Oooooh, a spooky reanimation of an undead thread!
Hi guys, I just bought a Matrix M-Stage (latest version), but didn't think about upgrading the op-amp.
Based on this thread, people seem to love the 797, but sheerly based on reviews from TamAudio, people also love the 627.
So my question is, what's the difference between the two? Based on the latest m-stage is this upgrade going to make a huge difference? Is there anything I should know about upgrading an op-amp (I've never done it before)?
