I always say find a good dealer that has a good return policy. Ask them if they have a floor sample or demo model. Buy it, take it home, try it out. If it don't work, take it back and get something else. What sounds good at the store, might not sound good at home. And what I like, you might not like.
I am looking at getting a B&W ASW608 and my dealer said if it isn't right, just bring it back and I can get something else.
