Immersion in various British pop groups followed, including the melodically graceful Chad & Jeremy, the polished Peter and Gordon, and sentimental pop purveyors Gerry and the Pacemakers. These acts provided not mere entertainment but an emotional refuge. Their tuneful, comforting repertoire was solace for a sensitive 6-year-old.

Hours were devoted to listening to a transistor radio, held close enough for the…

Their proven success with phono preamps has encouraged Simaudio to now go way…

The Cooper Hewitt Ojas system
The Cooper Hewitt system is built around a massive pair of horn-loaded speakers that nearly scrape the exhibit space's walls and ceiling. The screen-printed midbass horn is 7'9" tall, 6'4" wide, and 4'6" deep. It's driven by a TAD TL-1601A 15" dynamic woofer.

That midbass horn is a companion for the Ojas 1505 Multicell horn, a mid/treble horn based on the Altec 1505B Multicell. The Ojas 1505 Multicell is driven by a TAD 1401 compression driver. "It uses the geometry and size to provide horizontal dispersion control similar to the [Altec]…

I used DRA Labs' MLSSA system and a calibrated DPA 4006 microphone with an Earthworks microphone preamplifier to measure the Ruark Sabre-R's farfield frequency behavior and dispersion. I used an Earthworks QTC-40 mike for the nearfield responses and Dayton Audio's DATS V2 system to measure the impedance magnitude and electrical phase angle.

Ruark specifies the Sabre-R's sensitivity as 86dB/2.823V/1m, which was confirmed by my B-weighted estimate. The…
