Why will no other turntable beat the EMT 927?

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.

Paul,

I agree with lewm, there is no reason to discard the arm.  Rewire if necessary but if the bearings are good I would use it.  I used the 3012 because I had it.  It worked fine, just not the best choice.  The 997 would be better, because it is better.

My modest vintage hifi is in a nice cabinet in my living room.  The broadcast 927 was just too big and industrial looking.  I had considered trying a smaller EMT, but I don’t think anything would be like the 927.  

The biggest thing  with my 927 was taking the motor apart and cleaning and lubing.  The motor was a little noisy when I first got the turntable. After it was restored it was very quite.  
I didn’t even need to repaint mine.  The enamel paint was so thick it would take a hammer swing to mar it.  It was soiled, as was the entire turntable.  The platter bearing is huge, and was perfect.  My bearing was oil based, but I have heard that some are also grease fitted.  (Like Garrard).  

I also had the glass platter.  Some are fitted with persplex.  
The only other turntable that has impressed me so much was the Rockport Sirius III, which a client of mine owns.  I wish I could  have heard them side by side.

I also had the broadcast frame.  My frame was spring loaded, so you could jump and the turntable wouldn’t move.  The frame is designed to sit into a console  which if you have the room I would recommend.

The TSD cartridge makes sense.  EMT and Ortofon has many high mass choices.  I also used my Decca Red which worked well.  
If you have space, this is a no compromise turntable.  

I wasn't planning on selling mine.  A fellow agon member asked to hear it.  Afterward, what he offered me on the spot was about three and a half times what I had into it.  So, reluctantly I sold it.

As I said, I miss it everyday.  Eckart has some incredible turntables, but if his system were mine, I would sell them all and keep the EMT.
