A hand-selected ESS SABRE ES9038PRO DAC with NAD’s proprietary implementation delivers micro-detail, tonal nuance, and spatial accuracy without sounding etched or fatiguing. With BluOS onboard, the M66 streams major services, internet radio, and local libraries, while Dirac Live Room Correction helps optimize timing, imaging, and tonal balance in real rooms. Extensive connectivity includes MM\/MC phono, HDMI eARC, AES\/EBU, USB, optical\/coax digital, and XLR\/RCA analogue inputs, plus balanced\/unbalanced outputs, four configurable subwoofer outputs, and a dedicated high-output headphone amplifier. Finished in an all-alloy chassis with a 7-inch color touchscreen and two MDC2 expansion slots, the M66 is designed for long-term ownership and future upgrades.\u003c\/p\u003e \u003cp\u003eThe NAD M66 is part of ListenUp's \u003ca href=\"https:\/\/listenup.com\/collections\/nad-home-audio\" title=\"NAD Music Streamer Collection\"\u003eNAD Music Streamer Collection\u003c\/a\u003e.\u003c\/p\u003e \u003ch4\u003eWhat It's Good At:\u003c\/h4\u003e \u003cul\u003e \u003cli\u003eReference-grade streaming DAC performance with an ESS SABRE ES9038PRO at the core\u003c\/li\u003e \u003cli\u003ePrecision system tuning with Dirac Live Room Correction and multi-subwoofer integration support\u003c\/li\u003e \u003cli\u003eTruly versatile connectivity for modern and legacy sources (HDMI eARC, phono, USB, AES\/EBU, XLR\/RCA)\u003c\/li\u003e \u003cli\u003eClean, low-noise analogue stage with accurate channel balance and wide dynamic range\u003c\/li\u003e \u003cli\u003eFlexible system building with balanced\/unbalanced outputs and four configurable subwoofer outputs\u003c\/li\u003e \u003cli\u003eFuture-ready ownership with two MDC2 expansion slots and a robust all-alloy build\u003c\/li\u003e \u003c\/ul\u003e \u003ch4\u003eNAD M66 Full Specifications:\u003c\/h4\u003e \u003cul\u003e \u003cli\u003e\u003cstrong\u003ePreamplifier Specifications\u003c\/strong\u003e\u003c\/li\u003e \u003cli\u003eTHD (20 Hz – 20 kHz): \u0026lt;0.001% at 2V out\u003c\/li\u003e \u003cli\u003eSignal-to-Noise Ratio: \u0026gt;105 dB (IHF;
