Thirty years later and I'm reviewing for Stereophile the Totem Skylight ($1000/pair), a two-way ported standmount similar to the Model 1, but closer in kinship and appearance to the…

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

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…
Description: Solid-state, class-AB monoblock power amplifier. Inputs: 1 single-ended (RCA), 1 balanced (XLR). Outputs: 1 single-ended (RCA), 1 balanced (XLR) pass-through loop for multiamping; 2 pairs five-way binding posts.

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,…
