Fine Tunes #10 letters

A letter in response appeared in June 1999:

It's the amps what kills you

Editor: Please tell Jonathan Scull and Nagra ("Fine Tunes," April '99, p.63) that it is current that kills you, not voltage. Shame on them for not knowing their physics.—Tim O'Connor, Tim.Oconnor@ecolab.com

We also received the following two letters on the subject, neither of which was published at the time.

It's current and voltage that kills you

I read in "Letters" a criticism of Jonathan Scull for saying that high voltages can kill you. This guy said that it was the current that…

Fine Tunes #10 letters part 2

The audiophile electrician speaks out

Editor: As an electrician and audiophile, I thought I should correct some errors in Jonathan Scull's recent comments on grounding ("Fine Tunes," March '99, p.51). According to the National Electric Code, the neutral is the grounded conductor, whose job it is to carry the current back to ground. The "ground" is actually the equipment-grounding conductor and has no electronic purpose whatsoever. The sole purpose of the grounding conductor is life safety.

If a short were to occur in a piece of equipment, the chassis might become energized, and…

Legitimate Dealers Speak Out!

In his April 16, 2001 website essay "Where's Our Freedom of Audio Choice?" reader Jim Tavegia railed against the ubiquitous policy of manufacturers only allowing their products to be available through selected retailers. "If I'm willing to pay the UPS costs, it should be my prerogative to buy equipment anywhere I please," he wrote. This echoes a controversy that appeared in the print magazine 15 years ago. The affair started with some innocent-looking text written by Audio Cheapskate Sam Tellig in the December 1985 Stereophile (Vol.8 No.8):

Where to Buy

I generally recommend…

Legitimate Dealers Speak Out! Page 2

Papa Bach is gone now, along with almost every quality bookstore we had. A Los Angeles Times book reviewer recently pointed out that it's becoming harder than ever to get poetry or scholarly works published; with no retail outlet, such books have nowhere to go. Crown won't carry them, and the bookstores that would have are gone. Art suffers; literature loses some creative spark; new writers are never fledged—the stakes are too high. Remember, Crown orders 10,000 each of 20 titles, not 20 each of 10,000 titles. McBook has proved massively successful at driving out excellence with mediocrity…

Spendor S5e loudspeaker

I'm never more conservative than when the subject turns to home audio. And at the end of the day, I want little more than to preserve the hobby's finest institutions: Alnico magnets. Parchment cones. Mono. Sonata form. Ballads that actually tell stories. Give me tubes. Give me vinyl. Give me thin-walled hardwood cabinets, obsolete tweeters, and handmade polypropylene woofers. Give me the Spendor BC1.

It was a dark day when Spendor stopped making their first and finest loudspeaker—or so I used to think. I got over it when I heard the Spendor SP100 in the early 1990s, and when I admitted…

The Spendors arrived with nary a scratch, thanks to their well-designed cartons, and the newly designed MDF bases permitted easy installation and adjustment of their pointed feet (four per speaker). The feet, which are somewhat larger than one usually finds on a speaker of this size, can also be used to increase the S5e's effective height by a little more than an inch—a useful thing for tall listeners. Removable grilles of the usual sort are provided, although I preferred listening to the Spendors without them. Construction quality is evidently very good. The cabinets were cleanly made…

Spendor S5e loudspeaker Measurements

Sidebar 3: Measurements

With its small drive-units, the Spendor S5e exhibited the expected low sensitivity. I estimated a value of 82.5dB(B)/2.83V/m, which is significantly less than specified. Its impedance plot (fig.1) was unusual in that it had a much higher magnitude in the treble than in the midrange. While the latter ranged between 3.9 and 9 ohms, the impedance above 1kHz didn't drop below 10 ohms, and for much of the time remained above 20 ohms. As a result, if a tube amplifier with a typically high source impedance is used with the Spendor, the speaker's frequency balance will…
