The main reason is that they aren't necessary and don't offer any improvement over the 'conditioning' already built into all well made gear. The so-called 'dirty power' issues they supposedly address are highly over-hyped and are filtered out by the power supplies in your gear anyway. And they can restrict the current supply to your amp, resulting in degraded performance.
soooo just to be sure..plug my big amp into the wall and the rest into the conditioner??I was kinda weiry about plugging my main head into the conditioner for the start.
Right on thx!!
