Please don't take this the wrong way, but I never understand these threads. It's fine to ask for insight to share experience, but there is no way I'd use the input you get from people to determine which output tap to use.
In my mind, no matter who you are getting advice from, your mileage will vary. Their system (amplifier, loudspeaker cable, and loudspeaker) and tastes are going to differ from yours in some way. You simply MUST experiment on your own. For just about every speaker, its published impedance value is of little importance in relation to its impedance and phase angle curves, and even less importance in relation to how your particular amplifier is able to drive that load, using your speaker cables.
My solution is to try both, and evaluate each over a period of a day or two. Play a variety of music, and see which works better for YOU.
Good luck!!!
