Roon's 64 bit floating point volume leveling

Usually, there is enough extra headroom available to make quite a large adjustment without losing any precision. The 64bit number isn’t really involved in this discussion, because it is never the bottleneck for precision. There is always a smaller precision bottleneck somewhere between Roon and the DAC–typically 24 or 32 bits. Very occasionally there is a 16bit bottleneck–but this is limited to very old or very cheap devices not marketed at audiophiles. Lets say you’re starting with CD quality…
