I walked into Jay Rein’s Bluebird Music room and was immediately taken by the hard-rocking sound of Led Zeppelin’s “Moby Dick,” reproduced with appropriate drama, impact, and scale. Here we see Rein standing beside Spendor’s new A9 loudspeaker ($7295/pair). Introduced at this year’s Bristol Show, the A9 made its North American debut at SSI 2010, and sounded excellent, driven by Exposure’s new 3010S2 series: 100W monoblocks ($2595/pair), preamp ($1395), and CD player ($2195). The S2 series replaces Exposure’s Classic line and represents a 50% power increase for one-third less money, Rein told me. Van den Hul’s D352 speaker cables and D102 interconnects ($929) tied this impressive system together.
