I've yet to hear anything better than Devialet - the D200 is spectacular, the D400 better and the D800/1000 genuinely world class. For real world budgets the D200 is light years ahead of anything else. The sound has resolution and detail equal to the very best (Solution and Boulder) with perhaps even better bass. The musicality and PRAT are again reference class. All in all, the sonics are without reproach. Then you factor in the cost saving without an ugly mountain of separates and all the power cables and interconnects you no longer need. Then there's the configurability and ease of use. Full and complete sub-woofer integration better than a standalone JL Audio CR1 as well as SAM speaker matching with bass time alignment. You can pretty much control it all from ROON over wifi. The new 220 Pro is even better.
The Parasound isn't even in the same league.
I leave mine on 24/7, sat on a granite slab on Cerabase feet. Devialet air will run on Windows or OSX and does need a strong wifi - or Ethernet. USB is pretty damn close but I hear wifi ( no galvanic connection/jitter) as the best of all three. Powering my Focal Utopia 3 Diablo's with JL Fathom subwoofer, it's damn close to perfect.
One Wireworld Silver Aurora 7 power cable and a pair of Analysis Plus Solo Crystal 8 speaker cables - simple and done.
