Will post a comparsion on here once I get one, but judging by reviews, I'm expecting it to be a good improvement....
Saying that, I do have a Chord powerchord mains cable attached to my S350, which gave a good improvement in sound and picture quality......will be interesting to see if the S370 is better with the powerchord still attached to the S350...
If not, I will be happy to get i player and BBC HD through it, anyway......(keep the wife happy, anyway!!)
