Amazon.com: Furman Power Conditioner (SS6B): Electronics

Before I changed to the Furman I had hum issues, which I had been attributing to my Yamaha HS5 powered studio monitors that I’m using as a stop gap until I get higher end speakers and an amp, but I’m not sure I need to do that so soon now. Immediately after swapping everything to this Furman surge protectors I noticed instant improvements.
