BlueSound is the brand many people begin with. You can get a combined streamer / DAC. I’m sure many folks will jump in on this.
You can get streaming to sound as good or better than any other source depending on your investment level (provided you choose carefully). There are huge advantages as well… access to millions of albums for a pittance. Qobuz is the best source.
For the hardware long term, my rule of thumb is $ streamer = DAC = preamp = amp < speakers (again, heavily researched and carefully chosen). Separate streamer and DAC. The high end / audiophile stuff starts at ~ $5K+. Very substantial improvements in sound quality occurs in DACs through $10k and in streamers throught $15K assuming you have appropriate ancillary equipment.
