Should I upgrade my Isotek EVO3?

I’m looking at the Chord S6 or even M6. Would this be much of an upgrade in peoples experience?

System is now NDX2/TP/Passlabs XP12/XA25/Harbeth P3ESR XD/REL Classic 98.

@ameads I went from a $1995 Isotek (I don’t remember the model) to the $5000 Isotek Sigma 5 and found that to be a very significant improvement in noise floor reduction and SQ. I would also change the tp power supply to Naim.
