Dad likes my Infinity Kappa8's, What's similar?

What's similar without the headache? I wouldn't wish the amp compatibility issue on anyone. My father downsized his system drastically when he retired. He's ready for floorstanding speakers again. I am trying to build him a simple system, starting with the speakers. His room is large, but there is little room for speakers or componentry. Narrow profile is important. He likes vinyl. Musical tastes include Rolling Stones, Bob Dylan, Willie Nelson, etc. The system should rock tightly. If I could, I'd get him set up with Monitor Audio speakers and a Musical Fidelity integrated amp. The budget is just too modest for that. Looking for suggestions on speakers primarily, and amps secondarily. Thanks
