I wonder how much of your experience is the speaker position next to all that equipment tv screen and so on. The normal horn dispersion is getting reflected by the walls and equipment including the tv most probably.
I have a different category of horns, hand turned American maple and a super tweeter set up powered by Luxman M900u, etc. my experience is based on at least a four foot clearance around the horns. A better layout here could improve your experience I’m thinking if you can drop to two shelves or reconsider the locations and set ups. Watching Acoustic Fields Dennis Foley offers loads of information.
That said my horns have never been bright or harsh. Only using an Esoteric K03Xs did I find it too harsh not even on horns and sold that unit. No regrets.
You’ve got two great sets of equipment that might even give you greater pleasure and experience if you can experiment a little. Others comments on certain equipment and synergy factor here too. Room acoustics and speaker positions are a strong part of that mix.
