KEF LS50 Meta loudspeaker
There is no such animal as a "perfect loudspeaker." But within its limitations of limited maximum loudness—the LS50 Meta will work best in small or medium-sized rooms—and limited low-frequency extension (the reflex port is tuned to 51Hz), this immaculately finished minimonitor offers an almost complete absence of midrange coloration, a musically satisfying balance, and what I described in my review as a palpable "reach-out-and-touch" soundstage.

All this for just $1500/pair! Affordable almost perfection.—John Atkinson

The Riverside Church's Ambient Church presentation of Basinski's performance was scheduled for the evening of September 11, 2021—a Saturday. Saturday is my date night, which is sacred, so I was forced to decline.

Happily, though, my friend'…

One of my favorite recordings for these kinds of comparisons (as regular readers know) is "Buddy & Maria Elena Talking in Apartment (Undubbed Version)" from Buddy Holly's Down the Line Rarities (16/44.1 FLAC, Geffen/Qobuz). The component that…

I measured the Bryston B1353 with my Audio Precision SYS2722 system (see the January 2008 As We See It). The review sample was not fitted with the optional phono and digital input modules. Before I performed the testing, I preconditioned the amplifier by running it at one-eighth its specified power into 8 ohms for 30 minutes, as recommended by the CEA. After preconditioning, the heatsinks on the amplifier's sides were too hot to touch, at 148.5°F (64.8°C). The top panel was also hot, at 106.4°F (41.4°C). This amplifier needs plenty of ventilation.

Looking at the pictures, the products do look much more elegant, well made and ambitious than those from the usual hi-fi startup, but still, I'm thinking, I've heard a lot of clever and ambitious fluff like this before: a full-blown catalog of home theater–friendly speakers and,…

Description: Four-way loudspeaker in bass-reflex (or sealed) enclosure. Drive-units: 28mm beryllium-dome and two 28mm thin-ply carbon-diaphragm tweeters in a "DPC" waveguide; four 180mm thin-ply carbon-diaphragm woofers. Crossover frequencies: 500Hz, 1.1kHz, 4.4kHz. Frequency response: 80Hz–20kHz (±1.5dB), 22Hz–37kHz (–10dB). Typical in-room bass extension: 16Hz. Impedance: 4 ohms (3.2 ohms minimum). Sensitivity: 92dB/2.83V/m. Recommended amplifier power: 100–600W RMS. SPL capability (100Hz–20kHz): 117dB peak at <2% 2nd and 3rd harmonics.
Dimensions: 51.…
