The Wilson Audio Specialties Alexx V ($135,000–$151,000/pair) is the biggest, heaviest, most expensive loudspeaker I've had in my listening room. It replaces the original Alexx in Wilson's lineup; Michael Fremer reviewed the earlier Alexx, bought it, and owned it until replacing it recently with the Wilson Chronosonic XVX.

Even though I'm the editor of Stereophile, I sometimes struggle to get my audio system to play. It's a little bit embarrassing. Just last night, I put on a record and there was no sound. I figured out the problem immediately: I'd forgotten to turn on the amplifiers. But the reason isn't always so obvious.

Two new reissues in Blue Note's Classic Vinyl series—Grant Green's Idle Moments and Kenny Burrell's Midnight Blue—capture peaks of jazz guitar's possibilities at a juncture when modernism was primed for a shift to something else. Both albums were recorded in 1963; both sport "the Blue Note sound," which engineer Rudy Van Gelder had refined to its high point. But the two albums lay out very different musical paths.
