Interviews

A mastering engineer's job is both to act as the final quality control before a recording goes out for manufacturing and, just as important, to apply to that recording the requisite technical finishing touches. Over the course of his career to date, mastering engineer Robert C. Ludwig has racked up more than 7500 album credits.

It had been years since Stereophile's last San Francisco Hi-Fi Show, when we'd hired him as a solo act, and yet the conversation was once again instant vaudeville, and I was again the straight man.

"The last time we saw each other, I think I just shook your hand and handed you a check."

"What, you didn't bring a check this time?"

"So this is your 16th solo record?"

"Is that all? Bach was doing a cantata a week. How many songs did Schubert write?"

"But he didn't do the words."

Arnie Nudell is one of a handful of designers who could justifiably be called founding members of the high-end audio industry. With Cary Christie, and John Ulrick, Arnie co-founded Infinity in his garage in 1968 and recently joined forces with Paul McGowan, the co-founder of PS Audio, to create Genesis Technologies, the Colorado-based company formed to build ultra–high-end loudspeaker systems.

I visited the Genesis factory in September 1994 and spent some time with Arnie and Paul discussing loudspeaker and amplifier design, and high-quality music reproduction. I asked Arnie how he became involved in high-end audio.

Is it because no one takes pot shots at you unless you're on top? Or are the most recent criticisms of Klaus Heymann and his diversified Naxos Digital Services empire on to something more?

To refresh: Heymann, a German entrepreneur who began selling cameras and stereos to American GIs in Vietnam, and later become the Hong Kong distributor of Bose and Studer audio gear, launched Naxos, a classical-music label specializing in budget-priced CDs, in 1987 (footnote 1). The label's name is also easy to pronounce in any language. Heymann began to build the Naxos catalog—now one of the largest classical labels—by recording young and often unknown artists and orchestras, most from Eastern and Central Europe. Soon, displays of Naxos CDs, all of their covers conforming to a uniform, instantly recognizable design, became to crop up in record stores large and small.

The most refreshing music I encountered at the huge 2015 Munich High End Show was an excerpt from David Chesky's children's ballet, The Zephyrtine, which Paul McGowan played in the PS Audio room. Hence it comes as no surprise that another of Chesky's recordings, his Rap Symphony, has just won the Independent Music Award (IMA) for Best Contemporary Classical Album.

It was with regret that I heard John Ulrick had passed away on May 20, 2015 due to complications from cancer. With Arnie Nudell and Cary Christie, John was one of the founders of loudspeaker manufacturer Infinity, a company that, with Audio Research, Magnepan, Mark Levinson, and Threshold, epitomized the nascent High End that emerged in the early 1970s. After leaving Infinity, John Ulrick started Spectron, to manufacture class-D amplifiers.

Just by chance, I met with the John Ulrick, in Los Angeles in late 1987, when he was doing some design consultancy on a switch-mode power amplifier to be used with the Sumo Samson subwoofer. As I had my Walkman Pro with me, I took the opportunity to tape some background from John about the birth of Infinity and about switching/pulse-width-modulated/class-D amplifiers—boy, can this man talk about switching amplifiers! The natural kickoff question was, How did Infinity get going?

Meridian's MCD CD player was perhaps the first audiophile-quality player to be introduced in the high-end market. I met with Bob Stuart of Meridian at the Winter Consumer Electronics Show in Las Vegas, in January, 1986 (footnote 1). My first question was about the name of the company he runs with industrial designer Alan Boothroyd:

J. Gordon Holt: Meridian in England is called Boothroyd Stuart, right?

Bob Stuart: Yes, the company is called Boothroyd Stuart, Limited, and the trademark is Meridian.
