Matt, if you are using your digital set-up 75% of the time in your speaker auditions, IMO you should consider replacing the Mac mini with a dedicated audio server before making your final decision on speakers.
The difference between using a tricked out Mojo Mac mini with outboard linear power supply, and just about everything else that can be done to a mini, and changing to an Antipodes DX server was so significant in my system that I suspect the mini may be limiting the true abilities of the speakers you are trying, particular at the level of resolution your system displays.
To try and explain the differences, I would say the DX sounds more natural, and certainly more enjoyable, because of the absence of a bit of edginess displayed by the mini, in comparison, and because of improved body, tonal density and depth displayed through the DX. It is not particularly night and day but the last 5-10% rarely is.
