AC Conditioners?

I too have had good results with Chang Lightspeed. They have different models depending upon your system/needs ranging from quite affordable (the 3200) to somewhat more expensive (6400 or 9600 or 9900) but none considered high-priced. Changs are also nice because they don't constrict dynamics. The internal M.O.V. (metal oxide varistor) transient protection devices are good ones that don't degrade. Cheaper (low power rated) MOV's can deteriorate if they're hit enough times with large enough transients; however this is not usually an issue unless you take a direct lightening hit. Mike VansEvers has some nice stuff & it's tunable for your rig too. Have never tried them, but have read a lot of good things & Mike is a good guy to deal with (he worked with me on some other power issues). His recommendations regarding affordable way to fabricate a dedicated power line worked wonders for me!

Re: twisted (or braided) conductors - this relates to something about the magnetic flux fields cancelling each other. You'll find that some upgrade AC cords are made this way too. If you run a dedicated line this way (I did) you must run this twisted wire bundle in a conduit (or in 3/8" Greenfield if code permits - much easier to work with).
