Had an old Radius flagship from years ago, and really enjoyed the sound then. Probably bought that one from Dimitri. Not sure if the sound difference is worth the extra $100 between the TWF31 and TWF41, thoughts?
carlsanCan't help you choosing between the TWF31 and TWF41, since I haven't heard the former. But I can at least say, that compared to the older TWF11 and TWF21, the TWF41 is a considerable upgrade in clarity and refinement.
