Sorry, This product is no longer available

The Quad II-eighty (pronounced two eighty) power amplifier wont be available until June 2008, but its worth waiting for. The all-tube, monoblock design is expected to cost about £5000 per pair. As its moniker indicates, the II-eighty will deliver 80 watts/channel into 8 ohms. Quad has recently gone back to its roots in amplifier design. After years of turning out well-received solid state models, the company decided to revisit the still-elegant circuit created by its legendary founder, Peter Walker. That circuit was carried over, albeit with vastly updated parts, to a new model line that, until recently, was capped by the modestly powered II-forty. For the new unit, Quad enlisted another legendary designer, journeyman Tim DeParavinici, to boost output and to refine the original circuit. Price is for a pair.
