Kublakhan, are you out of your mind? "This" will never go with "that" unless you enjoy the shrill screaming of bands like Rush.
The biggest problem other than your obvious complete ignorance of this entire hobby, is your equipment rack. The cables you mentioned will never work with a rack like yours. I would suggest you spend some time in the gym and work on that rack.
Your budget is meaningless since you must be prepared to spend at least 50% more than you have budgeted for any piece of equipment.
A big issue you have completely failed to take into account is the aesthetics of a system. It really doesn't matter what you buy since everything sounds the same, but cheaper gear always sounds better than more expensive stuff. The only issue to consider when buying is whether the new piece looks good with the old junk. It is critical to a pleasant listening experience to have gear that is coordinated cosmetically. Make sure you do not ask your wife for any help since all women want to be dressed by men anyway (otherwise why would they buy their clothes from Calvin Klein, Georgio Armani, Joseph Abboud, and Gianni Versace)!
All things considered, you are barking up the wrong tree.
