In the early 1990s, the Compact Disc was all the rage, and vinyl records were being executed en masse. Thirty years later, and oh, how our tables have turned. Mint first pressings of tenor saxophonist Hank Mobley's 1957 album Hank Mobley (Blue Note BLP 1568), which once could be had for $40, now bring upward of $8000. Each. Vinyl continues to enjoy a global resurgence of popularity, while CD sales have plummeted to all-time lows.

What happened? Apparently, yesterday's pops and ticks are today's "warmth," Record Store Day exclusives, and skyrocketing vinyl values. All things old . . .

With reviews of Wilson's Alexia 2 loudspeaker ($57,900/pair) in the July issue, Constellation's Centaur 500 amplifier ($55,000) in the October issue, and Tidal's Akira loudspeaker ($215,000/pair) in the November issue, my system's been inhaling some rarefied air the past few months. Accordingly, I felt I should live with some components priced within the reach of real-world audiophiles. As it happened, I was finishing up my review of the Constellation amplifier when MoFi Distribution's Lionel Goodfield e-mailed me, asking if I'd like to review the new Diamond 11.2 loudspeaker from the venerable British brand Wharfedale.
