DALI MEGALINE AMPS & CROSSOVER

I have recently purchased a pair of used(2nd owner) Dali Megaline speakers for a can’t pass up/ridiculous/unbelievable/put a smile on my face low price. Being a fan of ribbon Apogee speakers(currently own Studio Grands) I have high hopes for the Megalines since are more dynamic, taller & do home much theater better. I have a 100” projection screen but need to upgrade to a 125” because the gargantuan Megalines make the 100” small!   Anyway, I’m in need of some advice on what crossover & amps to use with them. I tried the Dali x-over but don’t like the sound of the x-over point of 1200hz along with a shallow slope. So I’m using a Beringer Ultrapro24/96 x-over right now at 800hz at 48db. But I know I can do much better than the Beringer or should I have the Beringer modified?!. On the amps right now I’m using digital(Merrill Veritas 400watts) on the woofers & Coda S5(class-A 50watts) on the ribbon. Sounds amazing already! But I know it can sound a lot better but don’t want too(can’t afford!) to spend more than $15-$20K. So, first please guide me in the right direction for a quality 2 way or 3-way x-over under $2K. Right now I’m looking at the DBX Venu360. I really want to do better than that but not sure what is out there for that price. Then for the amps, I really like & think a pair of stereo PS Audio BHK Sig 250 would be awesome! Being they are tube input(sweet sounding) & solid state(punch you in the face) Mosfet output! They have been getting fantastic reviews. Or maybe 4 of the new Benchmark AHB2 ran in mono, or a pair GamuT D200i’s, or should I get two more Merrill Veritas mono amps, so many possibilities! I want amps with balls(home theater) & also sweet sounding(I love music!). I’d rather stay away from all tube amps also due to hat issues here in hot NorCal. BTW- I also stuffed EACH cabinet with 3 pounds of Acousta-Stuf due to lack of cabinet damping. I really think these are going to be my dream speakers for a very longtime. Once properly setup I may never leave the house again! : -) Any & all suggestions would be greatly appreciated! Thank you!!
