Developed with the same attention to musical coherence, transparency and refinement, the AMP II-S is a natural partner to the PREAMP II-S, while its performance and versatility allow it to excel at the heart of any high-end audio system. \u003cbr\u003eThe AMP II-S succeeds the acclaimed Classic AMP, introduced in 2015. It preserves the qualities that made its predecessor so successful: natural tonal balance, effortless dynamics and the ability to combine power with refinement. \u003cbr\u003eMore than a decade of additional experience, including the development of Nagra’s HD and Reference electronics, has allowed our engineers to revisit every critical area of the amplifier, from the power supply and input stage to PCB layout, thermal management and mechanical construction. At the heart of the AMP II-S is a new power-supply architecture that provides greater energy reserves and increased voltage headroom. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eNew Linear power supply architecture Massive CNC-machined heatsink that minimizes unwanted vibrations while providing exceptional thermal inertia for highly stable operation\u003c\/li\u003e\n\u003cli\u003eCustom made 800 VA potted transformer provides greater power reserves and exceptionally quiet mechanical operation\u003c\/li\u003e\n\u003cli\u003eOptimized transformers for different mains voltages\u003c\/li\u003e\n\u003cli\u003eTransformer suspension absorbs 99% of vibrations between 50 and 100 Hz to prevent hum noises \u003c\/li\u003e\n\u003cli\u003e2x 120 W rms into 8 Ohms, 10 W of Class A for sound purity\u003c\/li\u003e\n\u003cli\u003eA single pair of MOSFET transistors per channel for transparency Increased rail voltage for greater headroom and improved transient capability\u003c\/li\u003e\n\u003cli\u003eNew input board, derived from Reference AMP, improves left\/right channel separation for more precise imaging and spatial definition\u003c\/li\u003e\n\u003cli\u003eHand-wiring from the input stage to the power amplifier for greater transparency and clarity\u003c\/li\u003e\n\u003cli\u003eNew internal cabling for greater authority, generosity and definition\u003c\/li\u003e\n\u003cli\u003eOptimized PCB layout, rerouted circuitry further improves sonic performance\u003c\/li\u003e\n\u003cli\u003eOptically isolated controls and front panel for lower noise \u003cbr\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications \u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eClass\u003c\/strong\u003e AB\u003cbr\u003e\u003cstrong\u003ePower\u003c\/strong\u003e 120 W rms into 8 Ω Per channel\u003cbr\u003e\u003cstrong\u003eBandwidth \u003c\/strong\u003e\u0026lt;10 Hz to 75 kHz +0 \/ -3 dB\u003cbr\u003e\u003cstrong\u003eCrosstalk\u003c\/strong\u003e \u0026gt; 90 dB\u003cbr\u003e\u003cstrong\u003eSignal-to-noise ratio \u003c\/strong\u003eTypically 110 dB Measured in ASA A\u003cbr\u003e\u003cstrong\u003eTHD\u003c\/strong\u003e+N \u0026lt; 0.05 % @120 W\u003cbr\u003e\u003cstrong\u003eInput impedance\u003c\/strong\u003e \u0026gt;100 kΩ\u003cbr\u003e\u003cstrong\u003eOutput impedance\u003c\/strong\u003e 60 mΩ\u003cbr\u003e\u003cstrong\u003eDimensions\u003c\/strong\u003e L x W x H 461 x 280 x 174 mm (18.15 x 11.02 x 6.85 in) Overall \u003cbr\u003e\u003cstrong\u003eNet weight\u003c\/strong\u003e 24.5 kg \/ 54 lb\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Nagra","offers":[{"title":"Default Title","offer_id":67637597044923,"sku":null,"price":33995.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2788\/2378\/files\/NagraAMPII-SFront-Black600-600.jpg?v=1792030112","url":"https:\/\/audioconnection.com.au\/products\/nagra-series-ii-amp-ii-s-power-amplifier","provider":"Audio Connection","version":"1.0","type":"link"}
