The science of recording music is, to apply a metaphor from a very different context, akin to "breaking a butterfly on a wheel" (footnote 1). The art of recording is to make it appear as though that pinned insect could still take wing. I have been devoted to both the science and the art of recording music since 1965, when I was given a Grundig ¼" open-reel tape recorder as a birthday present. You could even say that my evolving interest in audio and my current position at the helm of Stereophile date back to my finding out how different a Shure SM57 dynamic cardioid microphone sounded from a Reslo Ribbon, even in mono, even at 3¾ips, when captured on that Grundig.

When I unpacked the review samples of Earthworks' Sigma 6.2 loudspeaker, I was reminded of a Pop Art exhibition I'd visited 30 years before, in London. Along with a stuffed drum kit and other of Claes Oldenburg's exaggerated-scale floppy sculptures, hanging from the Tate Gallery's ceiling was an enormous three-pronged, US-style AC plug made entirely of hardwood (footnote 1). Although the Sigma 6.2 is available in plain-Jane black MDF for $3500/pair, the optional solid-cherry cabinet, with its polished grain-streaked panels, has the same carved-from-solid, feel of the Oldenburg plug. I found myself wanting to stroke the speaker.

The June issue of Stereophile, which hits newsstands this week, spills some ink on the 30th-anniversary reissue of Pink Floyd's Dark Side of the Moon as a two-layer Super Audio CD (Capitol CDP 582136 2). Jon Iverson nominated the disc as June's "Recording of the Month," while I mentioned it in my "As We See It" column. This "fully loaded" SACD includes both multichannel and two-channel mixes encoded with the DSD system on a high-rez SACD layer and a two-channel "Red Book" transfer (16-bit word length, 44.1kHz sampling) on its CD layer.

The listing for the Rogue Audio M-120 monoblock power amplifier in the current issue's "Recommended Components" includes the comment, "Specified output power is 120W; JA measured just 100W into 8 ohms at clipping," which seems to suggest that Rogue Audio is overstating the amplifier's output power. This is not the case. The M-120 can be operated in both ultralinear pentode mode, in which it delivers the specified 120W, and in triode mode, in which it is specified at 60W. Our measurements were performed in triode mode; thus the 100W clipping power does, in fact, exceed the M-120's claimed output power of 60 watts in triode mode. Our apologies to Rogue Audio and to anyone confused by our lack of clarity.
