have only heard of the kenwood brand, all the others are not familiar to me. I would do research to see if you can find out who actually makes these components.
Genesis makes very well built, high end components. I run one of their amps and love it, and it is their "entry" level line. And I have had PPI, Xtant etc etc. If you are going to pick up a sub I would have a look at their component sets as well.
And to be honest you are piecing together a very solid SQ system, and what is likely the most important piece, the headunit, is your weakest link. I would personally look into something else other than kenwood. Burr Brown DAC's should be something that you look for. Check out Eclipse or the Alpine w201 IMO.
