Both in order to ascertain whether the samples of the Silver Seven-t that J. Gordon Holt auditioned were ostensibly the same as when Robert Harley had reviewed them, and to see if there were any measured reasons for this disparity between our writers' opinions, I carried out a set of measurements similar to those that Bob had done to support his original review.

The measurements were performed with Stereophile's Audio Precision System One, using high-power resistive loads built by Robert Harley. The distortion vs frequency graphs were made with the SS-…

Description: Solid-state monoblock power amplifier. Power output: 575W RMS into 8 ohms (27.6dBW), 900W RMS into 4 ohms (26.5dBW), 1000W into 2 ohms (24dBW), specified from 20–20kHz, both channels driven, with less than 0.5% THD (FTC). Frequency response: 3Hz–60kHz, –3dB. S/N ratio: >100dB, A-weighted into 8 ohms. IM distortion: 0.5%. TIM (transient intermodulation distortion): unmeasurable. Input sensitivity: 2.3V RMS. Power consumption: 1400W at full power.

When the 3-day AXPONA, aka Audio Expo North America, opens this Friday, April 12, in Chicago’s spacious Renaissance Schaumburg Hotel & Convention Center, the team of Editor-in-Chief Jim Austin, Technical Editor John Atkinson, Senior Contributing Editor Herb Reichert, and a lowly Contributing Editor with the initials JVS will be posting reports throughout the day and eve on many of the most exciting and noteworthy displays in the show’s 197 active exhibit rooms.

After 40 years of evolution, a new species of tweeter has appeared: the Linaeum TLS, which stands for True Line Source. This…

Everything stays resolutely where it belongs on the soundstage, including sounds located midway between each pair of…

Equipment used for this review included a Pioneer Elite CLD-99 laserdisc player, Sony DTC-2000ES DAT recorder, Lexicon DC-1 THX surround processor, and three Boulder 102AE power amps.

The video display included a Sony 1252 line-doubled video projector and 84"-wide 16:9 Stewart Ultramatte 150 screen. Software included a handful of recent CDs and blockbuster laserdiscs, a compilation of digitally copied music and soundtrack excerpts on DAT tape, and some stereo LPs of varying vintage.—J. Gordon Holt

Both Linaeum speakers have similar average B-weighted sensitivities at around 86dB/2.83V/m, While the Model 10's impedance (fig.1) doesn't drop below 6 ohms over most of the audio band, the Linaeum Center Speaker has an impedance of 4 ohms or below through the music and vocal "power region" in the lower midrange (fig.2), meaning that a receiver or amplifier rated into 4 ohm loads should be used.
