Yes true, they are supposed to be ok in corners, I just thought I'd play around with positioning a bit, its much easier now that I've swapped the room around, they used to be on the other wall, but now I have a bit more space around them, it sounds better overall before I'd even started repositioning, they may well end up going back in the corners. The mission cd player is actually quite smooth, it has a decent chip - the classic one - tda whatever..... I quite like it, could may;be do with a service. If its a distortion issue then its probably not the amp, as it sounds the same with the Soro amp, I am looking into getting the speakers checked, I'll also plug in my other speakers some time soon to compare.
