Help w/Power Conditioning: Shunyata, Furman, RGPC?


I'm feeling totally lost with what direction to go with power conditioning in my system and am looking for some help. My system, briefly (click here for full info):

Dali MS4 Utopia Speakers
Pass INT-150 Integrated
Bel Canto DAC 3
Mac Mini
Shunyata Taipain Alpha and Cardas Golden Reference PCs
Purist speaker/ICs
Ridge USB cable

So far looking at the following units and trying to see what people think and what direction is a good way to go (looking at $1400 and under):

Shunyata 6 or 8 (specifically looking at diffs btwn these two, as wife likes 6)
Richard Gray Power Company pole pig + 600 (not much info on pole pig)
Furman Elite 15PF
Audio Magic Stealth Mini Reference
Any others??

Thanks!

thanks tvad, I'll def look into the Maher unit. Still hard to find anyone using the Richard Gray gear.

Lokie: any reason not to have the sac and computer on the same unit? I've heard about having the amp separate from the front end, but why have the sac and amp in same line? I'm going to find out how much it costs to have 20a lines run, but suspect in my building it will be costly, and I'm thinking of moving in 2 years.

So far no one has chimed in for shunyata--interesting
"any reason not to have the sac and computer on the same unit? I've heard about having the amp separate from the front end, but why have the sac and amp in same line?"

That's what I found best for mine. It's an easy experiment.
Thanks everyone for your help. I've decided to do the following:

Install a Shunyata duplex outlet, run the amp directly into wall and get a Shunyata Hydra 6 for the rest of my gear. I can always play around later if I'm not happy with the results, but I think this is an easy way to start, since Shunyata is fairly easy to resell. The Maher stuff is interesting, but will have to try another day. The BPT is also intriguing, but too large for my rack. I think if I was going to try regeneration, though, it would definitely be Exact Power.
