John Atkinson's measurements of the Aavik U-380 integrated amplifier appeared to indicate that the amp had suffered damage, perhaps during shipping. Aavik U-380 measurements will be published as a follow-up review in a future issue.—Jim Austin
Dear XX,
No industry is ever immune to setbacks and disasters that loom large on our personal landscapes. Sometimes, they seem small in retrospect, but sometimes, the magnitude of the crisis is never diminished, and the only thing that matters is survival and managing the calamity with as much grace as we can muster. At RMAF, our hearts have been broken by some of those disasters, but our spirit has always triumphed. We have never shied away from difficult times. Over the years, we have endured many obstacles, including:
Alan Stiefel's unexpected death; The city electrical grid going…
I'm not in perfect agreement with my colleagues and friends who believe that RCA's Living Stereo LPs from the late 1950s and '60s are the best-sounding commercial classical recordings ever made. To me, the Decca SXL catalog outshines them sonically, in addition to showcasing the talents of an even greater roster of artists. But that's not to say I'm immune to their charms.
The RCA catalog contains some real gems.
Like some of you, my interest in RCA classical LPs was spurred by the writings of the late Harry Pearson, founder of the magazine The Absolute Sound. But by the time I…
Reviewing a new loudspeaker from Totem feels like destiny—as if a formative moment 30 years ago has come full circle. That's because the first genuine audiophile speaker I ever owned was Totem's now-iconic Model 1, a product whose arrival altered many audiophiles' expectations of how much great—and wide-range—sound a small speaker can deliver. It's still being made today, at least in spirit (footnote 1).
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…
I initially suspected that this midband clarity might be the result of a tipped-up tonal balance, but then I reconsidered: The speakers didn't sound etched or fatiguing. Rather, I think it was because I was accustomed to my LS50s' tonal character, which is darker overall. Through the Skylights, I was hearing more music than I was used to. And faster music, too: The Skylights served at the temple of tempo, keeping things running at a tight clip and on time.
The Skylights revealed the distinct characters of a wide range of recordings. While the music on Walters's album sounded brash,…

Sidebar 3: Measurements
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…
