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

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.   

@oddiofyl  I would love to hear everything you have to say about the N200 once you have it and how you like it, how much better it is than what you have SQ wise. It's on my future upgrade radar. Thank you.

I have a PS Audio PerfectWave MkII DAC which has a buffering and reclocking feature they call a "Digital Lens." I'm not sure what the cashing feature on a streamer would do for me. It might be cheaper to get a DAC with a buffering feature than to get it in a streamer.

BTW, I stream through an ASUS gaming laptop. A FLAC or Qobuz file sounds the same as the corresponding CD to my ears. I partly credit this to the DAC's buffering and reclocking feature. Whatever noise or digital nasties that the laptop is generating are taken care of by the DAC.

I will definitely post my opinion, however my system is a bit hobbled since selling my preamp and putting my old trusty SFL-1 back in the chain.  
 

I am a few months away from receiving my new preamp I’m having built.   Either way I should hear an improvement…..  to what extent I won’t quite find out until November or December
