Audacious Audio

Of all the components to be seen and heard at an audio show or in a dealer's showroom, the most memorable and attention-grabbing are inevitably the super-speakers—bogglingly expensive, filled with cutting-edge engineering and exotic materials, of mammoth size and weight, with full-range reproduction that shakes building foundations and extends far enough up top to disrupt the navigation of bats. Survey the field, and the biggest Wilson, Aln, JMlab-Focal, Burmester, EgglestonWorks, and Nearfield Acoustics models, to name a few, fit that description.

Four years after its launch, the CD medium would appear to have come of age, at least in production terms. Annual player manufacture is now big business, and there is hardly a major audio brand without a CD machine to its name—even such analog stalwarts as Audio-Technica and Shure have succumbed.

There's no place for fashion in epidemiology, aeronautical engineering, or the mining and storage of uranium. Fortunately, domestic audio is less serious, its goals more scattered and ambiguous, than those and a thousand other pursuits.

And so, throughout the 20th century, any number of trends in domestic audio popped up their heads, some remembered as fads, others as legitimate approaches to playback. Among the latter are amplifiers whose output sections operate in single-ended mode, in which the entire signal waveform is amplified by a single device.

It takes audacity for a company that already builds one of the finest DACs on the planet, which is already expensive, to set out to build one that's so much better that it warrants an extra digit in the model number and a much higher price tag. But then CH Precision has never lacked audacity.

There's a school of thought that maintains that among all hi-fi components, the D/A converter is easiest to perfect or come close to perfecting. Just make sure that every sample is converted accurately, that there's little rolloff in the audioband, that aliased images are suppressed almost completely, and that background noise is extremely low, and you have a top-quality D/A processor. Use of a high-quality DAC chip is assumed.

Stereophile strives to distribute the wealth equally. Did that get your attention? What the statement refers to, in terminology devoid of dollar signs, is that Stereophile attempts to review products from different companies rather than repeatedly focus on products from a single company.

CH Precision's massive, versatile, technologically sophisticated, 165 lb M1.1 power amplifier ($54,000 configured for stereo) can easily crush your foot if you're not careful when installing it. But the more important consideration is this: Can this cool gray techno-square sing and dance without stepping on its own feet?
