Dirk Lötsch of Hannover, Germany has tweaked his Planar 3 and he commented:
"Now, all the items (Motor base, dual pulley, silicone belts, aluminum feet and thrust bearing) are installed (takes about 1h) and it sounds fantastic (great mids and straighter bass)!"
"1) No more wow from the bend in the white belt.
2) Speed seems very stable. I have not been able to hear any "macro" pitch issues, meaning, to me, no audible pitch fluctuation. Basically no wow. I am no longer frustrated with records! I was getting to be quite good at hearing very subtle pitch fluctuations.
3) The turntable is more quiet and clear. It seems easier to hear and enjoy the music at both low and high volume levels. At higher levels, it's easier on the ears and at lower levels its easier to hear.
4) All the important musical stuff better: instrument timbre, attack, detail.
5) Sounds like I went up to a better class of turntable.
Overall, I'm very happy with the improvement and I think it was a good value for what I got. "
