So.. I'm going to ask the annoying famous question... which one should I buy and convince me why? Equipment it will be powering.. Paradigms: Titan's v3 mains CC-170 center Atoms v3 surrounds JBL E250 12-inch sub I don't have any particular affinity to any one brand. It will be replacing a Kenwood VR-507 that is having some intermittent remote problems. I also feel like maybe my Kenwood gets kind of strained sounding after the volume knob goes beyond 50% or so.
