Adams out of the choice of all 3 for me, their accoustic research and high end stuff is the bizz, and I think it translates down to their lower priced stuff.
I`ve never been a huge fan of the mackies, they are good, but I think a lot of people use them because they are just told to, and don`t really know what to listen for. I don`t find them versatile enough, and in my opinion they are a little too tight in some areas.
It`s all down to personal taste though.
Get your speakers on demo loan or go and use some at other peoples places.
All our opinions here are based on personal preference, so really you should ignore us all and try yourself.
