I performed a full set of measurements using my sample of the top-of-the-line Audio Precision SYS2722 system (see www.ap.com and the January 2008 "As We See It"). The Corona C15 has a switching output stage, which produces ultrasonic noise that would overload the Audio Precision's input circuitry. To eliminate this noise, I carried out most of the tests using, ahead of the analyzer, Audio Precision's AUX-0025 passive low-pass filter).
Before performing any measurements, I ran both MBL Corona C15s for an hour at one-third the specified maximum power of…
What a good rogering can do
In response to my review of Music Hall's USB-1 turntable, that company's founder and president for life, Roy Hall, noted my detailed explanation of the product, diverse taste in music, and keen attention to minutiae. He then offered six words of final observation that will, if there is any justice in this world, go down in Stereophile lore: "The kid has gotta get laid."

Hall was right, of course. And, perhaps as he anticipated, now that I'm regularly getting laid (thanks, Ms. Little), I've developed a different relationship with hi-fi. I don't care about it…
The a15.3 measures the same as the c-dac15.3, weighs about three pounds more, and comes with the same robust AC cord and attractive remote control. (Both models can be controlled with a single one of these remotes.) Inputs can be selected either from the remote control or by pressing one of the buttons, clearly labeled "one" through "five" and "phono," on the front panel. Both amp and CD player have handsome faceplates of brushed aluminum, available in any color you want, as long as it's black.
The Music Halls replaced my Arcam's A19 integrated amplifier ($999). Speakers were…
For Jason Victor Serinus, one of the highlights of the 2013 T.H.E. Show in Newport Beach, California, was the public debut of the Sopranino—a horn-loaded, self-polarized, electrostatic supertweeter from EnigmAcoustics. In his report, Jason wrote about the sound of a pair of Sopraninos used atop Magico V3 speakers: "only folks with severe hearing loss would have missed how the sound opened up when the Sopranino was switched in." Well, as you can read later, I don't have hearing loss, and I did also hear an improvement with the Sopranino. So when I visited the Californian company's dem room…

I used DRA Labs' MLSSA system and a calibrated DPA 4006 microphone to measure the EnigmAcoustics (Enigma from now on) Sopranino's frequency response in the farfield, and an Earthworks QTC-40 for the spatially averaged room responses. It was difficult to estimate the Sopranino's voltage sensitivity, as I usually calculate this with a 20kHz bandwidth and, as you will see, the Enigma supertweeter's output is mainly higher than that frequency. But the sensitivity below 20kHz appears to be 87dB/2.83V/m, with the switch reducing this by the specified 3dB.

Before there were jam bands, before the term even existed in fact, there was a fabulous, funky assemblage called Little Feat. Led by keyboardist Bill Payne, drummer Richie Hayward and the band’s resident genius guitarist/singer/songwriter, the late Lowell George, the band was completed by guitarist Paul Barrere, percussionist Sam Clayton, and bassist Kenny Gradney, all of whom joined after the Dixie Chicken record. Their live shows and studio records are, along with The Allman’s and The Dead, the rock upon which today’s overripe jam movement was built. One look at the video or a listen to…
Paul Bley's Play Blue: Oslo Concert (on the ECM label) is a bracing solo piano album. Think Keith Jarrett, with less Rachmaninoff and more Monk, but the distinctions sway on the margins. Bley too is a romantic improviser, immersed in jazz idiom but classically trained (and he lets it show, though less showily than Jarrett).
Another difference: Bley recorded this in 2008, when he was 75, and he sounds just as energetic as when he was 20, back in 1953, on his debut LP, Introducing Paul Bley, with Charles Mingus and Max Roach as sidemen. (He also recorded in the '50s with Charlie Parker,…
