It is celebrated for its innovative engineering and has become a sought-after classic among hi-fi enthusiasts and collectors.\u003c\/p\u003e \u003cp\u003eThis amplifier is recognised for delivering a clear, natural sound with exceptionally low distortion. Its performance is underpinned by the revolutionary \"Current Dumping\" circuit, a patented design that utilises a feedforward loop.\u003c\/p\u003e \u003cp\u003eThe \"Current Dumping\" topology employs a precise low-power Class A stage to manage the audio signal, while a higher-power section provides the necessary output for demanding signals. This approach effectively minimised crossover distortion, a common issue in amplifiers of the period, and ensured stable operation with various speaker loads.\u003c\/p\u003e \u003cp\u003e- Power Output: 100 watts per channel into 8 ohms\u003cbr\u003e- Total Harmonic Distortion: Less than 0.01% at 1 kHz\u003cbr\u003e- Signal-to-Noise Ratio: 95 dB\u003cbr\u003e- Input: 4-pin DIN\u003cbr\u003e- Speaker Terminals: Spring-loaded\u003cbr\u003e- Weight: 9 kg\u003c\/p\u003e","brand":"Why Buy New","offers":[{"title":"Default Title","offer_id":64631966237049,"sku":"Q405PA-C3-GY","price":219.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0749\/8409\/6055\/files\/abbe5716-59ef-4e88-a08b-3bbb31480116.jpg?v=1789742915","url":"https:\/\/whybuynew.co.uk\/products\/quad-405-power-amplifier-3","provider":"Why Buy New","version":"1.0","type":"link"}
