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 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.
An update:

Just installed outlet and wondering if there's break-in time required. I was very surprised to find that whoever installed the original outlet hadn't connected the ground. Anyone have an idea why an outlet would be installed without the ground connected? I obviously wired it with the ground.

Hydra 6 w/Taipan alpha Helix 20A has been running for five days. Prelim impressions of all this shunyata gear (in-wall duplex, 20A taipan alpha, Hydra 6) is that it's very good. Hearing subtle details I had been missing, and more space around instruments and voices. Sound stage has grown taller and wider, and voices sound less restricted (before sounded like they had a cold). I'm very happy now. So, thanks to everyone who responded. I'm sure I could get good results with any number of the pieces suggested here. I went for Shunyata for resale value if I decide to change, and am happy to report it does what it's known for.
The shunyata stuff is quite nice. You will find significant benefits if you change the stock feet on the hydra with symposium acoustics/black ravioli products. The difference is not small.

Good luck.

If you get tired of the hydra ... consider the Sound Applications gear. It sounds much more natural with the hubbell outlet recommended by Jim Weil.

I used the hydra/sz-1 combo prior to the SA RLS/hubbell combo.
I just inserted an Acoustic Revive RTP-2 into my system, and I have to tell you....I am flabbergasted at the results. Best conditioner I have run, by far. Previous units have included Hydra 4, RS Haley, Audience Adept AR6, and the short-term loan of a V-Ray.

This RTP is a keeper. Now I have to find another one for my analog components.
rather than power conditioner, I suggest you try the power regeneration model from PS Audio. You get significant benefits in the sound without compromises. RGPC is good if you have bookshelf and want to emphasize the low mid to bass because that is exactly what it does. Hydra, although better is bit loose in low bass. After a while, you start to think if plugging your units to any of power conditioning unit really justify the cost. PS Audio unit was the only thing that got me to accept that clean, pure power is worth paying $2,000 for.
