Best Placement - CT-1E

I am re-assembling my rig after some renovations. I have two pairs of IC's for placement decision: the HF CT-1E's and JPS Aluminata. One pair from DAC to Wyetech Opal pre, one pair frompre to Krell FPB 300cx power amp.

Peviously, had HF's from DAC to pre; JPS from pre to power amp, and sounded grand. Should I swap them? Yes, I know I can listen, but I am asking for your thoughts. Swapping cable placement is such a huge hassle in confined space.

Thx.
