Audacious Audio

The whole idea that different CD transports have different sonic characteristics when driving the same digital-to-analog converter is a vexing problem. It is easy to prove that even the cheapest CD players recover the data stored on most CDs with bit-for-bit accuracy, thus disproving the widespread and erroneous belief that errors in the digital code are commonplace and affect presentation aspects such as imaging, soundstage depth, textural liquidity, etc (footnote 1). If the datastream driving the digital converter is comprised of the same sequence of ones and zeros, regardless of the transport, what other factors could account for the sonic differences between CD drives reported by many listeners?

The Type A has served as Snell Acoustics' flagship loudspeaker since 1974. The Type A Reference System reviewed here is the sixth update of the late Peter">http://www.stereophile.com/floorloudspeakers/378snell/index4.html">Peter Snell's original three-way floorstanding design, and is the most radical departure from Snell's">http://www.stereophile.com/floorloudspeakers/378snell">Snell's original. Gone is the pair of "upright bricks of polished wood and stretched cloth" (footnote 1) that delighted decorators because they functioned best against a wall. Today's Type A Reference $18,999 price tag (footnote 2) purchases two tall midrange-tweeter towers, two huge subwoofers, two short but heavy enclosures housing the outboard passive crossover networks, and a small electronic crossover.

Much has happened in the analog world since I reviewedhttp://www.stereophile.com/analogsourcereviews/796">reviewed; SME's flagship Model 30/2 turntable for the March 2003 Stereophile (footnote 1). Back then, spending $25,000 on a turntable (without tonearm) was an odd extravagance intended only for those seriously committed to the format, and who already owned large LP collections. Although new LPs were being pressed in growing numbers, the resurgence of vinyl was still spotty, and the long-term prognosis for the old medium remained in question.

It's been a while since I auditioned a Meridian CD player in my system. I had enthusiastically reviewed the English company's groundbreaking Pro-MCD">http://www.stereophile.com/cdplayers/285meridian">Pro-MCD player in early 1986, and over the years had kept up with the progress they were making in digital playback, either through my own reviews or by performing the measurements to accompany reviews by other Stereophile writers. The 508-24 player, reviewed">http://www.stereophile.com/cdplayers/590">reviewed by Wes Phillips in May 1998, was one of the finest digital products of the 1990s, I thought. But when Meridian began promoting surround sound and DVD-Audio at the turn of the century, their goals became somewhat incompatible with my own. Yes, I can appreciate what surround playback can do, but my own musical life is still solidly rooted in Two-Channel Land.

You've seen the ads from YG Acoustics: "The best loudspeaker on Earth. Period." It sounds arrogant. But come on—high-end audio has never been a field of shrinking violets. When Ivor">http://www.stereophile.com/interviews/1101ivor">Ivor Tiefenbrun of Linn announced that the turntable, not the cartridge or loudspeakers, dictated the sound quality of an audio system, that was a man convinced that he was right and taking on the world. And was Krell's Dan">http://www.stereophile.com/interviews/1203dagostino">Dan D'Agostino any less arrogant when, in 1980, he introduced the KSA-100 power amplifier? In a world where small size and high wattage were the norms, didn't it take a pair of big brass 'uns to bring out a honkin' huge slab of metal that put out only 100Wpc?

I can't think of a product that was as eagerly anticipated as was Ayre's KX-R preamplifier ($18,500). Following in the footsteps of Ayre's MX-R">http://www.stereophile.com/solidpoweramps/407ayre">MX-R monoblock amplifier, a Stereophile 2007">http://www.stereophile.com/features/1207poty/index9.html">2007 Product of the Year, and milled, like the MX-R, from a 75-lb billet of aluminum, the KX-R also shares with its monoblock stablemate the Ayre ethos of zero feedback and fully balanced operation. But what really caused the buzz was the declaration by Ayre founder and chief designer Charles">http://www.stereophile.com/interviews/610">Charles Hansen that the KX-R, with its use of a technology he calls Variable Gain Transconductance (VGT) to control the volume, would set new standards for signal/noise ratio.

Based in the Czech Republic, KR Enterprise is headed by an occasionally gruff Dr. Riccardo Kron and his American-born wife, Eunice, who operate the company out of a partially abandoned factory that was once part of the state-owned Tesla High Vacuum Technology facility in Prague. The Swiss-funded company is unique in that it manufactures both amplifiers and the tubes that power them. KR's tubes have found favor with other amplifier makers as well—especially the 300BXS, electrically identical to a standard">http://www.stereophile.com/features/229">standard 300B but rated at 25W in class-A.
