Spectron MIII MKII after market tweeks ?

Pls share your tweeks on your Spectron MIII MKII power amps.
I know the power cord and isolation devices makes a difference. At the moment I am powering up 3 pcs MIII MKII with PAD Dominus Ferox and installed Finite Elemente Cerapucs.
Each amp is feed on it's dedicated 20 amp 120 vac line.
The results are easily felt especially with more clarity of the bass notes.
I am considering adding the Remote Sense Cables, however, I operate 2 amps in mono and I am not sure if the Remote Sense applies in mono mode and what benefit versus the price of the Elrod cables.

Thank you.
