Digital So Good, Only An Analog Expert Could Make It Elegance. Precision. Heirloom Build Quality and State-of-the-Art Performance. These are the hallmarks of Brinkmann Audio. Now, thirty years after the introduction of their first Digital-to-Analog Converter, Brinkmann Audio proudly introduces "Nyquist", the world's most advanced DAC. Authored by the newly expanded Brinkmann design team, "Nyquist" sets new standards in convenience, sonic excellence and lasting value. Although Brinkmann is justly renowned as a designer and manufacturer of State-of-the-Art analog components, the company's first DAC, "Zenith", debuted in 1986 and still enjoys a devoted cult following. For Helmut Brinkmann, the development of "Zenith" demonstrated the importance of analog circuitry and passive filter implementation in the design of high end digital components. Everything Brinkmann learned with "Zenith"-combined with three decades of subsequent engineering experience-has resulted in "Nyquist": the culmination of our vast audio design expertise. An entirely new design, "Nyquist" has been optimized to accommodate the latest digital formats including MQA™ (Master Quality Authenticated) streaming and playback, PCM up to 384 kHz/32 bits (including DXD)as well as DSD 64 and 128. Given that future formats will inevitably appear, both the Hardware and Software of "Nyquist's" Digital Module are easily user-replaceable. This field-upgradable architecture assures unprecedented longevity and enables "Nyquist" to remain on the cutting edge of digital technology. "Nyquist" virtually eliminates obsolescence, making it audio's first-and-only "Investment Quality" digital component. Proprietary high voltage power supply technology-unique among digital source components-delivers marked improvements in digital circuit performance as do custom filters in the digital domain. In a nod to Brinkmann's renowned "Marconi" Line Preamplifier and "Edison" Phono Stage, the "Nyquist" employs hybrid circuit topology, with tubes used in the output stage due to their instantaneous response to voltage changes. Because today's music connoisseurs demand the ultimate in convenience and versatility, "Nyquist" offers outstanding connectivity, including USB, SPDIF, Optical and Ethernet inputs. Balanced, Single-ended and Headphone outputs are all standard. "Nyquist" offers RoonReady™ network playback and music management and supports several streaming services while optimized, pre-selected filters have been carefully tailored for every digital format. A comprehensive remote handset offers control of volume, input selection, mute and phase. Thanks to our obsessive attention to each of these details, "Nyquist" achieves a level of user-friendliness unprecedented in High End Audio. Given its ease of use, matchless craftsmanship, total upgradeability and, of course, sonic superiority, "Nyquist" is simply the finest digital component available today...and tomorrow!
