Drew, thank-you. That certainly sheds more light on your situation, and what you've done to solve it.
In reference to the Audioholics article, I think you pretty much answered your own question regarding the centre. Order a second 150 and try it. That way, you can see if you like the 2 together, AND you can compare it to your existing one to find out if there really is something wrong with it. Kill two birds, so to speak. If it doesn't work out, you've got 30 days for return.
Oh, and before buying a stand, cobble something together with a milk crate or such, and see how it sounds first.
