Surge protection for SF Line 3

I highly recommend the Richard Gray system since it is a "parallel" conditioner. Chris Johnson is probably most concerned about current limiting - NOT an issue with the RGPC 600 or 1200 (or even 400). Being a parallel conditioner, it is the most effective at eliminating line noise without imparting it's own signature.
My experience with the Hydra is that it was a little too smoothing for my system but may work for you. But, again, it will be inline with the power and probably what Chris Johnson is suggesting you avoid

My budget is about $600.00 for this unit

Hi Spaz,

I can vouch for a Furman Elite 15PF which I use for my equipment. It will not limit the current to your power amp and I never found it to have a sonic character of it's own.
It's cost is about $600.00. Just have a review at www.audioadvisors.com or Furman's own website. I replaced my PS audio set up with the Furman. Reputable company and has been in the business a long time.

With regard to the Zero Surge, Brick Wall, SurgeX, and Torus, since they all use the same technology, does any of these units stand out above the others? Or are they all the same? Do any provide power conditioning as well as surge protection?
