Answer: Carrots are not terribly difficult to grow, doing well in a deeply prepared and friable soil within a range of pH from 5.5 to 7.0 and with at least average fertility. In my experience the secret to sweetness is in the variety (some are sweeter but it sounds like you have been selecting those already), the age and the amount of moisture they receive while they are growing. You want to keep them growing quickly and when they reach a larger size, cut back a bit on the moisture so they don't split. The quick growth keeps them sweet and juicy rather than woody. The flavor peaks when they turn orange and then lasts for about three weeks (longer in the fall) so keep that in mind, too -- don't leave the early crops in the ground too long.
