Grand Prix Audio Monaco Turntable


FYI, Hi Fi Plus (an excellent UK audio magazine) just did a very thorough review of the Monaco turntable. I have had the turntable for a year and think it is incredibly transparent and very involving - you really get pulled into the music. I could never explain why I found the turntable so engaging, but I think Roy Gregory has done a very good job of explaining why. I have had the VPI HRX and am very familiar with a number of the high end tables (e.g., the SME 30 and top of the line Brinkman)and thought those tables were very good, but I never had the same connection with the music as I do with the Monaco

So much talk about speed stability. Hi-Fi+ says the speed accuracy of the Monaco is better than .002%.

I'm posting something I posted in another thread. Below is my account on how you can achieve as much as .000083% accuracy with your own turntable.

Conversely, what if you manage to time the speed of the platter perfectly. I would think one should take into account the vinyl micro-slipping on the platter.

I have the same album for vinyl and cd. The cd plays on my headphones. The vinyl plays on the speakers.

I play the vinyl a split second earlier than the cd then I slow down the platter down by dragging my fingers on the platter. I do this until both are synced. You know this when you have the headphones on and the speakers seems to disappear completly in the background. It's a zen-like experience in itself.

So both are synced right now. If the drums are still locked synced after one minute. You are more accurate than the KAB speed strobe.

The KAB has a .03% error rate. A .03% error rate between the CD and the vinyl has a slight "reverb" sound. It's very obvious.

My profession is in the visual effects industry for tv/film. I did a test on Adobe After Effects on how a .03% error would sound. I did this by slipping an audio track one frame ahead of it's duplicate. Video is 30 frames per second. 1 frame error is .03%. Now I know how 'bad' a .03% error sounds like and use that as a baseline.
----------------

On my vinyl speed test. My vinyl was able to hold up to 6 mins. before it sounds like it has a .03% error, (or .03 seconds time shift between the cd and the vinyl)
6 mins = 360 secs.
.03 / 360 = .00008333

conclusion:
It takes several times to make the vinyl lock in with the cd before you can start timing how long it is synced. But after such, you can brag your turntable is accurate to ten thousandth of a second. :)

Would like to see how long you guys can keep both sources synced. Would make a great contest.
Sure, if speed stability is in question then you should be able to hear one source run a bit behind,then eventually catch up again to achieve the .00008333% error after 6 mins. That should be something noticeable during the test but it didn't happen on mine. :)

I didn't get to add, ideally I'd like to have the turntable on the left side of the headphones and the cd player on the right side of the headphones but I don't have the right cables for such.
