NAD - C 359s Integrated Amplifier
Full Details
Experience the Sonic Virtue and Tactile Feel of a Traditionally Minded Integrated Amplifier That Gives You Room to Expand: 70Wpc NAD C 359S Focuses on Audiophile Performance and Flexible Connectivity, Offers BluOS Streaming, MM Phonostage, and More
The NAD C 359S integrated amplifier is simple by design. No fancy display, no visual distractions, no unnecessary complexity. Just solid push-buttons, rotary knobs, and the physical feel of a no-fuss integrated amplifier concentrated on sound and connectivity. Or what matters most.
Engineered for usability, reliability, and ease, the Roon-ready C 359S features the company's classic Class AB architecture along with a four-layer PCB layout; dedicated circuitry for power supply, signal processing, and power amplification; and optimized grounding and signal routing. Its high-current switched-mode power supply provides stable output, low ripple, and excellent transient response. An honestly rated 70Wpc output ensures high-end control and drive of your speakers.
While the 19.6-pound C 359S harbors traditional audiophile features, it also claims modern touches that allow you to expand your system as you wish. An HDMI eARC input, optical digital input, Ethernet port, subwoofer output with optional fixed high-pass filter, and BluOS streaming ecosystem invite you to mix and match sources. Not to mention tap into 24-bit/192kHz high-res audio from more than 20 leading services. And Bluetooth aptX HD for wireless listening.
You also get a front-panel headphone output, two pairs of line-level inputs, and treble, bass, and balance tone controls. And the choice to command it all via the supplied remote or the intuitive app. So whether you currently have a pair of speakers and a CD player, or already own or plan to get a subwoofer, outboard streamer, turntable, and/or tape deck, you're in good hands with the 4.0 x 17.25 x 15.25-inch (HWD) C 359S. 100% Music Direct Satisfaction Guaranteed.
