In July 2008 I reviewed the intriguing Phono 2Ci moving-magnet/moving-coil phono preamplifier from Aqvox Audio Devices. Though it then cost only $1400, the Phono 2Ci's current-input circuitry represented a high-tech departure from the typical voltage-gain circuits used by almost everyone else. Although keeping its retail price so low resulted in some sonic compromises, it sounded remarkable, and tough to beat at the price.

Getting a review sample of this unique ultrasonic record-cleaning machine took me years; apparently, Audiodesksysteme Gläss, a small German manufacturer, couldn't keep up with demand. I've also heard from a few sources that reliability was not high in the company's early days, but that now all that's been sorted out, as has manufacturing capacity.

In the early 1970s, Stereophile's founder, J. Gordon Holt—a man I used to describe, with all due respect, as having been clothed by the haberdasher to the homeless—said that Audio Research's SP-3 tubed preamplifier was "the closest thing available, in fact, to the ideal straight wire with gain" ie, it would amplify the signal without editorializng in any way. Back then, the SP-3 cost $595. Today it would cost around $3500. But TAD's C600 dual-mono, solid-state, balanced preamplifier costs more than 10 times that: $42,000.

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.

What better way to celebrate the expiration of a noncompetition clause than to debut a product that has no competition? That's what Dan D'Agostino appears to have done with his Momentum monoblock amplifier ($55,000/pair)—his first new product since leaving Krell, the company he cofounded more than 30 years ago.

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.

A recent (unpublished) letter to the editor argued that the reference for audio perfection is the sound of real instruments in a real space. The writer claimed that, since the art and/or science of audio is advancing, and because it is a "scientific truth" that the closer you get to perfection, the less divergence there is components, that therefore there should be less difference in sound among the components listed in Class A of Stereophile's "Recommended Components" than among those in Class B, much less Class C. This should be true of loudspeakers, he said, but even more true of top-rated amplifiers, since "they inherently have less divergence."
