Zero Surge 8R15W

I recently had an Integrated Amp fail and it occurred to me that it was the only component in my 2.1 audio system that didn’t have any surge suppression. I've always kept it plugged directly into the wall outlet since I experienced slight sound degradation (bass & dynamics) when plugged into various line filters/surge suppressors. I looked into numerous protection methods and determined that a good series mode surge suppressor was more than up to the task. After reading numerous reviews, I decided to give the Zero Surge 8R15W a try. Very nice people to deal with and their discount for military personnel and veterans made for an easy decision.

I received the unit and installed it in my system. Am happy to report that there was no degradation in sound quality when the Integrated Amp was plugged into the Zero Surge suppressor versus plugging directly into the wall outlet. I then decided to also plug the subwoofer into the Zero Surge and found no measurable (SPL) difference in sub performance. At that point, I sat down and listened to various recordings and noticed that the sound seemed to be smoother and better integrated. Perhaps having a common ground point and power feed for all the components is responsible for the improvement. Also knowing that everything is well protected is comforting.
