These days most use a streamer (like WiiM Ultra) and a power amp (like the NCx252MP) as minimalist setup. Integrated amps are or very classic models, or not used anymore. Because with a integrated amp like the DA-S250NC, you still need to add a streamer, that probally has a volume controll, and in the case from the Wiim, you can even connect a turntable and so, as it's de facto also a preamp and dac.
