I don't understand why people buy external clocks. The dac itself should already come with an excellent clock. Not sure I like the idea about adding an additional box to address a deficient clock within a dac. Plenty of higher end dacs have excellent clocks. Maybe you're stuck with a deficient dac that should be replaced.
I don't like separate dacs and I have a couple but I purchased a lumin x1 which is a streamer/dac and that's working out really well. I don't have to fiddle with extra connections and tormenting myself with a feeling I need to consider a new dac. Also the internal wiring if done well to connect a really good dac capability is far superior than dealing with additional interconnects, etc
I'm not a fan of integrateds, but in these couple of areas above it would seem to me justifiable
