This exciting entry point to the North Collection is a superb integrated amplifier, showcasing MOON's premium engineering and the latest in audio technology at its best.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Centerpiece\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe MOON 641 combines a preamplifier and power amplifier in one chassis, based on a dual-mono design. It delivers 125 W \/ 8 Ω and 250 W \/ 4 Ω. The MDCA circuit operates outside the signal path, reducing distortion without global feedback, while M-VOL3 provides precise and stable volume control even at low levels. A damping factor of 700, an SNR of 109 dB, and a frequency response of 2 Hz–90 kHz (+0\/–3 dB) ensure precise control for a wide variety of speakers. The 4.3\" color display simplifies daily use and settings management. Designed and assembled in Quebec, the 641 naturally positions itself as the centerpiece of a modern home audio system.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eComprehensive\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe MOON 641 relies on a meticulous internal structure and vertical cooling fins, ensuring excellent thermal and mechanical stability. Ease of use is enhanced by a 4.3\" color display, clear local controls, and MOONLink connectivity, which allows the device to operate effortlessly with other North Collection components. Standby modes also include a low-power mode (2.5 W) for everyday use. The rear panel features line-level inputs, a line output, and clearly structured speaker terminals for neat cabling. The included BRM-1 intelligent remote control enables direct and intuitive control. Whether the 641 is used alone or combined with a separate source, such as the MOON 681, it provides a clear, reliable user experience that seamlessly fits the North Collection design language.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePerformance\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAt the core of the MOON 641, the combination of MDCA and M-VOL3 technologies sets it apart. MDCA reduces noise and distortion, while M-VOL3 ensures excellent channel balance and subtle volume control. The dual-mono topology and robust power supply maintain signal integrity from inputs to speaker terminals. Published performance values—0.003% THD+N @ 125 W and –109 dB channel crosstalk—verify stable performance at real listening levels. The 4.3\" display simplifies settings management. For digital playback and streaming, the MOON 681 is a natural partner, working seamlessly with the 641 via MOONLink. The result is precise, durable performance that faithfully reflects the North Collection identity.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMDCA – MOON Distortion-Cancelling Amplifier\u003cbr\u003eAdvanced MDCA technology that reduces distortion without affecting the actual signal path.\u003c\/li\u003e\n\u003cli\u003eMOON Transistors - MOON's own precisely matched transistors, ensuring excellent performance and reliability.\u003c\/li\u003e\n\u003cli\u003eDual Mono Configuration - Isolated left and right channels with separate power supplies for optimal channel separation, dynamics, and stability.\u003c\/li\u003e\n\u003cli\u003eM-VOL3 – 3rd Generation Electronic Volume Control - Enhanced gain control that provides precise, stable, and quiet volume management.\u003c\/li\u003e\n\u003cli\u003eMOONLink - An intelligent control system between MOON devices, facilitating joint use and synchronization.\u003c\/li\u003e\n\u003cli\u003e4.3\" LCD Color Graphics Display - A clear and modern display that simplifies daily use and settings management.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOutput Power (stereo, 8 Ω) 125 W\u003c\/li\u003e\n\u003cli\u003eOutput Power (stereo, 4 Ω) 250 W\u003c\/li\u003e\n\u003cli\u003eInput Sensitivity 300 mV – 6 V\u003c\/li\u003e\n\u003cli\u003eInput Impedance 22 kΩ\u003c\/li\u003e\n\u003cli\u003eGain 40 dB\u003c\/li\u003e\n\u003cli\u003eFrequency Response 2 Hz – 90 kHz (+0 dB \/ –3 dB)\u003c\/li\u003e\n\u003cli\u003eCrosstalk –109 dB\u003c\/li\u003e\n\u003cli\u003eSignal-to-Noise Ratio 109 dB\u003c\/li\u003e\n\u003cli\u003eTotal Harmonic Distortion + Noise (THD+N @ 1 W) 0.008 %\u003c\/li\u003e\n\u003cli\u003eTotal Harmonic Distortion + Noise (THD+N @ 125 W) 0.003 %\u003c\/li\u003e\n\u003cli\u003eIntermodulation Distortion 0.06 %\u003c\/li\u003e\n\u003cli\u003eDamping factor 700\u003c\/li\u003e\n\u003cli\u003ePower Consumption (Idle) 38 W\u003c\/li\u003e\n\u003cli\u003ePower Consumption (Full Power Standby) 37 W\u003c\/li\u003e\n\u003cli\u003ePower Consumption (Low Power Standby) 2.5 W\u003c\/li\u003e\n\u003cli\u003eShipping Weight 26 kg\u003c\/li\u003e\n\u003cli\u003eDimensions (W × H × D) 48.1 × 10.2 × 46.5 cm\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Moon","offers":[{"title":"Default Title","offer_id":56781322191223,"sku":"641 2-TONE","price":12500.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0989\/5159\/4359\/files\/641-Front-New-Top_1370x590px.png?v=1771745418","url":"https:\/\/hifikaupat.fi\/en\/products\/simaudio-moon-641-north-collection-integroitu-vahvistin","provider":"Hifikaupat.fi ","version":"1.0","type":"link"}
