I just did a similar test by connecting sets of cables to A and B outputs and then to the speakers without removing jumpers. I am able to just flip the switch on the amp from A to B and back in real time and not disconnect and reconnect the cables.
Cables are 14 foot pair of Synergistic Research Resolution Reference and a 5 foot pair of Kimber 4VS doubled to make them 8VS. I have been using the SRs for many years since getting them with a complete system in 2008 that I purchased. I got the Kimbers from same person when he gifted me a pair of Rogers speakers and the Kimber was in a Bi-Wire configuration.
Honestly, hearing much of a difference is really really hard but I feel the SRs have a slightly larger and airy presentation while the Kimber is more just solid and clinical. I am still playing with different music but will probably stick with the SRs when all is done. But there is not a thing wrong with the Kimbers if that was all I had to use.
