Amp - preamp or integrated

If you buy a sub that's capable and has speaker level inputs (binding posts) then you connect it to your Rogue's speakers terminals along with your main speakers.  Simple way is to use whatever terminal type that is the opposite of your main speaker cables.  I use spades for the mains and bananas for the subs. 

It is so complicated, because there are many good options.
I think this really boils down to what kind of an audiophile are you going to be? Can you find 1 piece of gear you are going to love and stick with for years, or are you going to buy, and keep thinking about equipment for the rest of your life?
If the latter, separates are your ticket to constantly comparing, upgrading and tweaking. If the former, an integrated is the way to go assuming your speakers are a good match.

So far I had my Vandys 2 sig for over 4 yrs. It seems im ready for a change or at least would be open to listen to others. Heard good things about the magnepans. They seem to require a good source or current which my Rogue CM did not supplied. So my dilemma is how much of my current equipment will I change. Is a good situation, albeit a stressy one since there are so many options. I believe that I should start with knowing how much of a budget I will have and going with amp/ preamp. Then if I like the way the vandys sound, keep them or then go with a dofferent brand. Too many x and Y.

you need sufficient room for them

??? Not all mono blocks are monoliths. 

Thisall depends on your budget , a sound ruleof thumb 
less then 25% of the piece of electronics goes into the build,the rest overhead and dealer markup.  A  great integrated has several advantages  such as 1 less pair of interconnects, power cords  and seperate wiring . My brothers Gryphon Diablo is a Perfect example of excellence. There are many excellent integrated amps 
from Denmark  my $6500 Gato 400S was a steal and can match seperate ofmuch more monies.  Pass Labs make a very good integrated in their new line . What is your budget $6k $15$?
please remember respectable interconnects and extra power cord 
is probably $1500-$2k alone .itisthe Parts Quality thst counts .
ifunder $10k the Pass Labs Reno Hifi sells demo,or open box with a full warranty and save several grand.dependingon your Loudspeakers efficiency . Pass has high power, as well as low power models let others know  about your speakers to help you better .
