Ok you pros what is the real lowdown?

I've been hearing good things about the BBE sonic maximizer. Are any of you using or have any of you tried one? It has been described as taking the pillows off the speakers.

Also I'm looking at the Presonus blue tube mic preamp. Would this be a waste of money going from it into the mic input of the X1. I've been told that a tube mic preamp adds warmth to the vocals. Is this true or baloney?

Regards,

Tom
