JMlab Utopia loudspeaker

I first met Jacques Mahul (the JM in JMlab/Focal) when my wife Kathleen and I traveled to Paris to cover HiFi (Hee-Fee) '96. The sound produced by the JMlab Grand Utopias—on a collection of many-chassis'd YBA electronics—got my enthusiastic vote for best of show (footnote 1). JMlab's large demo room was always packed to the rafters with avid listeners. (As a group, melomanes, as audiophiles are called in France, exactly mirror their stateside brethren in appearance and general demeanor. Yes, they're a raucous and demanding bunch!)

Audio Angler Reveals Secrets of Deep Bass

The performance of deep bass is one of the most perplexing questions we face. Timeless as the search for eternal youth or the meaning of life, the quest for truly satisfying deep bass has engaged generations of philosophers and inventors. Until recently, the subject was primarily one of conjecture, opinion, and hypothesis. Even so, almost no hard science had been devoted to this enduring issue.

DVD Working Group 4 to release DVD-Audio specification in May

The DVD Forum's Working Group 4 (WG-4) is expected to deliver the "0.9" version of its official DVD-Audio specification this month, with "1.0" to follow shortly. While information is scarce, it appears that WG-4 is talking about four different kinds of disc, each of which will be playable on one or two of three different kinds of players. And that doesn't include Sony's and Philips' "Super Audio CD" proposal (see Peter van Willenswaard's report on SACD a couple of weeks back on the website), or the Classic Records-led "DAD" format, which uses the provision of the DVD-Video specification for 24-bit/96kHz audio data. (DADs will play on DVD-Video players that have appropriate D/A sections---also see the past item on the web site.)

KEF RDM Two loudspeaker Sam's Space, October 1997

Stereophile is, in one sense, like a family—us younguns have to make do sometimes because the house is straining at the seams. When I first arrived in Santa Fe, for instance, I was told not to come to the office for a few days—the good news, John Atkinson informed me, was that I had a desk; the bad news was that nobody had a clue where to put it. The dilemma was solved in Solomon-like fashion by shoehorning my desk into the "listening room," which was already serving double-duty as audition space and speaker-measurement lab. If manufacturers visited, we'd sweep up all the acoustic damping from the floor and stash it in JA's office; and if JA needed to take measurements, I would be asked to work at home. It was a manifestly fair solution: inconvenient for everyone involved.
