I have owned the PAP Horn1s and currently have the Tekton Encores. Both are truly excellent speakers. I know it's an old audio cliche, but these speakers have very different strengths. Your preference may well depend not only on your taste in music and your sonic priorities, but your room and the associated equipment you plan to run with them. The only way to really know for sure is to audition them, though I know that is easier said than done. The Horn1s were outstanding, but barring any unforeseen circumstances, the Encores will likely be my last speakers.
No experience with the Devores.
