Integrates combine the preamp with the amp, and sometimes a DAC, streamer, phono stage. Most integrated DACs are made to a cost point and are usually sonically subpar compared to external DACs - this is a major reason to go with separate DAC. Streamers also varies in sonic quality. Maybe a Hegel H400 all-in-one might be a good choice- the DAC is very good. Integrates saves extra costs on casework and additional cabling.
Separates offer easier upgrade flexibility, likely an easier path to navigate to an ideal subjective sonics. Downside- more cables, boxes, expense
