It seems this thread has shifted into a discussion about wow & flutter, and I believe I’m responsible for that. I’d like to apologize to everyone. I initially asked
@PeterA to measure his AS2000 turntable and/or AN turntable if possible. My intention was to gain insight into the wow & flutter performance of AS turntables in general and to explore ways to improve it by suggesting small adjustments to the thread and platter. However, as
@PeterA pointed out, the discussion took a different direction. My apologies for that.
By the way, the Android app you’re using is not on the same level as the iOS app. Please consider using the AM software and/or the iOS app and sharing the results under calibration devices.
