Given that you have Krell amplification which is brilliant but it is a hair forward of neutral, I find some of the suggestions hear fascinating. It sounds like you prefer a slightly forward sound profile, but some of these combos might end up being a bit fatiguing.
If I were you, I would look at the Spendor D9s. I think they would be a brilliant match for your amplification and should meet your needs in terms of looks. It is a natural sounding speaker that I think would really come to life with your electronics.
I don’t have them available for Demo but they should be easy enough to find.
Another option that you will either love or hate is the Scansonic MB6 B. Sound is to die for but looks are not for everybody. I heard the side-by-side with the Magico S1s and they blew the Magicos out of the water. The MB5 B has broader appeal aesthetically.
