Fifty years, man! By the time you read this, the dates will have passed during which promoters had hoped to stage a 50th anniversary Woodstock Festival—sadly, they failed in their effort—and Woodstock mania will have peaked and died—even pieces of the Woodstock stage are available to buy (I have two!). And yet the…

Like a child with a short-wave radio, what I seek from my audio system is a sense of something human—like a real person's voice from a faraway place, emerging miraculously from my speakers. Harbeth's P3ESR loudspeakers, driven by the Nelson Pass-designed class-A, zero-feedback…

Description: Solid-state stereo power amplifier with constant-transconductance output section. Power output: 20Wpc into 8 ohms (13dBW), 40Wpc into 4 ohms (13dBW).

I performed a full set of measurements on the Schiit Aegir, using my Audio Precision SYS-2722 system (see the January 2008 "As We See It"). Before doing any testing, I preconditioned the Aegir by running it at one-third power into 8 ohms for an hour. At the end of that time, the side-mounted heatsinks were hot, at 114.3°F (45.8°C) toward the rear, a little cooler nearer the front.

The Schiit's voltage gain into 8 ohms was slightly lower than the specified 22dB, at 19.5dB for both unbalanced and balanced inputs, the latter measured with the speaker output…

The first PSB Alpha was reviewed for Stereophile by Jack English in July 1992. A modest-looking two-way priced at just $199/pair, it combined a reflex-loaded 6.5" woofer using a plastic-doped paper cone with a 0.…

at some frequencies. Midrange coloration was low. The little PSBs did well with both male and female spoken voices, whether it was Richard Lehnert's introductions to the channel…

Description: Two-way, stand-mounted, reflex-loaded loudspeaker. Drive-units: 0.75" (19mm) aluminum-dome tweeter with ferrofluid and a neodymium magnet, 5.25" (133mm) polypropylene-cone woofer.
