In my opinion we are trying to out a square peg through a round hole. I would recommend a system turnover which my require obtaining some used equipment here or on the other well known sites to get you speakers and a system that can do the job you want.
You mentioned your dream speakers were Vandys at $8400. For a fraction of that price you can get the Magnepan LRS which I heard At AXPONA and are a flat out deal at $650 or the .7i or 1.7i (which I own). If you get the .7i or 1.7i, then for less than $600 you can get the MyeStands which will improve dynamics and bass. I used to use a sub with my Maggies. Since the MyeStands, I am selling my subs. For the LRS you may need a sub. Get a small sealed sub. REL or Rythmikaudio. As for an amp, get a used solid state relatively high watt class AB or low watt high bandwidth class A stereo or integrated amp. For Maggies, I prefer the former. If you go with a higher sensitivity box speaker you can go with either. What ever is cheapest but good. That is where the most money is going to go. You may be able to keep the Mani and Saga. But those will be the weak links in your system. Sell the Behringer and Vandys. Yes it’s a partial system overhaul. Welcome to audiophile land!
