>They've fixed this with the mark2's:) (digital noise)

Just checked. Bloody hell, they have. Completely. Player on pause, amp on the end stop, and silence. Given how little time I spent listening to my Mk I play silence at full gain, it's not going to make a lot of difference, but it's nice that it's gone.
(Anyway, all you sound obsessives want to get yourselves a proper car to put it in.. finally found a picture of one of the cars I run the Mk I in, see if this works...)
