That's very interesting. May I ask, what is the point of changing them? Incase they are damaged or a increase in quality? Would the Burr Brown OPA2604 be better, sorry just curious. Would like to know the extent.
So those 1 I posted aren't any better than Resonix? I'm trying to get the best quality product for my system. Any links for comparisons would be appreciated couldn't find any Facebook group.
