass frequencies, while the 25mm (1”) dome tweeter delivers open and smoothly extended high frequencies.

Klarity affords focus

NEW Klarity™ cone material, formulated from a blend of Polypropylene and mica adds stiffness to reduce flexing, enabling a lightweight cone with high rigidity, low colouration and lightning-fast response.

Low colour and expression

The Klarity™ cone is fitted with a low-damping surround, thereby achieving both low colouration and expressive dynamics. By simulating many different cone shapes and adding ribs to provide further stiffening, a flat response curve was achieved without resorting to a high-damping surround, thereby striking the ideal balance.

A magnet of forces

A precision-made magnet system with an aluminium compensation ring to minimise the effect of variations in inductance as the voice coil travels. This contributes to an absence of distortion and intermodulation generated by the ‘motor system’.

A voice coil beyond this class

The voice coil is wound on a high-power epoxy/glass fibre bobbin highly unusual in speakers at this price level. This has the advantage of not adding eddy currents and delivering greater power handling than an aluminium bobbin, whilst also being much stiffer than the Kapton type associated with this price-class.

DIAMOND highs

The 25mm dome is made from a woven polyester film with a high-loss coating to deliver open and smoothly extended high frequencies. The magnet system and the front plate have been optimised for wide dispersion and uncompressed behaviour. The front plate is flat and exposes the dome as much as possible; only a very short duct on the front plate balances the acoustic load and improves the SPL (sound pressure level) measurement.

A crossover of style

The crossover network uses an acoustic LKR 24dB topology. This includes air-core inductors of the type more commonly found in high-end speakers, selected because they produce the lowest distortion of all inductor types. As the resistance of the coil is higher than a standard laminated steel or ferrite core inductor, the magnetic structure of the mid/bass driver has been modified to compensate, resulting in fast, clean bass with no distortion from the inductor.

Firm and fair

The DIAMOND 12.1 ’s rear-ported enclosure is precisely sized so that the internal volume works in harmony with the drive unit system to deliver the desired sonic result. A multi-layered sandwich design subdues the identifiable characteristics of the cabinet’s ‘sound’. Even the resonant properties of the glue between the layers was measured to determine the optimum combination.

Brace yourself

Inside the cabinet, Intelligent Spot Bracing connects opposite walls with a specific form of the wood brace to achieve an optimal reduction of cabinet resonance. These braces are precisely modelled by computer simulation to improve upon the commonplace ‘figure of eight’ brace, which may simply transfer resonance from one wall to another.
