Power Conditioners

Hi ecrotty
Your question is a very sensitive one and if you play your cards right you can be ahead of the game. I happen to have the Furman that you are considering. I also have a Zerosurge ten outlet power surge protector and a Synergistic Research Powercell 12 UEF SE. The best use of your money at this point of time would be to get an electrician run a dedicated line for you with 10 gauge wire  and 20 amp fuse terminated in a good hospital grade outlet. From there you can start testing different power solutions and pick the one that works best for your system.  While you have the electrician, have him install a whole house surge protector for you. Get one on Amazon for less than $200. It takes about 15 minutes to install. The whole job can be done in an hour (dedicated line plus surge).  I hope that helps.

Look up /misc-audio/124713-3466

Before I bought any conditioner I would install a dedicated circuit.
After that if you have power surges or brown outs the next consideration
should be Environmental Potentials EP-2050 system. Cost about $1,000.
After those two moves you should look into power regeneration. Conditioners are the last move.

I had an AudioQuest Niagara 1200 on my system and it didn't do much for my sound.  Moved it to the office system just for the surge protection.  I'm a McIntosh tube guy.  I just last month added a McIntosh MPC1500 Power Controller and it made the most significant improvement I've heard in my system, by leaps and bounds. Of course, it costs as much as your system combined.  But, Holy Smokes, what a magnificent upgrade it was.  Wowza.  I love it.  

The devices linked in the OP are not power conditioners. They are power strips with surge limiting. They will not improve the sound, but they may be helpful at preventing damage from power surges and lightning strikes on the power line.
