@PeterA , @
christensenleif@msn.com , Hi Peter, Lief, I also prefer inelastic belt / string, and using a Mylar belt on my Rockport Sirius II.
However, I have always had this question on the back on my mind regarding the Micro Seiki or similar strings. Since you have to tie a knot with these strings, there must be some sort of a bump when the knot goes through the pulley. I am pretty sure it is inaudible, but did you guys ever check it with instruments, or programs like the AnalogMagik , to see if it showed up in the measurements?
Another question for both of you is about the arrangement of the motor pot. As mentioned by
@Salectric , many Platine Verdier users like to place the motor on a separate rack, yet Thom of Galibier was totally against it when I communicated with him many years ago, stating that if the motor pot is on a separate rack, then the floor vibration may cause the two racks to move slightly differently, causing a microscopic change in distance between the TT and motor, a change in belt tension, then a change in TT speed. That sounded quite logical to me!
Peter, in your case, while the TT and motor pot are on separate steel slabs, they all sit on the same rack top. So, in my eyes, they are still in some ways hard coupled together.
So my question to both Peter and Lief is whether you guys have tried putting the TT and motor on totally separate racks, and if so, do you hear any detrimental effect with this arrangement?
Thanks
