{"product_id":"sa20-integrated-amplifier","title":"SA20 Integrated Amplifier","description":"\u003cp\u003eThere are two frequent problems with hi-fi amplifiers. Class A, the traditional audiophile’s choice, uses a single power supply constantly running at full capacity, even when there’s no signal coming through. Great for reproducing those subtle details at low levels however struggles to provide extreme power when needed.\u003c\/p\u003e\n\u003cp\u003eClass A\/B, the most common amp class, switches between the two internal amplifiers, one for each half of the waveform. Far more efficient but often a recipe for crossover distortion, since those low-level details we crave can get lost within any mis-match between the two switching over.\u003c\/p\u003e\n\u003cp\u003eClass G is essentially a hybrid amplifier, utilising Class A specifically for low-level signals, but when required switching in an additional power supply to power those larger sections of the waveform.\u003c\/p\u003e\n\u003cp\u003eTo find out more about Class G in simple to understand terms, \u003cspan style=\"text-decoration: underline;\"\u003e\u003cspan style=\"color: #0000ff;\"\u003e\u003ca href=\"https:\/\/www.arcam.co.uk\/ugc\/tor\/avr850\/Class%20G%20Explained\/Class_G_the_ultimate_amplifier_technology_150714_A.pdf\" target=\"_blank\" title=\"Class G explanation PDF\" style=\"color: #0000ff; text-decoration: underline;\" rel=\"noopener noreferrer\"\u003eclick here\u003c\/a\u003e\u003c\/span\u003e\u003c\/span\u003e to download the PDF.\u003c\/p\u003e","brand":"ARCAM","offers":[{"title":"Default Title","offer_id":44627635372324,"sku":"","price":2495.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/6146\/3588\/products\/sa20-integrated-amplifier-amplifiers-arcam-460660.jpg?v=1676969667","url":"https:\/\/brisbanehifi.com.au\/el\/products\/sa20-integrated-amplifier","provider":"Brisbane HiFi","version":"1.0","type":"link"}
