Which speakers did you find bright, fatiguing or just disappointing in some way?

the kef ls50s disappointed because they were not transparent enough, they sounded like midbass and treble but still very good.  

my psb towers were neutral, unrefined and forward to a fatiguing fault but at the same time had too much bass.  

the spendor D7 were overall awesome but ultimately too much midrange even though it was clean sounding and not enough midbass.
