I am putting together my first HT setup while the room is being built. Will I need any special electric. I bought a Monster Power 2500 and it looks like all I need is a Regular wall socket and everything will plug into the MP2500. I will have 2 amps, one for my SVS and one 5 channel for the Martin Logans. The salesman I bought them from never mentioned a regulator but the guy that dropped them off said I should get one and he also suggested I return the MP2500 for a better one. If I upgrade the MP2500 would the regulator be unnecessary. Is the delivery guy trying to make a sale or is the regulator needed. I have done a search here and It doesn't look like to many people use them.
