Check in: How quickly are streamers and servers evolving?

- dac technology is quite stable/mature...very good sounding dacs are less expensive than ever, from chi-fi and other makers -- this brings very good sound to the budget audiophile, and puts alot of pressure on makers of 3-4-5-6 grand dacs on really delivering something superior... they are really making super high quality output stages as in megabuck line stages with excellent circuitry, isolation, parts quality, often with tube buffering to get purity and beauty in tone to go along with the excellent resolution that can be gotten out of the d/a conversion stage...

- streamers are also fairly stable as pieces of equipment, but the key here is that streaming services are still shaking out, and this will continue for the next 5-10 years...each offering new interfaces, sampling rates, higher resolutions, specialized content, each trying to lock each other out from the user’s eyeball range with proprietary u-i’s, dedicated software wrap-arounds (witness tidal connect, spotify connect, and so on) -- this tough and evolving competition creates some level of instability (and risk) in streamer purchases, as these are basically dedicated computers that will need updating when the streamed sources change the game, their interfaces etc -- to me, the resulting indicated action is to buy a good low to mid priced streamer (that sound excellent, btw, so long as proper internet connectivity is provided) so as to keep options open and don’t end up owning an expensive brick down the road that are no longer supported/updated

DAC's: ...have reached the technological maturity...there will not be major changes in the next years, except perhaps the DSD ratio.
SERVERS AND STREAMERS:...just the opposite: you find many different technical solutions rapidly evolving and many commercial solutions trying to cover "everything": you go from "dedicated computers" for storage and streaming to totally separated solutions: server + streamer + renderer
indeed more, you have to consider your "music manager software" going from proprietary and closed hardware integrated solutions (Aurender) to proprietary solutions accepting external ones (dCS with Mosaiq, accepting Roon) to full open hardware accepting "music managers" using UPnP or Roon that is based in a network proprietary standard (RAAT)....comparing what I presently use (Mac mini dedicated and configured only for music) with a basic Innuos...I can clearly hear differences but they are not significant ...with the DAC...the differences were huuuuuge.
My opinion is to wait and see (two or three years minimum) and use a commercial computer or some specific but CHEAP one (Intel NUC, Green .....) or the very basic line of the dedicated hardware solutions if and only if they work with non proprietary software (Antipodes, Innuos, 432Evo, ............) and when market and solutions consolidate and start to be "similar" to spend the big buck.
