I did the "SKOL" test both while not recording and while recording (let it run for 15 minutes) on a Phenom 384 25, Phenom 640, Super Yoter 50, and a Super Hogster A3 today. These are the thermals I have at my residence currently. To my eye, there was no lag. I had my daughter who is a musician, and she claims to have a lot better sense of time and sound. She studied it for a long time, and she thought "maybe" there is the slightest bit of lag. She said if there was any, it was something like "1/32" of a second. I experienced nothing like what Decoyed reported with it being almost 1 second delayed on the iRay.
Again, I am not doing the video test from YouTube because that is not a test that validates the potential issue of lag.
