Shame about the cable, I was hoping it would be a DIY job via a CD but hey ho c'est la vie.

RHurley - I'd heard of one, but first actually heard one in Harrods as I was down in London and happened to be killing a few hours.

Tbh I thought it sounded crap on the crowded shop floor and I certainly wouldn't have brought one based off what I heard. It's a shame as I suspect many people wouldn't have gone to the bother of trying one at a dealers.

Any ideas what/how the DSP does its stuff?

I've seen a few videos about the benefits in terms of the speakers, but I'm not clear how much "on the fly" trickery is being done?
