Bottom line is that this system is for "dad" who is not likely an audiophile, else he'd be setting it up himself. With some folks esthetics, convenience, whatever far outweigh imaging, purity of tonal balance and the rest of our arcana.
My advice is to make sure that the system is safe - the hooks have adequate safety margins, the cables don't get tangled with the raising/lowering, etc. - and then let your dad enjoy it.
