It's not the font itself, rather the letter spacing has been increased. I think it looks good.
The 1px letter spacing is actually a decrease, try toggling the CSS rule off, the letters will be spaced out even further.
I had a play about with the numbers a little, I think 0.5px is probably a nicer setting.
