I concur with all that has been said about this topic. Yamaha use to put these ohm switches on their AVRs which was a waste of space, accomplished nothing in the process and just confused the owner. Reviewers constantly complained that all these switches did when set to a lower ohm level, was restrict the power supply.
Over the years, I have outboard power amps and tried both bi-wiring and bi-amping with many different speakers and quite frankly, if there is any difference in the sound quality, I have yet to hear it.
