I think I would change speakers,IMO the 15 year old silk tweeter is hiding low level detail & resolution..Advanced coatings & materials put today's speakers wayyy ahead of those that are well over a decade old..Since you have AVR,YES to a CC speaker..Ask V.S.about matching if you stick with them..you could try "brighting"up the room(harder more reflective) which would help with dialog but kill tonal purity..
Another option & one I highly recommend is adding a good,tube based headphone rig...The listening perspective is different but the low level resolution & detail with the right "cans"brings music to life in a way speakers can't,but then the same can be said vice versa...
I hope I have the same problem when I'm your age.At 59 now with the life I had I'll be thankful to make 70 hahahah...
