Once again:
NO ONE can tell you whether/how your system, room and/or ears will respond to new/improved interconnects. There are simply too many variables.
The only way you’ll know for certain, is try them for yourself.
The least expensive way: contact the guys at The Cable Company and take advantage of their lending library.
For a pittance, you can try a few of their offerings and the rental fees are applied to any purchase made.
In you shoes: I’d try the three Audience Ohno cables, currently available (RCAs/url below), between your TT, DAC, SACD player and Vincent. With new/improved cables, in those critical positions: you should easily gain the knowledge you seek, one way or the other. Even with your current speakers.
Whether to explore/spend further: up to you!
