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

Dear friends, To my 15 years involving experience with my (24kgr platter) Symphonic Line RG6, I can add that never I've had to re-align the speed also, but what happens to the MOMENT CHANGES in speed due to stylus friction, is another thing of a great concern. This Shutherland laser equiped clamp can not evaluate this, but you can hear it happens during playing, as like the LP is warped or the spindle hole is off centered. Auditioning the same LP with my DP80 then, and TD124 II now, I can not detect this momentary speed instability. I've lost my faith & I'm trying to get rid this TT as I could'nt find a solution for 15 years of changing strings, bearing oils, PSU inner parts, platter mats, bases e.t.c
Now, please don't get me wrong. I don't want to provoke against the BD approach, but it seems that the point of real concern is not the speed change over a period of a year.
Thank you.

Dear Geoch: Agree, speed stability in the " short time " is the main problem/target/issue for TTs and what we choose on it.

DD makes " things " really well on that subject. You DP-80 is a good example, I can't talk on the Thorens one because I never heard it in my system but I take your opinion as " mine ".

Regards and enjoy the music,
Raul.

Dear Geoch: I'm with you, the very " short time " speed stability is more important that that long year.

IMHO this characteristic in a TT is " elusive " in some BD designs and less in a DD one like your DP-80.

Dear Raul,
My mistake to expose such a dangerous post here.
I think Dover explains this precisely at his 05-04-11 reply.
Please lets pretend that the case has closed by that post, as there is not much to be said further about and we should stop walking in this mine field. Too many of us have invested great deal of money having great expectations and no more than perhaps a handfull of us can realise and accept the fact.
I apologise and I wish to stop this discussion here.
I'm sorry.

My Kuzma Stabi Ref. has 2 motors driving the sub-platter with an single belt. I check the speed with the Clearaudio
Stroboscopic record with the stylus on the record. I am not
able to see any speed variation. The platter is 8 kgr.
I have difficulty to grasp how, say, 2 gr. stylus pressure
can influence the inertia of the platter. The belt creep I
can emagine by the start of the TT but not as caused by the
stylus pressure when the platter is 'on speed'. Some data
about forces involved?
