I'm in the market for some power conditioning rack units, maybe two of them: one for my guitar rig and one for my computer/recording rig. As it is now I have a mess of a power situation here, I'm using a lot of power strips and expansions and it's all going to the same outlet, guitar rig, recording rig, and computer. On top of that I don't think I have very clean line power as it is, so I'd like to address this at this time. I'm a small bit familiar with the concept of power conditioner units as I know there are different tiers of effectiveness. At the lowest end of budget power conditioning the units don't offer really anything different than a power strip from wal-store. Not my area of interest. The very best in power conditioning units generate their own output sine wave so the power supplied is 100% clean. Not my area of budget. Somewhere in the middle is a happy middle ground I think, something that is effective and will solve my power problem, but won't cost me more than $500 per unit. Any suggestions? So far I am looking at these, but I'm open to any suggestions: http://www.sweetwater.com/store/detail/PL8C/ http://www.sweetwater.com/store/detail/PLPROC/ There are also intermediate grades, but those only have the addition of digital readouts of what's going on, but no added functionality. I think.
