Regarding your wish for a "magic bullet"...no pics of your room and not sure why it sucks BUT do look into room treatment. I went with GIK Acoustics. I think people consider this a subtle, esoteric , expensive tweak with low bang for the buck performance. In my experience it is not. Call GIK. Send them a sketch. At the very least, consider putting a pair of their bass traps or even just (242s?) behind your speakers. I think you will be amazed. Resolution without harshness; better soundstage depth; an overall better listening experience. Good luck.
