Any decent guitar player who has used their computer as an effects unit could tell you this. I can easily perceive the difference between 1.3 and 2.6, and 2.6 and 5ms latencies. And there's at least one person (also a guitarist, who I have added to the cc:) who swears he cam perceive the difference between 0.6 and 1.3ms. Soundcard ADCs typically add 1.5ms latency in each direction, so the actual floor seems to be around 3-5ms.
