I imagine there are products designed for signal amplification or conversion that don't require compute. I'm curious why you chose to use a Raspberry Pi? I assume it adds compute power, providing new functionality, but it's not excessive in terms of compute. Is my premise correct that there are products for signal amplification or conversion that don't need compute, and your product is unique because it includes a compute element? What does that compute element add, and what would be considered too much compute?

From the HiFiBerry perspective, looking back 10 years, technology has changed significantly. Our product does offer some compute, but it's more than that. Even if you have a board for digital-to-analog or analog-to-digital conversion, what do you do with the signal next? It's not just about compute. In our case, the signal processing is done on our board, with the CPU being low lift for us. The Pi isn't just running the operating system; it's also handling input and output. At a $45 or $55 price point, having compute along with an OS substrate, kernel layer, input/output, and extensibility is versatile.
