DAC chips are a rather sophisticated circuit element...
Their output is affected by, among other things:
- the stability and noise in their analog supplies
- the source impedance of their analog supplies
- the amount of jitter produced by the main clock (and how much of it reaches the clock input of the DAC chip itself)
- the amount of jitter introduced by the input circuitry (S/PDIF recievers all have an inherent amount of jitter)
- all sorts of factors that affect the analog circuitry in the overall device
These all produce small, but clearly measurable differences, which also seem to be audible.
Feel free to BELIEVE whatever you like.
Most of that list should be easily addressed through proper implementation.
As to the “small, but clearly measurable differences”, I don’t doubt that either. Can you show any of those measurements so that it can be determine if they are likely to be audible to a human? Since you have an AP 585, there should be plenty of hard evidence regarding the magnitude of the differences. Jitter, for example, is commonly referenced by audiophiles as the cause of audible differences, yet I can’t remember the last time actual measurements of jitter on a modern component were anywhere near the threshold of audibility.
