Promised to tell you something about my latest (small) upgrade for the P5...
Decided to try the white belt to see if it made a difference.
Ordered it from Analogue Seduction (on Ebay). The first belt got lost in the mail, but AS sent me a new one. Thumbs up!
To be honest I didn't expect this tweak to make any difference in the sound from the P5.
But I have to admit that it made a noticeable effect.
The sound is fuller, with more "body" and the focus/precision is better.
The bass is tighter and more "snappy", and the surface noise and backgroud noise is lowered.
Pretty unbelieveable.
But after a while I suspected something was wrong.....
I couldn't free myself from the thought that something was wrong with the speed of the platter. Speed instability was sometimes terribly noticeable.
I used the protractor from this website to check the speed.
The lines stayed put, but then moved ever so slightly every two seconds...
My paranoia made me refit the suplattter and change the oil.
After this operation the speed was 100% stable.
But the problem appeared again!
Today I discovered what seems to be the problems root cause....
It looks like the belt gets a small "ripple" around the motor pulley, and this ripple takes a bit of warming up to be straightened out?
I guess 24-7 playing would eliminate this issue, but that is not so likely to happen....
Maybe it will diminish after some break-in of the belt?
Only time will tell. Until then I keep on enjoying my P5.
Best Regards
Rolf
