All wall plugs in the UK have the cord coming out pointing towards the ground... it's just a safety device so that you don't pull the plugs out by using the cord. I've just realised that very few people in the US will have had the experience of accidentally treading on an upturned plug barefoot... it is a unique moment of agony followed by three nasty little bruises coming up on the sole of your foot.
Can't imagine the design has any impact on audio quality at all.
