Sidebar 2: Review System
The players reviewed in this issue were broken-in for roughly a month before I sat down to listen. I fed them CDs, set 'em for infinite repeat, and hooked their fixed outputs to a 10k load (you can make this by soldering a 10k resistor between the signal and ground of an RCA plug, or alternately, you can just hook the player up to an input on your preamp, turned all the way down), which ensured that signal would flow through the audio circuitry, output coupling caps, wire, etc. If you leave the output jacks unterminated there's no signal flow, and all you…

The Sony joined the Denon DCD-2560 and the JVC XL-Z1050 as one of the three best test-bench performers reviewed in this issue. Its frequency response (fig.1) is practically a straight line, as is its de-emphasis curve (fig.2). The Sony's 0dB squarewave response (fig.3) is similar to the others, with a bit more discernible clipping of the ripple typical of its linear-phase filter. (This clipping is merely due to a conscious design choice concerning operation of the filter.) The crosstalk graph (fig.4) requires no comment.

A couple of weeks back, we posted a video profile of our Deputy Editor, Art Dudley, and received overwhelmingly positive feedback for Art—and deeply nostalgic comments about Listener Magazine, which he founded in late 1994, and which ceased publication after the September/October2002 issue.
Listener's writers included Herb Reichert, Michael Fremer, Alex Halberstadt, Rob Doorack, Adam Sohmer, and the late Harvey "Gizmo" Rosenberg, as well as guitarist Duck Baker, trombonist Roger Oyster, poet Robert Kelly, and a host of others. Features included equipment reviews, how-to articles, regular…

This is unquestionably the best recording Telarc has done to date. It is almost impossible to fault. If I were to pick nits, I would complain about a slight lack of air in the strings. The rest is, simply, superlatives!
The performances aren't quite that good, unfortunately.…
Bill Sommerwerck: The more intelligent you are, the less you know. I don't mean just the obvious use of "know," where one rigidly holds certain beliefs as absolute. I'm also suggesting that the properly disciplined mind replaces a lot of specific facts with a few generalities.
The inductive process (reasoning from general observations to specific principles) has obvious application to math and science and is just as applicable to such studies as economics or history. And once one understands enough basic rules, deductive reasoning allows one to predict the outcome of a particular set of…

It's not often I take up arms as a result of what I read in the hi-fi press, but there are moments. When I am told that all competently designed amplifiers used within their input/output limitations sound the same, I see red. And then there's this business about single speaker demonstrations (SSDs). . .

The reason I see red here is simple—I actually spend a lot of time listening to music using hi-fi equipment, and my ears tell me that SSDs work. BS seems content to use paper logic to prove that they don't, apparently without reference to any practical…
In critic speak, "fascinating" is a word that can go either way. On one hand there's the fascinating which translates to a polite way of saying that as ideas go it had potential, but in execution it's really only for diehard fans of the artist. Or maybe, it's not really for anybody.
A perfect example of the opposite positive use of fascinating is Shorter By Two, an idea that probably shouldn't have worked but in practice succeeded in ways that most people could never have imagined. Originally released in 1984, these adaptations of Wayne Shorter's original compositions played by two pianos…

One of Crystal Clear's earlier releases (1978), this has very distant, directionally vague sound, but the sound (stupendous by standards of only a few years ago) cannot stand in the way of two of the most exciting performances of these potboilers that have ever been committed to…
The KSL ($1800, $2100 with phono section) is a one-box line controller/preamplifier, just 2.25" high, with a nominal voltage gain of 10dB, or 3x. Despite its moderate price, the KSL is distinguished by having balanced outputs (via industry-standard XLR connectors), as well as two balanced inputs. Conventional single-ended, unbalanced outputs are also available via a pair of gold-plated phono sockets. Two unbalanced inputs are provided, plus a third via the tape monitor switch. The tape output is unbalanced, derived from the selector switch setting, while the main outputs may be used…
