Hi there, well I found it all out:
I was wrong in my first mail: I ment to note the dial on the right side: this is for adjusting the tracking force.. Now I got it all adjusted in the right way.
I have the AT-150mlx cart on it with a tracking force of 1,5 grams, and damping is on 1: It sounds wonderfull, I have to go through my whole recordcollection again!, I hears stuff which was never there before.. the detail and steadiness of the sound is amazing, furthermore the soundstage is very holographic, not like anything I heard/had before.. To give you an idea; my daily TT before the P3 was a (Pioneer) PLC-590 with PA-5000 arm.
I will certainly never regret getting the P3, it looks wonderfull, and the sound improvement is amazing!
Regards,
Willem
