There are a variety of higher sensitivity brands that are great. I know the Rockna. I don't know the Enleum.
With 25w, Klipsch, Zu, Tekton and Cube Audio would all be brands I would look at. Zu and Tekton are direct. Whether you go new or used would dictate what models to look at. I would do research on those 4 brands and I am sure others people will recommend.
I have no relationship with any of these brands.
