@erik_squires I am not in the market for a set of digital powered speakers at this time. I put out the question because I didn't understand the "inner machinations of HiFi" such as jitter and so on. Slowly, as I read these posts, I am learning. It would be a game changer if the difficulties could be fixed.
Copper vs Optical Fibre
Can anyone answer me (especially the equipment manufacturers) why copper connected components can have signal clarity and capacity to 32bit/768kHz, DSD 128, 256 etc, while optical fibre connections (toslink and the like) are restricted to 24bit/96, DSD over DOP, PCM if you are lucky to them up-sampled. In Australia, the National Internet being rolled out has very high up/download speeds on fibre is you can get it, and lousy speeds on copper. Why is optic fibre not used more extensively (between components and speakers if possible) as it does not suffer the maladies of copper connections?
