I have always just bought entry level Denon receivers. I know they lack the power to drive the better floorstanding speakers. I want to stick with a 2.1 system for home theatre and gaming.... don't listen to music much. My questions are what does a pre amp do? DOes it have all the hookups for dvd, gaming, vcr, built in tuner and HDMI ins and outs just like a receiver? Just without the built in amplifier? I would like to get a nice pair of floorstanding speakers and an amp that does around 300 to 400 watts x 2 rms into an 8 ohm load. Any help you guys can give me would be great!
