What I've experienced experimenting with footers is that they typically make the system sound different but not better. At first, the novelty of a change leads me to conclude there's been a net improvement but with time I realize I've merely exchanged one shortcoming for another. I eventually happened upon a line of products that, to my ears, improved resolution and imparted an overall sense of ease and this brought my experimenting to an end. I could envision trying a higher level within this company's products to see whether the benefits were worth the added cost, but I don"t feel compelled or driven to do so.
