I owned a pair of classic Infinity Reference 60's for 18 years and they never skipped a beat. The Ref 60's were the top of the range in the Reference series & used an Emit-r tweeter & IMG dynamic mid and bass drivers. Although these speakers only cost $2kAUD way back when, with Infinity's ongoing development and policy of filtering down technology, the Ref 60's still sounded well balanced, fast and decent bass. And Cary Christie's usually beautiful cabinetry made them nice pieces of furniture. That value equation made them hard to sell. I eventually upgraded to a pair of Renaissance 90's which I owned briefly. I now own a pair of Magico S5's which are the first speaker which brought back the same sense of awe and engagement as the Infinity IRS series. I suspect I may keep them a long while..than is until an M-Project-inspired replacement comes along one day ;)
