As Eric mentioned the Furman units are surge protectors first and top notch. I think the idea of “conditioning power” is dubious. However, keeping voltage as constant as possible along with surge protection is a smart thing. I need surge protection like Eric, in CO, t-storms can be monsters. Very real deal. This year I’m installing a whole house surge protector and dedicated line. For now I too use a Shunyata Hydra 6 for my amps and front end along with the Furman PTS-6 for digital, TV etc. they haven’t failed me yet. The new Viper block looks like a winner IMO. I like Shunyata gear, it has served me well overall on the power side of things. I’m considering an upgrade of my block to a unit that can do all my system as one… not sure what that will be just yet.
I think the most important question you need to ask yourself is how robust of a surge protection unit you need. If your needs are minimal then I think about any decent block would get you where you want to be.
