Her first professional recording became a career-defining global hit, changed the culture, and helped make bossa nova a worldwide phenomenon. but there's a dark side to the success of "The Girl From Ipanema," which followed the Brazilian chanteuse until her recent death.

The next time you're preparing to play a record, try doing a little experiment. Once you have the record mounted and spinning but before you lower the stylus into the groove, lower your gaze to just below record level and look for a gap between the platter and the record. It helps if there's a light source or a brightly colored wall behind the platter. You may discover a gap—that very little of the record's playing area is making true contact with the platter mat or (if there is no mat) the platter. Another way to test this is to take a record you don't care much about, put it on the platter, then tap with your finger in the groove area listening for a click as your finger pushes the record down and it contacts the platter surface.

Warps obviously lead to such problems, but even records that appear flat make scant contact with the supporting surface. Turntable and aftermarket accessory designers have recognized this problem for decades.

Something has happened in jazz culture in the new millennium. There is more emphasis on original composition than ever before. There has been remarkably little discussion and analysis of this phenomenon, perhaps because many assume it is a positive development. Jazz, after all, prioritizes originality.

There is a counterargument. It goes like this: Jazz today is vital and dynamic because great players keep popping up, all over the world. Very few of those great players are also great composers. Yet they apparently feel obliged to be. A large proportion of new jazz albums contain all or mostly originals.

What Were Once Vices Are Now Habits—the 1974 album by those San Jose yacht-rock sages the Doobie Brothers—could also describe an audiophile's life.

The journey begins with booze and bong money spent instead on an entry-level turntable and cartridge; it did for me anyway. Then starts the churn, through many components and configurations seeking that elusive, blissful audio fix until finally we find our audio oasis, our own sonic peace, our gearhead nirvana. We achieve a system that satisfies our listening indulgences, whether it be based on streaming or spinning, class-D or tubes, with Belden wire or 0.999999% pure-silver single-strand wire that costs more than a Range Rover. It doesn't last.
