For a complete novice who happened to have Denon 550 home theatre and a pair of Acoustic Energy Aegis EVO Three floorstanders, what is the most efficient way to make this setup sound better then playing back music CDs? Do I need a 2-way amplifier? A separate CD player? I already have a 6-way amplifier, DVD/CD player, 5 small speakers and a subwoofer i.e. one-box Denon 550. But I am disappointed with the sound even if I use my floorstanders and sw in a standard stereo mode (i.e. w/out the small Denon speakers). I thought I might need a separate 2-way amplifier but have no idea which one? Will I then have to disconnect the floorstanders and the subwofer from the 2-way ampf and connect them to the 6-way one each time I switch from listening to music CDs to watching movies? Would appreciate your comments and sorry if these are silly questions.
