Macrojack had hit it right on the head. This is pretty much the same method I use when I decide whether I like a component or not. The one thing I try to do with the new component is leave it in the system for a couple of weeks and listen every day to get very familiar with the sound of that component. I do not analyze the sound during this period, but try to enjoy the music. Many times the differences are subtle between well designed and built products. Some of these differences will be important to you and others will not, or maybe you won't even notice them. As Macro states above, when you put the Sunfire back into the system after the couple of weeks, you will know if you have to have the new stuff or not.
