Hi, Realised the other day that I still had 1.78 and not 1.79, so checked around and read all teh details of differences and got Arcam to send me out an upgrade CD (I am out in Germany at the minute). In the meantime I had gone in to ask at my local Arcam stockist who checked around and told me that there are negatives and positives to the upgrade and said it was up to me whether I wanted to do it. Anyone out there know what the supposed negatives are to this upgrade. Has everyone else upgraded??? I have checked out enytech and there are no details of any negative impacts. Thanks, Dave.
