Its not a good idea to parallel coupling caps. Different caps have different 'speeds' on account of their dielectric constants. The result smears the sound- that seems the best way to describe it.
You are always better off just giving it your best shot with the best cap you can afford. V-Caps are some of the best out there. Do give them some time to settle down.
