Computers fail, there’re noisy and take up space. Streamers provide absolute simplicity.
Streamers are computers
Streamers like the Aurender mitigate timing errors in the signal transmission by buffering, but this only limits the signal jitter.
rubbish. All streamers send packets of data. The DAC unpacks these packets. Any "timing" in the streamer is ignored by the DAC because the timing/jitter in the DAC is completely unrelated to the timing in the streamer and the switch. They are not correlated. Have fun spending big $$ on expensive clocks in streamers and switches, just be aware these timing signals from these expensive clocks do not affect the timing in the DAC in any way.
That said, if you don’t hear a difference, then please share your experience comparing the 2 approaches in real life.
Without wasting your time with the details. I’ve tried a LOT of cables, power supplies, switches, reference clocks , streamers, re-clockers, and so forth on the devices to feed data to my DACs. My experience is if you have a quality DAC.. all that stuff , like many other things in this hobby, is a complete waste of money. Like many other things in this hobby, many hear an improvement every time they spend more $$.
