Welcome!
I had an HK receiver that I enjoyed very much. The Rogue stuff should sound similar (warm), but they generate heat (a consideration if you live in warmer climates or without air conditioning), and weigh a ton (you may need a friend to help fit it into a rack).
My advice is to pick out the speakers first, then an amp that matches up well to it. Speaker selection is a individual decision (each present/voice differently) but care should be taken to fit the speaker to the available space. Most "over buy" speakers for the given space. If the space is small or awkwardly shaped I'd recommend a 2-way monitor, adding a subwoofer later as needed. If the space is shared setup is probably compromised, and listening time/habits probably limited, so don't over invest. When I knew I'd have a dedicated/nicely designed listening room I invested heavily (for me) in commissioned speakers, then shopped for appropriate amplification.
Personally I'm not a fan of MTM designs as you must sit in the exact middle height of the mid/woofers to avoid phasing errors. And not a fan of passive crossovers in general, especially multiple/complex ones. I listen rather near-field (about 6 feet away) so coherent sound is vital, noting that some of the speakers on your list sound much more "disjointed" than others. So in my opinion it's hard to justify more than 2 drivers per cabinet. Some emphasize the cabinet finish, but that can get very expensive and can easily make the rest of your furniture look downright shabby. And many floor-standing speakers are too tall for critical listening from a low seated position.
But there is no substitute for auditioning speakers (ideally at home in your own room and with your own gear). Use a wide selection of your favorite well recorded albums and take your time. Note taking is a great practice to force your concentration and make up for human failings in our aural memory. Keep in mind that bass reacts differently to mid/high frequencies in-room so generating bass separately has huge advantages.
Take care and all the best to you.
