Table speed


I heard an interesting fact from a musician friend. He calculated that if a turntable ran 1% fast, it would be like hearing a guitar note 1/6 sharp, quite easy to hear. I play guitar and use quarter bends all the time. Just a little less. This makes me all the more concerned about speed. Now in all fairness, if I wasn't comparing it to something or let's say, playing along with a perfectly tuned guitar, I may not be able to tell. My ear isn't good enough to simply say, that is fast, but knowing this does cause some concern in my search for a turntable. Being of German heritage, I naturally gravitate toward order and perfection. (joke) Just thought I would pass this on, and once again, I am not looking for an argument, but If anyone sees it differntly from my friends assesment, please let me know. Thank you and thanks for a great forum. There is a wealth of information here that I will use and try to contribute to in my own humble way.

I have a rega planar 3, and I recently installed the motor upgrade (mostly because the old motor was 220v/50Hz and it couldn't be used in US).
Now I A/B the rega against my CD player and I cannot hear any speed or pitch difference. I can't remember a/Bing the speed with the old motor.
Perhaps rega solved the problem with the new motor?

In any case I think speed fluctuations will be much more noticeable and detrimental than a constant, relatively small, offset.
Thank you all for your input. Twl, thank you in particular for enlightening me on guitars. As a hack musician, I probably should have known this, but thanks for the riminder on all of the issues associated with guitar tuning. When all is said and done, I am sure that my untrained ear probably couldn't hear the difference anyway, but I thought this was an interesting way of cross referencing table speed. (the one percent equalling a 6th of a note) Anyway, on with the search and good listening to all.

Nothing is perfect in life....

Even the ultra accurate ATOMIC CLOCK have precision error......and is not 100% accurate ! With this in mind, I think that all the turning speed of the disc in any CD players in the world are not 100% accurate.
FYI here is some history on atomic clock standards at NIST formally NBS.
