Alright guys. Longtime lurker, new joiner here. I wanted to check into some of the expertise on the site I often read about. My current setup is FR Definitive Mythos STS FL Definitive Mythos STS C Definitive Mythos 9 RR Definitive Gem XL RL Definitive Gem XL Sub Definitive Supercube I AVR Pioneer vsx-21TXH Now my big question is what is the best part of this system to upgrade? I'm thinking an external amp (like mcintosh). But these are powered subs in each front speaker as well as self powered seperated main subwoofer. So really no idea where the best upgrade would be. I like sweet sound, and think I have that, but it could be better. For the record I enjoy movies as well as music on this system about 60/40 in favor of movies. Thanks gents!
