(Hegel vs Luxman) vs PS Audio

My other components are ps audio latest transport, Dac (for Sacd), p20 power supply, mola mola tambaqui for cd, streaming, Synergistic Research all Galileo SX interconnects and Power Cords, SR active Ground block, Lumin streamer with separate lumin power supply, Focal  Scala Evo Utopia.....

Looking for more soundstage(though it's pretty good now) just improvements (width,depth); more impact. 

I like soundstage definition and impact - (not just in base) and detail, lots of detail. Coldness should not equate to detail though. 

Big fan of Luxman, but these are relatively easy to drive speakers.  The stereo units will do just fine. Another amp I think would do really well with these is Ayre.  They may complement the treble balance.

That helps a lot, but what are your room dimensions and how do you have your speakers set up in the room?  Also, what room treatments, if any, are you using?  You have good equipment and many of the things you’re looking for can be greatly affected by things like speaker placement and room treatments, and a lot cheaper than buying new equipment.  @erik_squires can give you much better recommendations on room treatment, and I agree with his frequent recommendation on consulting with GIK for how to maybe treat your room.  

So room is the "Elephant in the room". Open concept speaker fronts 4.75' off back wall, ceiling sloped then flat at 14' high, room primary depth is 23'. Part of right side is intermittently open. Just complicated. Speakers have been dialed in using PS audio set up. Super detailed, clean, real nice soundstage l to r , descent f to r.. mor source dependant. I have some panels made with help from Acoustamatic. About the limit of WAF. The room is the family room. My biggest issue is I have yhe balance at 3% to right to help the sound stage (open side). My sweet spot is great, but move 6" r or l and it drops off. Speakers are towed in a little less than Focal wants. 

I forgot, also is my home theater using pass-through on Bhk preamp. In stereo and HT I have 2 REL 810 subs one left one right.
