But are very high end players. There are probably a few others, since this is a becoming a pretty hot market segmens, as more and more real high end oriented folks are moving away from spinning disc, but are intimidate by the prospect of having to build their own Mac or PC based system.
I don't know the sooloos, but I think some of it's competitive advantate was in the library management and user interface features.
I suspect with the advent of iPads, a lot of manufacturers can put together a very decent user interface, and may be superior stictly from a sound quality perspective, using their latest technology.
