The question \"Why?\" Why do all conventional amplifiers have to battle with cross-zero distortions? Why are there no truly satisfying solutions to fight the contaminations of the public mains system? Why does one allow that electronic components resonate and thus distort the sound? And last but not least: Why do amplifiers all look alike? Questions which are still open and which served us as the starting point of likely one of the most ambitious projects in the history of amplification technologies: the XA PRE.\u003cbr\u003e\u003cbr\u003e\n\nOverview:-\u003cbr\u003e\u003cbr\u003e\n\n•5 x 2300 mAh battery power supply\u003cbr\u003e\n•48-step electronic volume control (1.5 steps)\u003cbr\u003e\n•DC-Flow circuitry (patent pend.)\u003cbr\u003e\n•'Zero feedback' circuit design\u003cbr\u003e\n•LC filter stages for primary \u0026amp; secondary voltages\u003cbr\u003e\n•Line inputs: 5 x XLR\u003cbr\u003e\n•Line outputs: 2 x XLR Pre-Out\u003cbr\u003e\n•IR remote control\u003cbr\u003e\n•Individualised front parts: silver\/black anodized, lacquered, veneered\u003cbr\u003e\n•2-part aluminium cast chassis (42.5 kg)\u003cbr\u003e\u003cbr\u003e\n\nElectronic Circuitry:-\u003cbr\u003e\u003cbr\u003e\n\nDC-Flow audio circuit (patent pend.) yes\u003cbr\u003e \nElectronic volume control switch\u003cbr\u003e\n (patent pend.) 48 steps (1.5 dB each) \u003cbr\u003e\nSingle ended pure Class A output stage yes \u003cbr\u003e\nZero feedback yes \u003cbr\u003e\nFilter capacitors - \u003cbr\u003e\nPrimary DC-offset filter - \u003cbr\u003e\nPrimary and secondary LC filter stage - \u003cbr\u003e\nActive electronic voltage regulation secondary - \u003cbr\u003e\u003cbr\u003e\n\nInputs \/ outputs:-\u003cbr\u003e\u003cbr\u003e\n\nSymmetrical inputs 5 \u003cbr\u003e\nSymmetrical outputs 2 \u003cbr\u003e\nInput impedance 10 kOhm \u003cbr\u003e\nTrigger (DC voltage) 2 x 12V output \u003cbr\u003e\u003cbr\u003e\n\nChassis and Finishes:-\u003cbr\u003e\u003cbr\u003e\n\nOuter unibody aluminium chassis\u003cbr\u003e\n with heatsinks 18.5 kg \u003cbr\u003e\nInner unibody aluminium core 10.5 kg\u003cbr\u003e \nChassis black powder coated\u003cbr\u003e \nUpper and lower brackets black or silver anodized \u003cbr\u003e\nHandles black or silver anodized \u003cbr\u003e\nCommand bar black or silver anodized \u003cbr\u003e\nFrontpanel -black or silver anodized\u003cbr\u003e\n -wooden veener\u003cbr\u003e\n -high gloss lacquer finish \u003cbr\u003e\u003cbr\u003e\n\nDimensions \/ Weight:-\u003cbr\u003e\u003cbr\u003e\n\nWidth x Height x Depth 484.5 x 190.0 x 486.0 mm \u003cbr\u003e\nWeight 41.0 kg \u003cbr\u003e\u003cbr\u003e\n\nIndividualisation:-\u003cbr\u003e\u003cbr\u003e\n\nFront:\u003cbr\u003e\n\n Alu Black\u003cbr\u003e\n Alu Silver\u003cbr\u003e\n Sapphire Burma Blue*\u003cbr\u003e\n Smaragd Pearl Green*\u003cbr\u003e\n Saona Beach Cream*\u003cbr\u003e\n Light Topaz Blue*\u003cbr\u003e\n Light Amber Bronze*\u003cbr\u003e\n Stealth Nocturne Grey*\u003cbr\u003e\n Shiny Citrine Orange*\u003cbr\u003e\n Tiger Rosewood*\u003cbr\u003e\n Akoya Pearl White*\u003cbr\u003e\n Ruby Brilliant Red*\u003cbr\u003e\n Turmaline Vivid Black*\u003cbr\u003e\u003cbr\u003e\n \nMetal Parts:\u003cbr\u003e\n\n Alu Black\u003cbr\u003e\n Alu Silver\u003cbr\u003e\u003cbr\u003e\n\n *optional customization  \n ","brand":"Avantgarde","offers":[{"title":"Default Title","offer_id":57415146701132,"sku":"AVANTGARDEXAPRE","price":12500.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1053\/6891\/2204\/files\/Avant-XA-pre-silver.jpg?v=1777554270","url":"https:\/\/www.stoneaudio.co.uk\/products\/avantgarde-xa-pre-xapre-pre-amplifier","provider":"Stone Audio","version":"1.0","type":"link"}
