" the Vandy amps ( M5 and M7 ) have 128v DBS...."
That may be so but I tried 144vdc and it washed out the sound on all my DBS cables. The best tweak is to remove the battery packs from the cables. I place them on Walker Audio resonance control discs which solidifies the soundstage. I imagine the internal power supply on the Vandy amps would have a very similar effect.
