I would fully agree with Kunter although I have no personal experience with both the Entreq devices and the dual mono Devialet setup so I can't "rate these". Also I would like to add 'acoustics and optimizing loudspeaker/listening position' up to the highest position on top of the list.
0. Acoustics and optimizing speaker/listening position
1. Decent source. Either spend on a dedicated/optimised pc solution or if you have the means, something like the Totaldac Server... If you go with PC, dont use it for anything else, and connect with direct ethernet.
2. Power line upgrades. Includes power cables, conditioning, dedicated line.
3. Speaker cables.
edit: and of course I don't know anything about your acoustics, these already could be alright but I do find that your loudspeakers are spaced rather far apart, into the corners, because of the wide furniture in between. It does look really good though!
