I just got into streaming about six months ago. I bought a new Bluesound Node N130, $600, a better USB cable, $225 and a linear power supply, $475.
It’s hooked up to my router and through the router, to my NAS that has about 1500 CD’s on it. It’s plugged it into an external DAC and the to my integrated. My CD player and Transport ( I have about 1600 CD’s) are also plugged into the DAC.
Total cost is about $1300.
