To judge from the $6400 Mimesis 8, Goldmund walks its own way when it comes to power amplifier design. High-end solid-state amplifiers from US companies like Krell, Mark Levinson, Threshold, and the Jeff Rowland Design Group marry massive power supplies to large numbers of output devices (these often heavily biased to run in class-A), built on chassis of such nonmagnetic materials as aluminum. By contrast, the Mimesis 8 has a magnetic (steel) chassis, and uses a relatively modest power supply, that for each channel based on two main 4700µF reservoir capacitors. The 8 offers just two pairs per channel of complementary output MOSFETs (Hitachi K134/J49). These carry a modest bias current of around 80mA total.

Blame the Puritans! say I. The high end has always had an ostinato accompaniment of grumbles from those who appear to feel that it is immoral to want to listen to music with as high a quality as possible. In a recent letter, for example, Fanfare and Stereo Review contributor and author Howard Ferstler states that "the audio world has more products of bogus quality and shills promoting them than any other industry, bar none," and trots out the old saw that audiophiles "end up spending an excessive amount of money on equipment or tweaking techniques of surprisingly dubious quality."

666wil32.jpg"No pain; no gain." Thus goes the June 1991 offering from the Cliché-of-the-Month Club—(800) MOT-JUST—a saying that seems particularly appropriate for audiophiles with aspirations. High-performance loudspeakers fall into two categories. First are those exasperating thoroughbreds requiring endless Tender Loving Care and fussy attention to system detail to work at all. Take the Avalon Eclipse or the Infinity IRS Beta, for example: when everything is just fine, you put on record after record, trying to get through as much music as possible before the system goes off song again. On the other hand, speakers like the Vandersteens, Magnepans, B&W 801 Matrix, and KEF R107/2 appear to sound excellent even as you unpack them, before you've even put them in what you think might be the optimum positions in your listening room.

The question is: Are such unfussy designs really high-end? I mean, if they were truly high-performance speakers, shouldn't the owner have to suffer even just a little to reach musical nirvana? "A little pain; some sonic gain!" goes that other familiar saying.

You all know where you stand on this vitally important question. Me, I prefer to sit and construct the following graphical analogy. Draw a vertical axis and mark it "Absolute Performance." (The units are "gb," footnote 1) Now draw a horizontal axis and label it "Setup." (The units are "dU" for "deci-Ungers," footnote 2) Okay, sketch out an inverted V-shape. This curve, something like an engine's torque vs RPM curve, represents the manner in which a system's or component's performance changes according to how it is set up.

Our Delta L-1011 emerged from the cloud split-seconds before its wheels touched the waterlogged ground. "How much lower does the cloud cover have to be before they divert us to another city?" I asked Tom Norton. "About an inch," came the phlegmatic reply. (Ex-F4 pilot TJN categorizes any landing you can walk away from as "good.") But at least we had reached Atlanta, after a saga of air-traffic control problems, weather delays, and missed connections. (Does anyone remember taking a flight that wasn't full, wasn't late, and wasn't sweaty and stressful? Wasn't deregulation supposed to improve service by increasing the choices available to travelers?)

"I don't like Mondays!" sang Bob Geldof some years back, and I'm beginning to hate Mondays too. No, not for the obvious reason. You see, Monday is "hate-mail" day. Every day I get letters from Stereophile's readers. But for some reason known only to the mavens (or should that be Clavens?) of the US Postal Service, the ones pointing out my stupidity, dishonesty, and sheer incompetence as a human being arrive on Mondays.

For example: "Bits are bits, and it is therefore dishonest for Stereophile's writers to continue to insist that they can hear any differences between CD players or digital processors!" recently wrote an angry reader, canceling his subscription. (They always tell me they're going to cancel their subscription.) "Yeah, right!" thought I, having just sat through a comparative audition of, would you believe, digital data interconnects in Robert Harley's listening room. Some of the differences I heard were not trivial. They might even be audible in a blind listening test.

The name Joseph Grado is certainly not new to the transducer field, but the HP 1 is his first entry into the headphone market. The HP 1s are billed as "Professional Recording Monitor Headphones," and Grado is clearly targeting professional recording engineers and equipment designers in need of an accurate monitoring tool. Joe's designs, whether they be phono cartridges or tonearms, have never been ho-hum also-rans when compared to their competition. His products have invariably shown unique design ingenuity, often radically departing from accepted practice. His Signature Tonearm (the last such product he made, now discontinued), which I still use as a reference, is a case in point. The HP 1 headphones are no exception, being rather unusual in design, physical appearance, and construction.

I do quite a bit of headphone listening during the day, making use of their convenience to shut out the office hubbub while I get down to serious copy editing. The system I use is modest—a pair of no-longer-available Sennheiser HD420SLs driven by an Advent 300 receiver I bought for $75, with CD source provided by a Denon DCD-1500 II—but I get quite a bit of musical satisfaction from it.

John Atkinson examines the role of myth and magic in high-end audio.

This must be the month I drew the right straw to review "loudspeakers with three-letter initials." Elsewhere in this issue I describe my experiences with a pair of JBLs. Everyone knows that JBL stands for "James B. Lansing," founder of that company. You do, don't you? But PSB? If you've been paying attention here, you probably remember that JGH reviewed one of their loudspeakers back in May 1988. If you haven't, well, listen up. PSB is named after Paul Barton and his wife Sue, who formed Canada-based PSB in 1971. (Paul is still their chief designer.) The company was unknown in the US until just a few years ago, and still has a lower profile here than, well, certainly that other three-letter company. But not for lack of trying. They have at least 10 models—at last count.

What did you on your wedding night? I know what I did. All three times. But Casey McKee? He spent his wedding night at the end of October installing the new Lingo power supply on his Linn LP12. I know. I was there.
