Have you considered adding a sub? When set up properly it will add to the sound stage and bring out the lowest octave the S1.4's can't reproduce. I have a Rel B3 with my C1's.
Another thing to consider would be to replace the Parasound with a tube amp. I have an Octave V70SE and at 70w/ch it is plenty for the C1's.
