There are three requirements: You must invent a very good loudspeaker that sells for between $1000 and $2000/pair. You have to make enough of them, over a long enough time, to achieve a certain level of brand recognition and market penetration. And you must create a dealer network of reasonable size, with an emphasis on well-promoted specialty shops.
Here's something that's difficult to visualize but nonetheless true: If you attempt to isolate from their environment the working bits of a record player—the main bearing, platter, tonearm, and cartridge—by means of an elastic drive belt and a suspended subchassis of the usual sort, you'll create almost as many problems as you solve.
People love it when audio reviewers reach for that highest of all compliments: "I enjoyed the thing so much, I decided to keep it" (footnote 1). Manufacturers love it for obvious reasons. Readers love it because nuance is out of style at the moment, and the ambiguities implied by less decisive conclusions can be frustrating to adults who read with their mouths open. Publishers love it because strong, declarative statements have been scientifically proven, in double-blind reading tests, to attract subscribers.
I see a pattern taking shape: Roy Gandy's Rega Research offered their first CD player in 1996, which was 13 years after the medium was introduced to the public. Now, in 2006, some 50 years after Joe Grado designed and sold the first moving-coil phono cartridges, Rega has released one of those. The year 2016 may see the first Rega fluoroscope, or perhaps wire recorder. And it'll be a good one, I'm sure.
The good news: Domestic audio has survived its first half century and continues to live above ground. The bad news: At an age when most hobbies can enjoy the luxury of splintering into smaller factions that hate each other with impunity, ours isn't big enough. There are too few audiophiles on Earth to indulge that kind of specialization, let alone support the very different magazines that would ensue—so we'll never get to enjoy such promising titles as Liberal Tube Lover (not that I didn't try), The Elderly Skeptic, or, of particular interest, Cable Hating for People Who are Barely Audiophiles in the First Place.
