fogrider,
what frame and fork are you working with here?
as mentioned, the DA calipers you are using have some of the most generous clearance of the short reach calipers. you're unlikely to buy much more clearance with any standard dual pivot brake, but maybe.
There are a few, but most frames designed for short reach "standard" road brakes will not clear 32's. Add to the confusion that many currently available 32c labelled tires are not all the same size/shape. some are taller and fatter than others, which add to the clearance issues - meaning, one brand 32c tire may fit and another may not.
can you take a picture of your set-up showing where the rub is? also showing the position of the brake pad holders in the caliper arm slot?
to clear up the other issue you are confusing, there are a bunch of frames/forks designed to use mid reach calipers and 700c rims. these gained popularity for a short time before disc brakes became common and allowed for a road bike to use fatter tires. Mike Zank, i think coined the concept of the "Road 32" frame. But that's an initial design issue, and if your frame is designed for short reach brakes, that's what you need to use, as the location of the brake track with respect to the brake mounting point is a set, fixed distance (reach).
