I was wondering if anyone has compared the old FLR9G30 and the new XC900M?
I'd be curious to know the same thing. I tried out an FLR9G30 back when it first came out. It was better in some respects and worse in others. I gave up on it and stuck with the XR9's that I knew and trusted. I hear that the XC900M cards are a major improvement, but I'd be interested to hear some real world tests between it and the XR9, and between it and the previous FLR version.
I have one of the XC9 cards on order and UPS says I should have it tomorrow. I'm going to put it on a tower that has been having a lot of noise issues and see how it does. I'll report back when I get a chance to try it out.
