I think we need more details about that quick demo if anyone can actually use it for any idea of what is on offer. Was the Amp fully warmed up? It looks like the internal DAC was used with the cable going into the USB slot, what software was used as the player, and what tracks were used? Looks like Tyll admits the demo is almost useless and he needs more time. He needs to have HIS choice of tracks and at least an hour IMO to get a handle on the SQ. Also I find my 009s need a decent amount of volume to come on song as well, so if the usual volume control and track restrictions are applied by Senn again, that would affect the demo as well.
It would be interesting to know if the boundaries of Stat tech has been pushed further albeit with no budget constraints.
