Will skinny-leg diode restrict amperage compared to fat-leg bridge rectifier?

Hi All,

I want to do some modifications to my power amplifier, to see if i can hear an improvement in sound...but have come across a potential issue.

I want to replace the main bridge rectifier with zero recovery time SiC diodes.

I have a fear that if i replace the fat-legged bridge rectifier (Image 1 below), with a Cree SiC diode assembly, like in Image 2 below, that the skinny legs of the Cree diodes will restrict amperage, even though the Cree diodes are rated at the same amperage as the fat-legged bridge rectifier.  

What's your peoples take on this?
