Ah, if your system is very bright, then the SHB might not be for you. Is your system so bright that you get fatigued quickly when listening? If so, then i'm not sure an interconnect will solve the problem for you, it'd be more of a component upgrade needed.
However, if your system, by nature, is just on the bright side of neutral (like my system-Lean on the bass, but not uncomfortable treble) then I would say to give the SHB a shot.
