[Formerly YB-2]

Based on another discussion of line filters/surge protectors by Serge & Dan, I purchased a SurgeX XR-315 from Ivan. I installed it this evening and was an immediate improvement in removing what I will call 'grunge' from my system. I had hoped for a noticeable improvement, but nothing like the XR-315 achieved. Was surprising enough that I went back and forth to A/B between it, my many-year old Monster HTS-3600 MkII and the PS Audio Ultimate Outlet. The XR-315 being fed by the Ultimate Outlet was the clear winner to my ears. While it might not be up to the standards of some of the $4K+ AC regenerators, it was a very worthwhile addition. If you looking for an industrial strength surge protector with RFI suppression capabilities in a small package, check out the SurgeX line. A most worthy upgrade at a reasonable cost.
