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


Using the KAB speed strobe my Turntable is right on speed. However, when accounting for stylus drag the speed drops to precisely (according to KAB) to .37% slow with the needle in the first track. Is this minor enough to just let it go? Can this even be heard by someone with perfect pitch?

The table is a brand new P5 with TTPSU

I would worry about a .37% speed drop due to stylus drag, if it really is the case. This because stylus drag - and more importantly the torque on the platter - depends on the amount of groove modulation and the position of the stylus with respect to the center of the record. It is therefore likely that the speed drop will actually vary - and therefore cause wow - depending on the music being played.

But, what do I really know - I use a quartz oscillator locked direct drive...

My ex-wife is an opera singer with perfect pitch. She would walk into a room with anything playing (TT, CD, and of course live music), and the first thing she would do is start to hum with her hands cupped over one or both ears. I do not think she could help it, the music had to be right on, or it drove her nuts.

I however, am not cursed that way. It once took me a few minutes to realize that the belt had slipped on the TT and I was listening to a 33 at 45 rpm. The violin was "just not right". It might be a "right brain - left brain" thing.

A fast or slow turntable will affect the pitch of the music. The accepted standard today is 440 Hz for middle A, but there has been wide variation throughout history, and even some variation today.

See http://www.uk-piano.org/history/pitch.html.

There was an international squbble once about the pitch of the Vienna Opera. It was too high, said many Divas, and bad for their voices. Musicians know that tuning just a bit high makes the music sound more exciting, and some do it on purpose.
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...
C'mon Monk, aren't you being a bit hypercritical? After all - as all REAL JAZZ LISTENERS know, there is no such thing as as an absolutely correct pitch. You should be able to play KOB in any key whether it's a half step down or two steps up!
