Here's the deal,I am thinking of having a pair of Studio 100 driven by a Pioneer Elite VSX-55TXi. I am also thinking of adding an amp to this system but i thought twice about it if I should go with seperates or stay with pre/pros,when i saw the price of the P5 Anthem. I've got few questions to ask about amps,here they are: 1.Let's say we take the P5 Anthem,does it cost that much because of the amount of watts it delivers? 2.If I choose another amp that is less powerful (less watts) than the P5,does it mean that the sound quality will degrade? 3.There's something fundamental about amps that i don't understand,let's say your main receiver is rated 100 watts per channel,and you add an amp to your setup that is rated 150 watts per channel.Does it mean that the total amount for each channel will be 100+150=250 watts ? 4.Does it really make a difference in sound quality to add an amp to drive your speakers? 5.Do you guys know if there's a very powerful 2 channel amp that is not to expensive let's say in the 1000-1300$ price range? Thanks a lot in advance!
