Budget Component Reviews

If speakers were cars, the Infinity IRS Beta and B&W 801 Matrix would represent the luxury end of the mass market, with perhaps the Celestion SL700, Quad ESL-63, and MartinLogan Sequel II analogous to rather hairy, temperamental sports cars—the Porsche 911, for example. But most people don't buy Porsches, or even Lincoln Town Cars; they buy Hyundai Excels and Ford Escorts. In the same way, when the car is garaged for the night, they don't sit down in front of IRS Betas; in all likelihood they listen to their records with a compact two-way design. If competently designed, a small two-way can give a great deal of musical satisfaction, and, to take a current hobbyhorse of mine out for a trot, if a designer can't produce an at least competent two-way loudspeaker, he or she has no business trying to design larger, more ambitious models—there's nowhere to hide your lack of talent if all you have to play with is a tweeter, a woofer, a rectangular enclosure, and a handful of crossover components.

One of the first affordable loudspeakers I reviewed for Stereophile was the original Paradigm Reference Studio/20 bookshelf model, in the February 1998 issue (Vol.21 No.2). At the time, I felt that the $650/pair speaker was a breakthrough—although not completely devoid of colorations, its ratio of price to performance set a benchmark a decade ago. I kept the Studio/20s around for several years to compare with other bookshelf speakers I reviewed, and they remained listed in Stereophile's "Recommended Components" for several years after that. The Studio/20 is now in its fourth (v.4) iteration, so I thought I'd grab a pair to hear how they compared with current affordable bookshelf designs.

Asked how to make a guitar, the celebrated luthier Wayne Henderson offered a straight-up answer: "Just get a pile of really nice wood and a whittling knife. Then you just carve away everything that isn't a guitar." (footnote 1)

The making of a preamplifier seems more or less the opposite. You start with a simple volume control and a couple of jacks, then add whatever you think constitutes a preamplifier. Choices might include electronic source switching, line-level gain, phono-level gain and equalization, tone controls, tone-defeat switches, a balance control, a headphone jack, an iPod input, and maybe even a digital-to-analog converter with a USB receiver. The sky is pretty much the limit.

Whether one was surprised, in 2010, by the success of Peachtree Audio's iDecco may have more to do with age than anything else. My peers and I wondered, at first, who would want their high-end integrated amps to come bundled not only with digital-to-analog converters but with iPod docks, of all things; at the same time, younger hobbyists wondered who in the world still wanted their integrated amps to contain phono preamplifiers. (Respect for the elderly, myself especially, prevents me from adding "and mono switches.") Color me chastened.

It's common knowledge that manufacturers tune the sound of each DAC model. There are the facts of product design and marketing: inputs, outputs, case materials, price points. After that, what's left are the trade-offs of different circuit designs and filter options, which are chosen with care—each has a subtle yet telling effect on a DAC's sound. Most designers try to go from bits to analog with minimal deviation from perfect. But when you look at the measurements and listen closely, you realize that perfect is elusive. One has to make choices.

As with so many other things, from cell phones to soy milk, the idea of a portable MP3 player was something I at first disdained, only to later embrace with the fervor of any reformed sinner. But not so the idea of a high-fidelity iPod dock: Given that I now carry around several hundred high-resolution AIFF files on my own Apple iPod Touch, the usefulness of a compatible transport seemed obvious from the start. Look at it this way: In 1970, whenever I bought a music recording, I could enjoy it on any player, in any room in the house. In 2010, why shouldn't I enjoy at least that degree of convenience and flexibility—without resorting to a pair of tinny, uncomfortable earbuds?

In some ways, building an inexpensive yet musical two-way loudspeaker is a greater design challenge than creating a cost-no-object reference product. Although the latter is a much more complex endeavor, the venerable two-way box seems to bring out the creativity and resources of the designer. Rather than throw money at the product in the form of more expensive drivers, enclosures, or components, the designer of a low-cost two-way is forced to go back to the basics, rethink closely-held tenets, and rely on ingenuity and sheer talent to squeeze the most music from a given cost. Consequently, the inexpensive two-way is the perfect vehicle for designers to develop their skills. If one has mastered this art form, one is much more likely to achieve success when more ambitious designs are attempted.
