Best model for vocals only from Anime?

[Z-Editz]

Trying to extract vocals only from some of my favorite shows to make my own fan edits.

Looking to have no sound effects, no background music, and most of all to not have to voices muffled up and incoherent.

Ive tried using kim vocals 1 and 2, but they dont sound great.

Does anyone know which models or settings would be best for what im looking for?
