Well, there are obviously lots of reasons why a system might lack focus including, but are not limited to, lack of vibration isolation, lack of sufficient or correctly placed room treatments, disregard for cable and fuse directionality, disregard for absolute polarity of the system, there is at least one problem in the system, disregard for the magnetic field produced by large transformers, insufficient damping of circuit boards and CD transport mechanism and non optimum speaker locations.
