Why will no other turntable beat the EMT 927?


Having owned many good turntables in my audiophile life I am still wondering why not one of the modern designs of the last 20 years is able to beat the sound qualities of an EMT 927.
New designs may offer some advantages like multiple armboards, more than one motor or additional vibration measurements etc. but regarding the sound quality the EMT is unbeatable!
What is the real reason behind this as the machine is nearly 60 years old, including the pre-versions like the R-80?

My 927 came with a Ortofon RF 297 arm.  I was told by the people at Dusch in Germany it was made for mono use and I would be better off with a RMA 297 or the EMT 997 arms to use with the TSD cartridges.  I am not sure what I want to put there.  Dusch offered me an exchange for a 997.  
I will most likely send them my 139st to have look at and make sure it is operating at its best.  
I want to mount a second arm on mine like Eckart(thuchan) did with his,  I just need to fabricate something.

Too bad you couldn't keep you EMT.  
Any advice from anyone is always greatly appreciated.

I still think that the question is impossible to answer as stated except
if we believe  that clairvoyant is possible. The question should be put
in present tense:   ''The best TT at present''. 
Pcosta, “Made for mono use” when applied to a tonearm can only mean that it is wired for true mono, with only two signal carrying conductors between headshell and the tonearm output single RCA plug.  That situation is easily rectifiable by any of several persons who are competent to rewire tonearms. I see no reason to discard the tonearm that you have just because it is said to be mono. Even if there are only two contact points between the end of the arm wand and the headshell, even that can be fixed. One can purchase a replacement plug that is capable of stereo, with four contacts built into it.

My EMT RF 297 is already wired for stereo with the 4 pin diamond EMT pattern connector.

So, did you exchange the original Ortofon RF297 arm for an EMT RF297? What don't I understand?  My only point was and is that there is in reality no such thing as a "mono" tonearm, provided one is willing to re-wire.  I would have guessed that re-wiring is less expensive than doing an exchange with a dealer, tonearm for tonearm.  That was my secondary point.
