Custom preamps first, a company second.

Grace Design grew out of one engineer’s custom work. An archived version of the company’s website from 2004 says that Michael Grace, an audio engineer and designer, began building single, made-to-order audio products for “a small, devout following of recording engineers and artists” in 1990. As demand grew for his microphone preamplifier, the same page says, Grace Design was founded in 1994 and began production of the original model 801 preamp. Sound On Sound also dated the business to 1994 in a 2011 review.

Today the company describes itself as “a family owned and operated company” founded “by brothers Michael and Eben Grace in the early 90’s.” That is consistent with the archived history, which names only Michael as the original designer: early contact pages list Eben Grace for marketing and dealer enquiries and Michael for engineering. We give the company’s current wording and the 1990 and 1994 dates side by side.

The company began in Boulder, Colorado, where its contact pages placed it from at least 1998 to the mid-2000s. It later moved up the road: by 2020 its contact page gave a mailing address in Lyons, and its jobs page, updated in April 2026, says “our shop is in Lyons, CO,” a small town in the Front Range foothills about twenty minutes from Boulder.

Preamps, then converters and controllers.

The 2004 history claims the model 801 “helped to establish outboard microphone preamplifiers and direct-to-tape recording as a new standard” — the company’s claim, not one we can measure. What is documented is the preamp’s long life. Reviewing the M201 two-channel preamp in January 2009, Sound On Sound’s technical editor Hugh Robjohns wrote that it used “exactly the same preamp design as that in Grace’s renowned 801 model,” and that the original model 201 had been in production for twelve years. He described a 2U box weighing 7.5 kg, with gold-plated switches for the gain controls and sealed relays for the switching, and added: “I know of Grace units in daily use after more than 10 years that still look, work and sound like new.”

The range moved into digital and monitoring. Sound On Sound reviewed the M903 stereo controller in October 2012 and the M905 monitor controller in July 2014, which used the same D-A converter and asynchronous USB as the M903. In January 2017 Robjohns reviewed the m108, an eight-channel remote-controlled preamp with a built-in A-D converter, inspired by the flagship m801 and the remote-controlled m802, and wrote that Grace products “combine brilliant engineering with supreme technical specifications” and “elegant, refined aesthetics.”

Reviewers have tied that reputation to price as much as sound. In his March 2011 review of the M103 channel strip, Sound On Sound’s Bob Thomas wrote that since 1994 Grace Design had built products around “features and facilities that audio professionals need, rather than building what they can to meet a particular price.” Robjohns made a similar point in 2009: Grace products “could never be called cheap,” he wrote, but their build quality, component choice and over-engineering made them cost-effective over a long working life.

The current catalogue adds instrument preamps and DIs for players — the ALiX, BiX, FELiX2 and MOXi — the m303 series of active DIs, the m900 headphone amp and DAC, the m908 immersive monitor controller, the m701 audio interface and Spacebar microphone positioners.

Design and documentation.

Big consoles get the attention, but much of a modern studio’s signal path runs through equipment from smaller specialist makers. The seven companies in this guide each built a name in one link of that chain: summing, conversion between analogue and digital, microphone preamplifiers, or moving audio between systems.

Summing is where Dangerous Music began. The company says it was officially founded in 2001 with the release of its 2-BUS analogue summing amplifier. Its website gave an address in Edmeston, in upstate New York, in 2008 and 2014.

Conversion is central to several others. Lavry Engineering, whose range includes the Quintessence digital-to-analogue converter, gives its shipping address as Kingston, Washington. Crane Song, whose products have included HEDD converters, gave its address as Superior, Wisconsin, on its website in 2005. Burl Audio, which says it was founded in 2006, makes converters and microphone preamplifiers and describes itself as “based in Santa Cruz, California.”

Grace Design, a family firm that says it was founded by the brothers Michael and Eben Grace in the early 1990s, makes microphone preamplifiers and says its shop is in Lyons, Colorado. SPL electronics, which names Hermann Gier and Wolfgang Neumann as its founders, is based in Niederkrüchten, Germany, and uses the line “Sound Performance – Made in Germany.” DirectOut, from Mittweida in Saxony, works on the networking side, with MADI and audio-over-IP converters and routers that link consoles, stage racks and computers.

This guide sets out what can be checked about each brand — who founded it, who owns it, and what it says about where its products are made — and marks clearly what rests only on the company’s own word.

Built to last, by its own account.

Grace Design remains independent and family-owned, by its own description, and we found no record of a sale or outside investor in the sources we checked. On manufacturing, the company says its gear is “designed and assembled in Lyons, CO” and that “every single piece of hardware we create is proudly built in the USA by family and friends in Lyons, Colorado.” We give that as the company’s claim; we have not seen an independent report on its production.

Its design philosophy is set out in an archived page from 2015. Grace said its microphone preamps were fully balanced, with transformerless inputs and outputs, input stages built on low-noise instrumentation amplifiers and gain stages using “current feedback” amplifiers, and argued that integrated input stages could now outperform discrete designs. Some newer marketing copy on its website speaks instead of “discrete” circuits, so we rely on the engineering page.

The brand’s other promise is durability. It offers what it calls the “EON” 20-year warranty on most analogue-only models and five years on everything else, saying it wants its products to stay “out of the landfill for many years.” Sound On Sound was already noting a five-year warranty in 2009. A domain note: the company’s website at gracedesign.com also carries automatically generated question-and-answer text that confuses it with unrelated businesses, including a design and construction firm, so treat those passages with care.

For a design guide, Grace Design shows how a small maker can build a reputation on understated, long-lived hardware and a warranty that says so. Compare Benchmark Media Systems, another American converter and preamp maker, and Bricasti Design. For this guide we use navy, silver and an ochre accent with a sans, an unofficial interpretation; no product or logo is reproduced.
