Yes. We used the recommended underlay from corka. it was extremely dense, and the people who did our kitchen loved it. It is cork specific and claims "excellent" acoustic performance. It's certainly a lot quieter downstairs than the adjacent wood flooring (of course) cork is quite soft too which I imagine helps a lot. Haven't got an AB test to compare it to, but, happy.
Thanks that looks like what I had in mind. Which cork flooring did you use, I guess corka? I was looking at cortex and wicanders. I emailed them asking their thoughts.
