firedog, are you sure you don't work for Olive ;-)? Great response to Eloise's question that I couldn't have phrased better myself.
DSD support would be phenomenal, but you can understand its appeal is not too widespread, and given the $399 price point we're limited in terms of how many features we can realistically pack into the ONE. If HD music is what you're interested in, the ONE's built-in Burr-Brown DAC can handle up to 32-bit content.
