i bought recently the Pro-Ject stream box net. Although it's a decent equipment for its price i'm not impressed from the sound quality i get (sometimes no musical touch and quite electronic). I use a NAS 2tb and all 90% of my files are in flac audio format. My options in the near future (3-4 years) i suppose are two (in terms of cost): Connect the pro-ject to any reliable used external DAC or replace the Pro-Ject stream box for any used higher quality streamer (like Naim). Given the fact that music streamers is a relatively new market i suppose that finding any used piece is difficult of course...Moreover, many people say that a minimum of 1000 euro is necessary to spend over any used good quality DAC in order to hear any audible improvement. So what do you think?
