Audacious Audio

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.

If you're reasonably handy, you can probably build your own digital-to-analog converter. It won't cost much, and if you're careful, and knowledgeable enough to understand and follow some rather technical instructions, or if you have patience enough to follow advice from a few different online discussion forums—and the judgment to distinguish the good advice from the bad—then the DAC you make may end up sounding very good.

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.

As editor, I love it when Stereophile reviews new equipment. "New" attracts readers. But there are good reasons to review stuff that's not totally new (though usually it is still shiny). The best reason is experience, first-hand: You hear a component at a show or in your own system. You're impressed and decide it deserves a closer look.

That's why I'm reviewing the CH Precision L1 line preamplifier ($34,500 in silver), which has been on the market for several years.

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.

A mono pair of CH Precision M10s ($210,000/pair as reviewed) declares its presence in capital letters. Each channel consists of two large units, each almost 2' high, linked by a total of four umbilical cords. While the "lighter" amplifier unit weighs almost 117lb, the toroidal transformer–based power supply unit tops out at nearly 172lb. That's a lot of metal.

High-performance audio has always been and will probably remain a cottage industry perpetuated by talented and visionary individuals whose products reflect their singular visions and whose companies often bear their names, though of course there are notable exceptions. One of them is Constellation Audio. No single star dominates the appropriately named Constellation Audio, which arrived on the scene at the 2010 Consumer Electronics Show with a seemingly impossible debut roster of products: stereo and monoblock amplifiers, preamplifiers, digital file player/DACs, and phono preamplifiers, each category of component represented by members of two distinct lines: no compromise and some compromise.
