I know almost nothing about how sound words. I recently installed new audio gear. To me it sounds bad, as if it's being muffled. I am connecting my PC to a Schiit Modi Multibit DAC, which is connected to a Schiit Magni 3 amp, which is connected to a pair of JBL LSR305/30X studio monitors. I am not sure if I am perceiving the sound to be bad simply because: a) I am hearing its intended "flatness" (I don't know what "flat" sound is supposed to sound like) and I don't like how the "flatness" sounds, or alternatively, b) if it sounds bad to me because some of my gear is not performing properly. Therefore, in this thread I am asking: is there an objective way by which I can determine whether or not my gear is performing properly? Similarly, I need to isolate which component(s) is causing the sound to be this way...but I don't have the luxury of owning other parts to swap out. Ideally, I'd prefer to use a software tool that can identify a problem, if one exists.
