Fig.1 shows the MG2.6's electrical impedance magnitude (solid line) and phase (dashed line). With a value averaging 5 ohms in the bass and 3.5 ohms in the treble, with a rise in between due to the crossover, the speaker is a reasonably demanding load in terms of current draw, though the phase curve indicates it to be resistive—ie, not significantly departing from a 0° phase angle—over much of the audio band. The MG2.6s shouldn't give good tube amps any problems as long as they're driven from the 4 ohm output taps. The very slight wrinkles at 50 and 60Hz presumably…
Publisher's note: The following article, from the early days of Compact Disc, is presented with no claim for absoluteness. (In fact, just as we go to press in the spring of 1986, we received a manuscript from Philip Greenspun, Product Review Editor of Computer Music Journal (Cambridge, MA), who had precisely the opposite result when comparing CD to analog versions of the same recording, though it was unclear that his test procedures were as thorough as in the tests by these authors, footnote 1.) The tests described are neither single- nor double-blind, and the author's decision to forego…
The Music
We chose four selections that would allow us to examine different aspects of sound reproduction, and obtained identical material in three forms: Nakamichi cassettes recorded on TDK metal tape using Dolby-C and made from a composite master tape (footnote 4); original Sheffield direct-to-disc vinyl records; and compact discs produced from the same composite master tape used for the Nakamichi cassettes (footnote 5). We cleaned the records with a VPI-16 record cleaning machine, and immediately treated them with LAST record preservative. We also used Stylast on the cartridge during…

Amanda McBroom, "Gossamer": This selection's direct-to-disc recording session used a digital recorder as a safety backup. This was the only selection in our comparisons that was truly digital from recording to playback media. We included it in an attempt to quantitatively compare differences between CDs made from original analog or digital master tapes with their D-to-D counterparts. The CD version of "Gossamer" definitely contained more high-frequency information and overall clarity than the record. The piano accompaniment, in particular, sounded more "alive." The CD also conveyed more…
Given its engrossing, frequently radiant score, unflinching look at its timely subject matter, and superb cast of singing actors, Pentatone's live hi-rez recording of the premiere of Mason Bates and Mark Campbell's opera, The (R)evolution of Steve Jobs, fully deserves the Grammy recently bestowed upon it by the Recording Academy.
I auditioned the recording after first enthusiastically reviewing the 2017 Santa Fe Opera world premiere, then cheered the differently cast 2019 Seattle Opera production (whose second cast is completing its run as this review appears on-line). I have no question…
Our 180-page April issue is hitting newsstands, mailboxes, and tablets this week and, as always with Stereophile's April issues, it includes the revised and updated edition of our "Recommended Components" feature—capsule reviews of the best-sounding gear available. (The listing this year is longer than ever, so many of the categories will actually be included when the listing is posted to the site this week.)
And featured on the April issue's cover is Klipsch's RP-600M speaker, which features a horn-loaded tweeter. Read Herb Reichert's report to see how he felt about this little gem. Art…

In 1967, the year the Byrds would fire him, David Crosby sits in a room—a small space, from the sound of it—with a cheap microphone and a recorder of dubious merit. He's improvising some jazzy, open-tuned acoustic guitar strumming, adding nonlexical vocables on top. He then files away the resulting tape—clearly ahead of its…
The dichotomy between what is measured and what is heard has resurfaced in recent months. Jon Iverson discussed it in his "As We See It" in our December 2018 issue, and I followed up on the subject in my January 2019 "As We See It." These further thoughts were triggered by an e-mail exchange I had last December with Stereophile's longtime copyeditor, Richard Lehnert.
In a note attached to his edit of Kal Rubinson's review of the Revel F228Be loudspeaker in our February issue (p.87), Richard had written: "Unless you're sitting in, say, one of the first five rows at a classical concert,…
Components listed here have been formally reviewed in Stereophile and have been found to be among the best available in each of four or five quality classes. Whether a component is listed in Class A or Class E, we highly recommend its purchase.
Each listing-in alphabetical order within classes-is followed by a brief description of the product's sonic characteristics and a code indicating the Stereophile Volume and Issue in which that product's report appeared. Thus the May 2018 issue is indicated as "Vol.41 No.5."
Some products listed have not yet been reported on; these are…
