is it possible to bypass the up sampling concept for DSd and do a simple filter as some dacs do for DSd only. ???
As some feel pcm is very good and DSd is nice but can still be improved upon.
The dacs I have heard do DSd the best are what is called chip less. Now I do not claim to know what that even means other than the sound it produces is really good DSd.
As your always looking for new ideas to improve the DS dac is this a possibility ?
