Once upon a time, a little girl named Kirsten was playing in the woods when she spotted a gleam of light on the forest floor. Bending down for a closer look, she saw an astonishing sight: a lump of gold that seemed to grow from the very Earth. Her games forgotten, Kirsten scraped at the loamy soil for hours until, at last, the prize was hers: not a stone at all, but a beautiful horn made of solid gold. It was larger than any drinking horn Kirsten had ever seen, and was engraved from end to end with pictures of he-goats, snakes, a…

"It is my sincerest hope that our successors regard today's pronouncements of digital audio sound quality with the same combination of humor and incredulity with which we view Anna Case's assessment of Mr. Edison's machine."—Robert Harley, audio writer, 1990
When I wrote that conclusion to an editorial in the December 1990 issue of Stereophile, I expected that it would be years or even…
My self-imposed goals, which remain the same, are ambitious: I not only want to find a system or systems that a music lover can derive musical pleasure from, I also want to find a system that I can heartily recommend on the basis of "buy it once and buy it…
All of the listening for this issue's column was done using PSB's Imagine B two-way bookshelf speakers ($1000/pair), which I profiled in my February column. The Imagine B offers exceptional value for money; I continue to be very impressed with it overall, even as I remain somewhat frustrated with its lack of deep bass extension—you can't have everything, I guess. In that respect, the Imagine B is the "poor relation" to Harbeth's HL-3P-ES2. The comparison is by no means absurd—at half the price, the PSB has many of the…
Description: 2-way reflex-loaded, stand-mounted loudspeaker. Drive-units: 1" titanium-dome, ferrofluid-cooled tweeter; 5.25" polypropylene-cone woofer. Crossover frequency: 1.8kHz.

The Imagine B is very similar to PSB's Imagine T tower model, which Kalman Rubinson reviews elsewhere in this issue. The B uses just one of the T's reflex-loaded 5.25" woofers instead of two, but appears to have the same titanium-dome tweeter, so it should be very similar to the larger speaker in most respects. The B's voltage sensitivity was to specification, at 87dB(B)/2.83V/m, or 1dB below that of the Imagine T. The B's impedance with its port open (fig.1) dipped to 3.3 ohms in the lower midrange, with a combination of 5.1 ohms…

Both the power and the load selector switches employ a special mechanism which locks them securely into the chosen position. One pulls the actuator back to unlock the switch before moving it to the desired setting—just another…
