I use a pair of Furman 6B-SS power blocks simply for surge protection and convenience. Didn't notice any audio improvement or degradation but i have the comfort of protecting my gear and the added simplicity of disconnecting my whole system from power with the flick of a switch. Great piece of mind when I'm traveling or otherwise away from home. Got em both new for $66. Cheap, effective protection.
