Horns & tubes rule, my friend. I once had Mac solid state (sand)amps on my K-horns & Cornwalls... not bad, but a bit harsh like you described.
Remember w/ K-horns, the first watt is the most important, actually the milliwatts leading up to the first watt. Solid state amps specifications are rated at full power & not very low output levels. That's where they suffer.
I would check out low powered triode amps for the ultimate sound for your horns.
I wouldn't go the ALK x-over route. Bob Crites makes awesome original crossovers (Type A & AA) from Paul W. Klipsch orginal specifications. I just hooked up a pair & they sound very, very good.
Good Luck, have fun & enjoy!
