It brings together a high resolution network streamer, an ESS Sabre converter and a fully digital preamplifier, all managed through the intuitive BluOS app for multiroom playback and access to the major streaming services.\u003c\/p\u003e\n\u003cp\u003eConnectivity is generous, with moving magnet phono, line, optical and coaxial inputs alongside Gigabit Ethernet, dual band Wi Fi and two way aptX HD Bluetooth. Balanced and single ended preamp outputs, a subwoofer output and a headphone stage round out the analog side, while a pair of MDC expansion slots keep the platform ready for future upgrades.\u003c\/p\u003e\n\u003cp\u003eA standout feature is the included Dirac Live room correction with calibration microphone, which tailors the sound to the listening space for cleaner bass and sharper imaging. The result is a versatile, upgradeable source that keeps a system current for years to come.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"border:1px solid #e2e4e8;border-left:5px solid #5a31f4;border-radius:10px;padding:14px 16px;margin:0 0 16px;background:#f4f5f7\"\u003e\n\u003cdiv style=\"font-weight:800;font-size:.8em;letter-spacing:.08em;text-transform:uppercase;color:#5a31f4;margin-bottom:8px\"\u003eBuyer’s Guide\u003c\/div\u003e\n\u003cul style=\"margin:0;padding-left:20px;line-height:1.7\"\u003e\n\u003cli style=\"margin:0 0 4px;color:#5a31f4\"\u003e\u003ca href=\"\/blogs\/how-to-guides\/nad-c658-used-plain-english-guide\" style=\"color:#e0631a;font-weight:700;text-decoration:none\"\u003ePlain-English Guide: what every feature does\u003c\/a\u003e\u003c\/li\u003e\n\u003cli style=\"margin:0 0 4px;color:#5a31f4\"\u003e\u003ca href=\"\/blogs\/how-to-guides\/nad-c658-used-audiophile-deep-dive\" style=\"color:#e0631a;font-weight:700;text-decoration:none\"\u003eAudiophile Deep Dive: the engineering explained\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003cdetails style=\"margin:0 0 10px\"\u003e\u003csummary style=\"cursor:pointer;font-weight:700\"\u003eSpecs\u003c\/summary\u003e\u003cdiv style=\"padding:8px 2px\"\u003e\u003ctable style=\"width:100%;border-collapse:collapse\"\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee;font-weight:600;width:44%\"\u003eType\u003c\/td\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee\"\u003eBluOS streaming DAC and digital preamplifier\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee;font-weight:600;width:44%\"\u003eDAC\u003c\/td\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee\"\u003eESS Sabre 32-bit; native playback to 24-bit\/192kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee;font-weight:600;width:44%\"\u003eFormats\u003c\/td\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee\"\u003eMQA, FLAC, WAV, AIFF, ALAC, MP3, AAC, WMA, OGG, OPUS; DSD via BluOS app conversion\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee;font-weight:600;width:44%\"\u003eInputs\u003c\/td\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee\"\u003eMM phono, 2 line RCA, 2 coaxial S\/PDIF, 2 optical; Gigabit Ethernet, dual-band Wi-Fi, aptX HD Bluetooth (two-way), dual MDC expansion slots\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee;font-weight:600;width:44%\"\u003eOutputs\u003c\/td\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee\"\u003eBalanced XLR and single-ended RCA preamp outputs, stereo subwoofer output, headphone output\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee;font-weight:600;width:44%\"\u003eStreaming\u003c\/td\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee\"\u003eBluOS multiroom with Spotify, Tidal, Amazon Music, Qobuz, Deezer and more; Dirac Live room correction included\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee;font-weight:600;width:44%\"\u003eDimensions\u003c\/td\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee\"\u003e435 x 100 x 405 mm (W x H x D)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee;font-weight:600;width:44%\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"padding:5px 10px;border-bottom:1px solid #eee\"\u003e10.1 kg (22.3 lb)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003c\/div\u003e\u003c\/details\u003e\n\u003cdetails style=\"margin:0 0 10px\"\u003e\u003csummary style=\"cursor:pointer;font-weight:700\"\u003eWarranty\u003c\/summary\u003e\u003cdiv style=\"padding:8px 2px\"\u003e\u003cp style=\"margin:0\"\u003eSold as an authorized NAD dealer by All Elite Audio.
