Hey Joel,?
If you have a socket on the board I would definitely switch it out. Sound quality is really very good, although I never actually heard the rig with the 2822 so it's not really a comparison. If the chip is soldered in I don't know if it would be worth the bother, especially if you have everything working now.
Thinking about doing a pop fix but haven't picked one yet.
