At least people in this forum believe DAC is a problem that has already been solved. If you see it as a tool for converting audio signals from digital to analog world, then I don't think there will be a DAC that can excite anyone again. Can you imagine being excited about a new screwdriver or a hoe invented and produced this year? Even for DACs with rich features like the ADI-2 DAC, most of the functions are already perfectly solved by software for quite long. People are still constantly reviewing new products of course, but I always feel that the purpose of new products is just being "new product" so people are willing to buy them, or as a replacement for old or broken ones, not because they have provided any new solutions to any problems. So do you think whether there will be a DAC product that can excite you again in the future? If there is, what kind of DAC do you think it should be?"
For me, I think it would be interesting to be able to load VSTs into the DSP for audio processing, similar to Apollo's audio interface. This way I can simulate various distortions, or use plugins to achieve functions similar to spatial audio. But maybe it doesn't solve any problem either, because loading VSTs in DAW software can also achieve this and sometimes much better and more convenient. Also multi-channel DACs are very useful, and perhaps ADAT interface expansion can be considered on the DAC, such as developing expansion modules with multiple digital interfaces or multiple analog interfaces. Each type of module can be purchased as needed.
