Really great. Not great in context or comparison; in and of itself. It’s almost laughably dynamic, making many amps we think of as dynamic sound a little flat and boring by comparison. It extends that dynamic contrast from the quietest level to getting on for PA levels.  \u003ca href=\"https:\/\/www.hifiplus.com\/articles\/audio-research-reference-160-s-stereo-valve-power-amplifier\/\" title=\"AUDIO RESEARCH REFERENCE 160 S STEREO VALVE POWER AMPLIFIER\" target=\"_blank\"\u003e\u003cstrong\u003emore...\u003c\/strong\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e","brand":"Audio Research","offers":[{"title":"Default Title","offer_id":32406198321234,"sku":"ARREF160S","price":60000.0,"currency_code":"NZD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0225\/9777\/products\/Audio-Research-Reference-160S-Stereo-Amplifier-front.jpg?v=1655851774","url":"https:\/\/soundline.co.nz\/en-int\/products\/reference-160-s-stereo-amplifier","provider":"Soundline Audio Online NZ","version":"1.0","type":"link"}
