The phenomenon of the "singing flame" has been known since the 19th century. Place electrodes either side of a flame and, if you apply a high enough audio-modulated voltage to those electrodes, the ionized particles in the flame will cause it to emit sound. (Search YouTube for "singing flame" and you'll find many examples.) This principle was developed into a practical loudspeaker in 1946 by a French inventor, Siegfried Klein, who confined an RF-modulated arc to a small quartz tube, coupled it to a horn, and called the resulting speaker the Ionophone. An intense radio-frequency electrical field ionizes the air between inner and outer electrodes to produce a distinctive, violet-tinged yellow flame in the quartz combustion chamber. When the RF field is modulated by the audio signal, this causes the almost massless ionized flame to expand and contract in what should be a perfectly pistonic manner.

Volti Audio's Vittora, a borrowed pair of which now sit at the far end of my listening room, is a great loudspeaker and, at $17,500/pair, a seriously great value. After a few weeks with the Vittora, I find myself convinced by the naturalness, momentum, and force that it found in every record I played: This is surely one of the finest horn-loaded speakers made in the US.

A new integrated amplifier called the Lars Type 1, which made its debut at the 2009 Consumer Electronics Show, has given my notion of a dichotomy between mainstream audio and alternative audio a severe beating. In that sense, the Lars Type 1 has been a life-changing product, although the change took longer than expected for me to digest.

If you've followed their story here and elsewhere, you probably know that Tokyo's Shindo Laboratory (footnote 1) has a reputation for defying the two most monolithic of all high-end audio commandments.

Rarely has the debut of a new loudspeaker company and its inaugural model created as big a buzz as did Lumen White and their Whitelight speaker at the 2001 Consumer Electronics Show. Driven by Vaic tube amplifiers in one of the larger corner rooms at the Alexis Park Hotel, the big Whitelights had a look and a sound that attracted continuous crowds. Of the questions among audio cognoscenti that I overheard at the end of each day, two of the most common were "Hey, did you hear those Lumen Whites?" and "What? Can you speak louder?"

When Philip O'Hanlon of On a Higher Note, Luxman's US distributor, delivered the B-1000F monoblocks, it took three of us to wrestle their shipping crates into my house and then into the listening room. Once they were unpacked, it still took two of us to maneuver each of them into position—at 141 lbs and 16.9" wide by 11.6" high by 23.3" deep, the B-1000F is far from easy to shift. Fortunately, O'Hanlon had also brought along a pair of Stillpoint stands specifically made for the Luxmans; the B-1000Fs certainly wouldn't have fit into my equipment racks. (The Stillpoints are lovely things. I recommend 'em if you go for the B-1000Fs.)

When O'Hanlon told me the price of the stands—$2500/pair—I asked what the amps cost.

"Fifty-five," he said.

"You mean the stands are 45% of the price of the amps?"

At the 2012 Consumer Electronics Show, I spoke with Lyra's Jonathan Carr about the Atlas. He told me that, rather than having started as a blank sheet of paper, the Atlas is an outgrowth of the Kleos ($2995), which I reviewed in January 2011, when I thought it Carr's best balanced design yet, even if it didn't have quite the resolution of the Titan i. Like the lower-priced Delos ($1650, reviewed in August 2010), the Kleos included Carr's New Angle technology, which mechanically aligns the coils to be perfectly positioned relative to the front and rear magnets when the stylus is in the groove.

Is the high-performance audio industry stagnating? Are designers simply repackaging the past? Cynics claim so, but to me it seems that making that case gets harder by the day, as a parade of veterans continue to produce their best work.

"So what kind of music do you listen to?" I heard myself asking Leif Mårten Olofsson, designer of the Coltrane, Coltrane Alto, Duke, Miles II, Mingus III, and Monk loudspeakers, before I could take it back. The small company, headquartered in Göteborg, Sweden, where Volvos are made, has been building and marketing loudspeakers for the past six years, though Olofsson confesses he's been building them for 30 years, ever since he was 12.

Show a time traveler from the 1920s an iPad and most likely he'd neither know what he was looking at nor what it might do. Show him a loudspeaker, even one as advanced as Magico's new Q5 ($59,950/pair), and he'd probably know exactly what it was and what it did, even if what it's made of might seem to have come from another planet.

We wrote a long, rather unkind report on the HQD, pointing out that, if that was typical of the way it was supposed to sound (And why not, after Mr. Levinson had installed and tweaked it?), then it had to be the most expensive bomb ever to be made available for civilian use. Mr. Levinson responded with a phone call during which he:

1) Told us we had not heard it at its best, but refused to address himself to our specific criticisms;

2) Claimed that many practicing professional musicians felt the HQD to be "extremely realistic";

3) Informed us that, since he sold very few HQD systems and would soon be discontinuing them anyway because Quad had ceased making those speakers, the "sensible" thing to do would be to kill the report; and

4) Mentioned, just in passing of course, that he was currently writing a feature article for Time on the subject of "underground" audio magazines.

Before launching into Stereophile's first-ever report on a Mark Levinson product, an important point needs to be clarified. Although Mark Levinson products were originally made by Mark Levinson, they are no longer. Au contraire, Mark Levinson products are now being made by Madrigal, Ltd., which bought Mark Levinson Audio Systems' assets and trademark two years ago. Mark Levinson's products, as distinguished from Mark Levinson products, are now being manufactured by a company called Cello. But the subject of this report, the Mark Levinson ML-7A preamplifier, is a product of Madrigal, Ltd., not of Cello. Now that I've made that all perfectly clear, we may proceed.

Over the past two and a half years, I've auditioned and reviewed a number of digital audio products. It has been a fascinating experience both to watch digital playback technology evolve and to listen to the results of various design philosophies. The road to more musical digital audio has been a slow and steady climb, with occasional jumps forward made possible by new techniques and technologies. Making this odyssey even more interesting (and confounding), digital processors seem to offer varying interpretations of the music rather than striving toward a common ideal of presenting what's on the disc without editorial interjection.

The arrival of the Mark Levinson No.30 digital processor more than 2½ years ago marked a turning point in digital-audio reproduction. Although the No.30's $13,950 price tag put it out of reach of all but a few audiophiles, its stunning performance suggested that much more musical information was encoded on our CDs, waiting to be recovered by better digital processors. Further, it was inevitable that this level of performance would become less expensive over time. I was more excited by the No.30 than I've been over any other audio product. In fact, its musical performance was so spectacular that it alone occupied the Class A category in Stereophile's "Recommended Components."

Mark Levinson founded Mark Levinson Audio Systems in 1972, but sold it, and the right to market audio gear under his own name, to Madrigal Audio Laboratories, then owned by the late Sandy Berlin, in 1984. Harman International bought Madrigal in 1995. As well as Mark Levinson, Harman's Luxury Audio Group now also includes digital processing pioneer Lexicon, speaker manufacturer Revel, and JBL Synthesis. The Mark Levinson brand is now headquartered in Elkhart, Indiana, at the Crown Audio facility, another Harman-owned brand. The No.53 ($25,000 each; $50,000/pair) is Mark Levinson's first new Reference series monoblock since the No.33, way back in 1993, when Madrigal owned the company. Like other Mark Levinson products, it is manufactured at an independent facility in Massachusetts.
