@laaudionut that's good advice. If you can't visit a good dealer w/ multiple streamers, I suggest searching the archives for RECENT threads. This has been answered in gory detail 50 times or more in the last year. They'll all boil down to Raspberry Pi variations and better Intel NUCs for the diy-inclined, budget blusound boxes for low cost simplicity, then stepping to SGC Sonictransporters and Sonore Rendu variants for those looking to leverage large libraries maybe with NAS. Bigger budgets will look at Innous Zen, Aurenders and Lumins. Read up and match your budget & priorities and chances are probably your answer is gonna end up being one of those mentioned above.
Cheers,
