Image is blurry Safari, but crisp in Firefox

In working on this website - http://domstroy.kz/ - I have noticed that the logo image that was sized down with the use of CSS width parameter is appearing crisp in Firefox (35.0.1), but is a bit blurry in Safari (8.0.3 version). (Screenshot attached)

Am I doing something wrong causing the logo image render blurry in Safari?
