Very limited. I swapped out two of the 4 with different OP amps as recommended by an expert friend of mind and the bass is punchier and a little deeper and the highs are better. It's not that the sound card at stock needs an upgrade, but I guess it's more of a preference. I kinda liked the change, so I stayed with them.
The OP-amps that were recommended to me are mad by National (apparently a very good brand), and the model number is LME49720. I found mine at Digi-Key:
The photo you'll see is just a stock photo that they use for OP-amps when they don't have the actual photo available. However, they do look like that with the exception of having some printing:
You can middle-click his photos and the left-click the photo after it's finished loading in your browser window to get up close and personal. lol
The ones he replaced are the opposite of the ones that I replaced, per the recommendation from my expert friend. The stock OP amps that he replaced here are LME49710s. I replaced the JRC 2114Ds.
I don't know if I could say that it's a HUGE difference, but I like the difference. :) I guess the low end is a little punchier and maybe a little deeper and maybe the highs are better or something.
These are easy to replace. I slid a nail file from a fingernail clipper underneath and pried them upward. They have to be handled gently though because those pins bend easily. They're stiff, but they can bend easily. So, prying them straight up is critical. Inserting them as perfectly as you can is also critical. It's fun though.
