Me got charcoal (black) one too - 4 series. Looks great even when switched off.
The technical justification (if anyone is interested) was supplied by Joe Fernand - the silver screen's 'bezel' round the edge is shiny, and its shinyness reduces the perceived contrast. A charcoal bezel does not detract from the screen's contrast.
I haven't explained that brilliantly.....
Also, I avoid 'silver' components because they're all different colours. Arcam silver = gunmetal grey for example! I go for BLACK.
