I'm trying to figure out ways to improve the dynamics (transients) of my system for two channel listening. I'm running B&W 704 S2 mains off a Parasound A31 through a Yamaha CX-A5200. It seems my system lacks midrange punch like the snap of a snare etc. I kinda feel like it may be a room issue, but I'm trying to figure that out for sure. Any suggestions?
