I've had some bad rooms too , but I never let it detract from my enjoyment of music . 

  I'm with Art on the subect of traps etc . They can help fine tune your room but most are just to god awful looking . There fine in a studio but not in ones home . 

  I mostly use natural room tunes with excellent results .

Unless you are fortunate enough to have a listening room with naturally good acoustics, some sort of bass trapping and absorption of early reflections will probably be required if you want to optimize the sound. Personally, I would love to see the waterfall plots for the in-room measurements that JA has performed. It would be very interesting to see the time-domain behavior of the reviewer's rooms.
