Hello Essrand,
I listened to some Aleph Designs with Horn speakers and it was always a good combination. The recommendation from Stereo5 - ZU Audio - is interesting, too. Another idea is to check Reference 3A, those speakers are outstanding from Performance, or Verity Audio, but I have no experience with their 2. hand pricing. You can also look what Atma-Sphere used for their demos, probably you can get some new ideas there. The Alephs are quite robust with speakers but they are never made for low impedance speaker designs.
