Does bewiring decrease "wholeness" ?

An audiophile involve in audio sales once told me, that to connect my speakers using its bewired option instead of the jumper with a single run of cable, will reduce the sens of "wholeness" that I am loocking for.
It seems, that doing so, mite encourage some disparitys in the process, so as to reduce some of the unitary ingredients responsible for the beleivebility and cohesiveness of the "one event-many participants" I am listening to.
