I don't post much anymore because of exactly what is taking place above is just tiresome but here is my 2 cents for the OP.
I have owned numerous TW Acustic tables, all one has to do is look at my previous posts and read.
-Raven One
-AC3
and lastly TW's reference FLAGSHIP table the Black Knight.
It's going to come down to a personal judement call but in my own set-up side by side "BK vs MS 5000" I GREATLY prefer the MS 5000 with mod by far. My MS actually has the upgraded Stainless Steel platter which comes with the 8000, I might be the only person with such and there is no ringing.
I also have the same floating platter mod as Sytax
I can go into detail but why, so many individules take such personally so no need to upset anyone, just enjoy listening to your music with what ever it may be.
I feel very fortuante to have learned what I have and to been able to do a side by side comparison without any presure.
I'll give you just one small but VERY IMPORTANT difference the MS has over any TW tables I owned and that is it's accuracy for speed, no matter what speed set for or music you are playing non of the TW tables I owned could keep a 100% accurate speed. This has a dramatic effect on rhythm & pace, which has an effect on the music being played over all.
Here is another test to do, with your stylus down on a record playing or not tap anywhere on your TW table, stand, isolation and you will hear the thud threw your speakers, do the same with my MS dead silence, nothing. Air born frequencies are a enemy for any vinyl lover and that's why we hear dramatic differeneces sonically using isolation so just imagine the positive effects as what I have wrote above with no negative effects.
These are only a few areas
