I obviously looked puzzled.
"To determine the ellipsoid of inertia, you put an axis anywhere through the center of gravity of the system, and calculate the moment of inertia around this axis. You find the two points on your chosen axis, either side of the center of gravity, where the moments are equal. You then choose…
The Audiomeca J1 is one of the more elegant turntable designs I have seen, being constructed from a black methacrylic sheet. In common with the Oracle, it dispenses with the traditional box construction for the plinth.
"Most turntable bases are like the sounding box of a…
Audiophiles discovered the benefits of headphone listening years ago. I still remember my first set of Koss Stereophones—nirvana for a college student in a tiny, shared dorm…
All of the headphones discussed here were comfortable to wear using eyeglasses—at least the eyeglasses I tried. But there are so many varieties of frames that I urge you to try before you buy with your glasses, if you plan to wear them with the headphones.
Similarly, all of these 'phones are of the open-back, circumaural variety: Circumaural means that they surround, rather than sit, on the external ear; open-back means that others sitting in the same general area as the headphone wearer will hear a rather scratchy, bassless rendition of whatever the listener…
Unless otherwise noted, the Stax headphones auditioned here were driven from the analog output of a Krell Reference 64 D/A processor. The transport was a Krell DT-10, connected to the processor by ST optical link with ST sync lock. The interconnects between the processor and headphone interface units were AudioQuest Lapis Hyperlitz, alternated with TARA Labs RSC where noted.
Comparison products included the Sennheiser Orpheus HE 90, the Koss ESP/950, and Sennheiser's own HD-580 driven by the HeadRoom Supreme dedicated headphone amplifier.—Thomas J. Norton

Bushman's Revenge is, in the purest sense, a power trio: Even Helte Hermansen on guitar, Rune Nergaard on bass, and Gard Nilssen on drums. They are joined on two tracks by Stole Storløkken's Hammond organ. They are from Norway. They crush. As much with the fury of their homeland's black metal as with the angst of 1960s American free jazz, they crush. They play instrumentals.…
Matthew B. Crawford's Shop Class as Soulcraft argues that an intimacy with manual trades may revitalize a connection to the material world that has been lost by those who spend their lives in offices or cubicles, staring at computer screens for eight to twelve hours a day, unable to quantify exactly what it is they do. I'm digging it. It aligns, in many ways, with a philosophy John…
