Next upgrade on Usher & Primaluna rig??


I'm contemplating my next upgrades. Would love your thoughts and ideas. Here is my setup:

Lossless Files (using apple lossless but have Flac, Wav & Aiff duplicates)
Apple TV > unknown decent quality optical cable to...
Rega Dac > low end Monster RCA cable to
Primaluna Dialogue One > bi wire, 4 ohm connected to low frequency, 8ohm connected to high frequency. Low end speaker cables, unmatching >
Usher Be-718 speakers
VTI Metal stands

This is my approximate score of each sound characteristic that comes to mind (less emphasis on actual score, but rather how each relates to each other):

Sweet midrange - 90%
Soundstage - 65%
Detail - 75%
Controlled, tight bass - 60%
Realism - 80%
Dynamics - 80%

Here are the upgrades I have in mind:

-Mac Mini (replace ATV. I often have cuts in my wifi connection making it quite irritating, plus the added benefit of sound improvements)
-Usher rws-708 speaker stands (tighten bass)
-Acoustic treatment (I'd rather wait on this due to possibility of moving)
-Upgrade speaker cables (2 matching pairs)
-upgrade interconnects

I suspect at this point for significant change you either need higher efficiency more tube amp friendly speakers or throw more power and current at the Ushers. Rogue Sphynx hybrid integrated might be worth a try for that.
I have heard Prima Luna and Usher gear sound excellent in more than one rig, so you may want to work with them for a while.

Yes, focus on cabling; power cords, digital link, interconnects and speaker cables - all can be very rewarding if you take your time and try several brands. The influence of a set of cords upon a rig is equal to a component change, and will absolutely have an affect upon the parameters you wish to change in your system.

I wouldn't dream of setting up a rig without keen attention paid to the cabling. :)
