The B&W 800 series are not excessively bright, and certainly not crap. In general, they are a tad bright... which is why they are often paired with MacIntosh equipment which tends to lack detail and is strong in midrange and bass. If they seem excessively bright, then it is a question of electronics and setup. I own five 805 Matrix... they sound great. Equalization should be reserved for very inexpensive systems or extraordinary setup problems. It is symptomatic relief, best fix the problem.
To really help. We will need to know the rest of your components and setup. There is a place to put photos and ID equipment under your user ID; Virtual Systems. With this we could probably bring specific recommendations.
Most likely source of excessive treble. Trebly electronics, speakers pointed directly at you... so toeing out the speakers can help.
