Sorry for not posting my results with the Supra 3.4s cables sooner.
I was using some Nordst spellbinder cables (solid core). Putting the Supras in brought the vocals to a new level. More even up and down the audio spectrum. More cohesive, and a wider and deeper soundstage. The difference wasn’t night and day, but it was discernible.
I’ve now put a Primaluna Dialogue Premium integrated into the amp position and the entire system sounds fantastic.
Though, I might just try the Audio sensibility cables, you never know
