Audacious Audio

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.

In the very first copy of Stereophile I encountered, back when issues were digest size, one review infuriated me. The writer went on at inordinate length about the fine wines he'd consumed during the review period. On and on he went, gushing about the costly drinks, until I exclaimed (in a sentence laced with expletives), "What in the world does any of this have to do with audio?!"

When I was a young man, blind dates were always laced with anxiety. (Proms were even worse. Once, when I arrived in a rented tux and my father's prized dress gloves, my date's father ordered me to take out the trash.)

The Kingdom of Audiophiledom rests on a paradox. Inanimate audio systems and rooms aim to deliver music that animates our senses and touches our souls. The inherently lifeless exists to bring music to life.

This holistic reality—that systems and rooms function as living organisms where every part is interconnected and interrelated—came home to me when, during one of the first AXPONAs in Chicago, I entered a long, cavernous basement room with several spongy "conference room" walls. "There is no way that any setup can deliver good sound in this room," self said to self. Yet, the system sounded unbelievably good.

Are well-heeled audiophiles ready for a knob-free future? Gryphon Audio Designs thinks so. In contrast to Gryphon's volume knob–dominated Pandora preamplifier, the Danish company's new Commander offers nothing on its bold front panel to grab or turn.

Instead, there's a large, extra-thick, triangular glass protuberance that extends dramatically below the chassis's vertical dimension. That's where you'll find an "on/off" button, the main unit's only physical switch.

Like the proverbial pot of gold, darTZeel's golden equipment beckons. That, at least, is how it felt in January 2010, when John Atkinson and I ended our coverage of T.H.E. Show Las Vegas in the room shared by darTZeel, Evolution Acoustics, and Playback Designs. Listening to darTZeel's discontinued NHB-458 monoblocks (footnote 1) and NHB-18NS reference preamplifier (now updated), I was transfixed by the fullness of the system's midrange and overall beauty of the sound. "It was as though the system was opening its heart and welcoming us in," I wrote. "That's how warm and nurturing the sound was."

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.
