Have you considered the Masters BoX? I think this would be an excellent match. It’s parallel single ended but has the ability to handle tougher loads without much if any issue.
I dont think your speakers would be a tough load on a tube amp. The impedance has a bigger impact on them than the sensitivity as it taxes the transformers far more.
