I have a Bluesound NODE streamer and a Denafrips Are II DAC.
Given your budget, I would suggest that a used NODE (which has a built-in DAC) would give you the most bang for the buck. Especially if your hearing or system isn't top-notch, you'll find the NODE's DAC quite satisfactory, and you can continue to stream via wi-fi--the NODE is really designed to work well that way, and it does when you give it a strong wi-fi signal. The smartphone app for the NODE can also tell you the wi-fi signal strength it is receiving, so you can know whether it is strong enough to stream high-resolution files or just CD-quality files. And I can hear that hi-res files sound better than CD on the NODE, even using its DAC.
