You'd have to listen to the Salons (driven correctly) - all you'll get here is subjective opinion...
Here's mine based on previous experience: you'll probably find that the Kanta have more pronounced highs than the Salons (Kanta are designed to be flat from one end to the other, the Salons' FR are designed to drop a bit from bass to high frequencies).
I found the Kantas' mid-range detail excellent and probably easier to drive than the Salons. Also keep in mind that the Salons are more expensive.
Both speakers measure quite well by the way and sound like they do.
