Buy a cheap DAB-radio with SPDIF out (there are several small, goog looking models without speakers - just analogue and digital out) and plug into the 800 digitally. The sound will be truly awful, but so is a the sound of a high end DAB-card, too I suppose. In my world you can't make 128 kbps or even less sound good. If DAB wins and FM is turned off, we have one high end source less.

Current M-related equipment: DSP7000 (2), G91A FM, Sonos ZP90/ZP80 Zone Players, F80 (kitchen,yellow).
