Case Study / High-End Audio
A complete DAC/preamp/streamer product design for a luxury audio manufacturer, combining network streaming, DSD processing, and high-performance analog output design.
A luxury audio manufacturer set out to develop a new integrated product combining network streaming, digital-to-analog conversion, and preamplification in a single chassis.
The product needed to support multiple digital and analog inputs, advanced DSD-based audio processing, touchscreen control, and a manufacturable design suitable for production development.
Grinalds Solutions supported the full engineering effort from R&D and prototype development through DFM-focused design.
The design includes digital input routing, embedded control, streaming integration, DSD upsampling, a discrete 1-bit noise-shaping DAC stage, precision analog filtering, analog volume control, and a diamond buffer output architecture.
Digital inputs including USB, HDMI, coaxial, and optical are routed through a controlled input architecture with a custom touchscreen interface.
The audio path upsamples incoming digital sources to DSD before conversion through a discrete 1-bit DAC stage. The analog chain includes transimpedance conversion, Sallen-Key filtering, analog volume control, and a diamond buffer output stage. Analog RCA and balanced XLR inputs are also supported.
Grinalds Solutions completed and delivered alpha prototypes that bring together streaming, digital audio processing, analog input handling, DAC conversion, preamplification, and user-interface control.
The project has progressed from R&D through prototype delivery, with a DFM-focused architecture intended to support the manufacturer's next stages of product development and release planning.
