EMT 927 vs. Micro Seiki 5000 or 8000 - different?

Dear Dover and Raul, Dover wrote, " My turntable speed never changes so I only check it once a year or so " I am happy to hear that, but the statement is not relevant to the issue of "belt creep" and does not necessarily mean that there is no variation in platter speed at the micro level. However, if you love the sound of your tt, that's all that counts. Pay close attention to piano reproduction. The capacity of a bd turntable to accurately convey the sound of a decaying note struck on a piano is for me a measure of its goodness. Pitch should be unwavering until the note dies below the audible level.

Lewm -

Please define belt creep. I have no slip and no stretch in the belt. I listen to heaps of classical and piano and in my previous posts I have mentioned that piano music often often lays bare wow and speed instability in turntables which is precisely why I dont do suspended decks, rubber or other stretchy belts and direct drive. But what do you actually mean by belt creep.

My belt & thread driven units (from two sides each) are controlled very precisely by VPI SDS steering control in conjunction with fly wheels. The R 80 motor is controlled by Dusch Multiconverter thus replacing the felt brake. You see I regard drives & speed control as very important for good analog sound.

My 'common sense'(aka 'not scientific') hyphothesis is:
how can a mouse (stylus) hinder an elephant (platter) in
his movement?

Regards,

Dear Nandric, the stylus drag is a (if small in "value") constant "brake". This loss of speed has to be taken into account. Devices like the Sutherland stroboscope do verify the existence of stylus drag. Simple cure: adjust speed WITH the stylus on the record (i.e. while stylus drag occurs).
