I have had several Avalon speakers over the years, starting with the Eidolon. I now have the Saga.
Some Avalon models were/are exceptional speakers, with an ability to disappear that allows for a fabulous soundstage, and a seamlessness between the different units that is rarely seen in boxed speakers.
This said, their strategy in the last years is difficult to understand and I also suppose that it is easier to sell speakers in aluminium or some exotic material than in more traditional MDF. As a result the number of agents is small and they seem to be in the process of becoming a niche brand, as others in the high end. Communication with Avalon can also be problematic.
But as XV-1 says the Saga is incredibly good. It has what I would call as a tonal density that can be addictive. Although being a big speaker they manage to disappear in the room and they are not particularly difficult to power. Their tweeter is probably the best I heard. They certainly deserve to be better known.
