The HPA4 delivers power, audio fidelity, speed and accuracy over an utterly silent background.\u003c\/p\u003e\n\u003ch2\u003eTHE ULTIMATE LINE AMPLIFIER\u003c\/h2\u003e\n\u003cp\u003eThe THX-888 amplifier is driven by a Benchmark line amplifier that features relay gain control, relay input selection, and relay muting. The line amplifier incorporates the finest gold-contact relays available. The gain control has 256 steps in 0.5 dB increments. It also features a balance control. Relay closures are precisely timed to deliver silky-smooth volume changes. No other relay gain control offers this level of precision and performance. The HPA4 includes 4 independent 256-step attenuators: two for the L\u0026amp;R headphone outputs, and two for the L\u0026amp;R line outputs. To make this all happen, the HPA4 includes a total of 64 precision relays.\u003c\/p\u003e\n\u003ch2\u003e100% ANALOG SIGNAL PATH\u003c\/h2\u003e\n\u003cp\u003eThe HPA4 is 100% analog. It is designed to be driven from an external D\/A converter or an external analog source. The HPA4 is designed to provide the ultimate analog signal path between inputs and outputs. The HPA4 eclipses the performance of typical high-end preamplifiers by achieving much lower noise and distortion.\u003c\/p\u003e\n\u003ch2\u003eHIGH VOLTAGE, HIGH CURRENT AND HIGH POWER\u003c\/h2\u003e\n\u003cp\u003eThe THX-888 amplifier can cleanly deliver high voltage into low-sensitivity high-impedance headphones and it can cleanly deliver high power and current into low-impedance headphones. The HPA4 delivers 11.9 Vrms into 300 Ohms and 6 Watts into 16 Ohms. Given these extreme capabilities, Benchmark has incorporated several protection systems to protect expensive headphones and the amplifier itself. These include DC detection, short-circuit detection, over-current protection, over-voltage protection, and thermal protection.\u003c\/p\u003e\n\u003ch2\u003eSPEED AND PRECISION\u003c\/h2\u003e\n\u003cp\u003eThe bandwidth of the HPA4 extends from 0.01 Hz to over 500 kHz. This means that the HPA4 delivers very precise amplitude and phase accuracy over the entire audio bandwidth. Wave shapes are accurately reproduced, and the entire spectrum is delivered with precise timing. The HPA4 will deliver musical overtones with life-like accuracy. This means that musical instruments are rendered without changing their sonic character.\u003c\/p\u003e\n\u003ch2\u003eBALANCED AND UNBALANCED I\/O\u003c\/h2\u003e\n\u003cp\u003eThe headphone output of the THX-888 amplifier features a 1\/4\" TRS and a 4-pin XLR. Both outputs deliver the full performance of the HPA4. However, we recommend the XLR4 due to its lower contact resistance. The HPA4 features two balanced stereo inputs and two unbalanced stereo inputs. The line amplifier provides one balanced stereo output, one balanced mono sum, and one unbalanced stereo output.\u003c\/p\u003e\n\u003ch2\u003eSYSTEM INTEGRATION\u003c\/h2\u003e\n\u003cp\u003eThe HPA4 includes IR remote control and can be operated using the optional Benchmark remote. The HPA4 is designed to work with the Benchmark DAC2 and DAC3 converters but may be driven from any high-end D\/A converter. When paired with a Benchmark DAC, a single remote control will operate both units.\u003cbr\u003e\u003cbr\u003eThe HPA4 is the perfect complement to the Benchmark AHB2. It may be the only preamplifier or line amplifier that exceeds the signal to noise ratio of the ultra-quiet AHB2. This means that the HPA4 will extract the full performance of the AHB2. In contrast, other preamplifiers limit the system noise performance because they cannot match the SNR performance of the AHB2. The HPA4 is the only line amplifier\/preamplifier that we recommend inserting between a DAC and the AHB2. The HPA4 can be inserted between a Benchmark DAC3 and AHB2 without degrading the system noise performance. With the HPA4 inserted, the DAC3's 32-bit digital gain control is replaced by the HPA4's more-resolving fully-analog relay gain control.\u003cbr\u003e\u003cbr\u003eTwo bidirectional 12V trigger ports can be used to link the HPA4 with external D\/A converters and power amplifiers. The trigger signal controls the power-up and power-down sequencing of the entire audio system. The trigger ports are compatible with most industry-standard trigger input or output ports, but can communicate bidirectionally with other Benchmark products.\u003c\/p\u003e\n\u003ch2\u003eTOUCH SCREEN\u003c\/h2\u003e\n\u003cp\u003eThe touch screen provides easy access to advanced features such as balance control, input level offsets, input names, screen dimming, remote control, and function locking.

You see, there has never before been a component offering such a rich palette of both new and proven technology. Bold statements?

It also has moved away from analog to digital. The C 658 has incorporated these fundamental truths to create an entirely new type of component that combines a Network Streamer, a state-of-the art DAC, and many aspects of the traditional Preamplifier into a single highly cost effective package. And thanks to NAD’s exclusive Modular Design Construction, it will keep pace with the latest technology, not yet introduced, but inevitably coming in the future. In fact, an optional HDMI 4k switcher module is available now allowing the best sound from any of the many HDMI sources available (like game consoles and video STBs). While the C 658 immediately replaces (or adds) your Streamer, DAC, and Preamp, it also adds many new features you may not be aware of, like a Bluetooth aptX HD transmitter to use with your wireless headphones. The highly flexible outputs allow for a true balanced connection to powered speakers or amplifiers. Single-ended connections for amplifiers and subwoofers are also provided and include an adjustable subwoofer crossover executed perfectly in the digital domain. A highly sophisticated MM Phono input is also included along with line inputs for legacy analog components.\u003c\/p\u003e\n\u003ch3\u003eBluOS™ Enabled\u003c\/h3\u003e\n\u003cp\u003eAlso on board is BluOS, the most sophisticated High Res streaming system available. BluOS natively supports over 15 streaming music services and indexing of over 250,000 tracks from local network sources. The C 658 becomes a node in the BluOS ecosystem allowing high res network streaming to 64 zones and control options for iOS, Android, Windows, and Mac OS phones, tablets, and desk top devices. BluOS also supports all major smart home controllers and is available in a wide range of products making it easy to create a whole house audio system with the C 658 at its heart.\u003c\/p\u003e\n\u003ch3\u003eTraditional NAD Performance and Value\u003c\/h3\u003e\n\u003cp\u003eThe C 658 is part of our Classic Series of components which have an enviable reputation for giving Music Lovers more enjoyment for less money. If you want a solid block of hand–crafted aluminum with gold plated accents you’ll need to look elsewhere. If you want state-of-the-art performance and features in a sturdy no-nonsense package then you have the right address.\u003c\/p\u003e\n\u003ch3\u003eHigh Resolution in Every Detail\u003c\/h3\u003e\n\u003cp\u003eMost NAD components have been High Res for 45 years with very wide bandwidth, low distortion, and ultra-low noise. We just never had High Res source material to play. With High Res digital recording and streaming, combined with advanced technology like MQA, record companies are opening their vaults and releasing Studio Master Quality recordings. MQA decoding is available through BluOS Streaming content. The C 658 is pure High Res from input to output and features the ESS Sabre 32bit DAC , one of the best performing DACs on the market today with its 118dB Dynamic Range and incredibly low jitter spec. All preamp functions are executed in the digital domain including the same wide range non-truncating digital volume control used in our Masters Series components. This offers an incredibly short analog signal path that, rather uniquely, is identical for all volume settings. Sophisticated active power supplies provide super clean voltages to all circuits to keep noise and distortion at the edge of measurability.\u003c\/p\u003e\n\u003ch3\u003eMake the Speakers Disappear (It’s Not Magic)\u003c\/h3\u003e\n\u003cp\u003eThe C 658 is also the first NAD stereo component to feature Dirac Live room correction*, the most sophisticated and effective room correction available. Dirac corrects the impulse response of your speakers, in addition to the frequency response of your room, for a truly transparent window into the musical performance. When the room resonances are tamed and the transient response is corrected, the result is magical. You have never heard your speakers sound this invisible or this good!\u003c\/p\u003e\n\u003cp\u003e*Note: The C 658 includes a license for Dirac Live with the option for advanced users to upgrade to a Dirac Live Full Frequency version.\u003c\/p\u003e\n\u003ch3\u003eMaster Quality Authenticated\u003c\/h3\u003e\n\u003cp\u003eMaster Quality Authenticated (MQA) is a revolutionary end-to-end technology built into every BluOS Enabled amplifier to capture and deliver MQA music to your speakers in the purest quality.
