Streamer? Aurender's "caching streaming" ? how important is this feature?

thank you, so which of their competitors offer caching?

Heck, my Raspberry Pi running moOde offers "caching". In the options it's called the audio buffer and the max size is 64 MB. For a stereo 24/192 file, that's about a minute's worth of music. It can also prefetch the next song in the queue and put that in memory.

So do most reputable player programs.

PS Audio is about to come out with their next DAC and the man that designed both hardware and software has gone through pages of posts explaining in great detail the myriad of tradeoffs in design.  The number of decisions made are staggering, but when they make a change, they then listen to the results.  It isn't just having a buffer, but companies like Aurender have many years of iteration behind their present product.  My iFi Zen Stream has a buffer, but it isn't an Aurender.

I am expecting the Aurender N200 tomorrow or Thursday and part of the reason I went with it was it's playback from memory.    It makes sense to play streaming media back that way.
