Soundstage is wide and enveloping with the DCM's due to the design having both direct radiating drivers (the inside face of the head unit) and dispersion drivers (the outside face of the head unit) Soundstage can be shaped using the three controls on the back of the head unit: Tweeter Level, Mid Frequency Dispersion and High Frequency Dispersion.
Between iTunes and RuneUI, I'm cheering for Rune!
One noticeable difference between iTunes and Rune is that the Volume control in Rune whether MPD based or mapped to chip hardware by alsa, has much finer stepping than the control in iTunes. The Rune volume stepping appears to be linear all the way down to zero volume.
