The Skylights revealed the distinct characters of a wide range of recordings. While the music on Walters's album sounded brash,…

I initially suspected that this midband clarity might be the result of a tipped-up tonal balance, but then I reconsidered: The speakers didn't sound etched or fatiguing. Rather, I think it was because I was accustomed to my LS50s' tonal character, which is darker overall. Through the Skylights, I was hearing more music than I was used to. And faster music, too: The Skylights served at the temple of tempo, keeping things running at a tight clip and on time.

Sidebar 3: Measurements
I used DRA Labs' MLSSA system to measure the Totem Skylight's farfield behavior with a calibrated DPA 4006 microphone. For the speaker's nearfield responses, I used an Earthworks QTC-40 mike, which has a small, ¼"-diameter capsule that doesn't obstruct the sound from the woofer or port.
Totem specifies the Skylight's sensitivity as "88dB," presumably for 1W at 1m. My estimate was 85.4dB(B)/2.83V/m, which is about what I would anticipate from such a small loudspeaker and 1dB higher than that of the KEF LS50. However, while the Totem Skylight's nominal…
Soon after I took over preparing Stereophile's biannual Recommended Components listing from the magazine's founder, J. Gordon Holt, in 1986, I ran into a problem. With so many products listed, the magazine was running out of the necessary pages to include them all (footnote 1). To solve this problem, I looked at how long a typical product remained on the market before being updated or replaced. The answer was 3–4 years. I therefore implemented a policy that unless one of the magazine's editors or reviewers had continued experience with a product, it would be dropped from Recommended…
The bass guitar and kickdrum were reproduced with appropriate force and definition, though I felt I needed to remove the plugs from the Minos' upper ports to optimize the system's low-frequency reproduction. Mark Knopfler's vocalizing sounded clean and appropriately husky. But what really enthralled me about this atmospheric track was the depth of the soundstage. Some of the instruments had been mixed with various amounts of reverb. The piano that accompanies the acoustic guitar at the beginning before the verse, for example, was set way back in the soundstage, behind the voice and marimba…

I tested the Parasound Halo JC 1+ with my Audio Precision SYS2722 system (see the January 2008 "As We See It"). I preconditioned the amplifier by operating it at one-third the specified power into 8 ohms for an hour with the output-stage bias set to Normal. (With a class-AB output stage, one-third power results in the maximum dissipation in the output devices.) At the end of this time, the side-mounted heatsinks were hot, at 116.7°F (47.1°C). The top panel was a little cooler, at 98.9°F (36.7°C).
The Parasound's voltage gain into 8 ohms, set to Normal,…
I loved New Orleans music before I even knew what it was.
In the mid-1960s, I went to high school in Williamsburg, Brooklyn, which back then was a bleak, On the Waterfront landscape of dock workers and drifters hanging out in the pool halls along Bedford Avenue. We were warned to watch out on our way to track practice at nearby McCarren Park, because the pool halls were violent and confrontations often spilled out onto the street.
Around the corner from school was a small soda fountain, where I would hang out and play the Wurlitzer jukebox. It was my first audiophile-level…
