As others have said, it isn't a crankset issue, it's an FD adjustment issue.
My guess is that when you changed cranks you didn't see the need adjust the FD, because it seemed fine as is. However the new cranks are probably a smidgen more outboard than the old ones, making the FD adjustment off. You should do a proper FD adjustment any time you change cranksets, but in your case you might bet by my trimming the inner limit in a bit to bring the FD out more at it's innermost (low gear) position.
