At what point can you hear a Fast or Slow Table?

People with very acute hearing and sense of pitch might be able to detect a variance of more than a few percent either way, assuming the deviation is constant, but the majority of listeners will probably not hear this small a difference. However, a substantial number of listeners will be able to detect fluctuations such wow and/or flutter. I'm reminded of Miles Davis great album, "Kind of Blue", which was recorded in 1959 with a tape machine that ran just a hair slow (thereby altering the pitch ever so slightly). This wasn't detected until the recording was remastered in the mid-1990's, after tens of thousands of people had listened to the recording for some 35 years.

So, the speed variation in your turntable probably isn't anything to worry about.

Monk: Gosh, after more than 40 years of listening seriously to jazz, collecting more than 5000 recordings, and teaching a college course in jazz appreciation, I thought I WAS a REAL JAZZ LISTENER. Don't know how I could have been so ignorant about the off-pitch on "Kind of Blue", but I apparently had company -- none of the other REAL JAZZ LISTENERS that I knew were aware of the recording anomaly until around 1990. But I guess we're NOT REAL JAZZ LISTENERS up here in the Pacific Northwest...
