I've read some brief comments interspersed in different threads but am hoping to get more feedback. I will be using the minis as rears with the M11s as fronts. How essential is it that I place the minis on stands. I've read some say if you do not put on a stand the sound gets compromised. I planned on putting one on a bookshelf and the other on a tall cd rack (wooden with metal slots). And if stands are indeed essential, what do you recommend that is economical. It's crazy how some stands cost more than the speakers themselves! Thanks for any advice.
