What do you mean you “heard” the turntable

bingo.You hear a system. With time and excprience you may be able to differentiate the individual contributions.I strain to understand each component when i match levels and use known components.  And i design this sh!t.  Its hard!  people who claim to hear differences with out a known basis oar deluding themselves.

I share the same dismay when someone says they “heard” a given component at an audio show (or at most dealers, for that matter). 10 different people can “hear” 11 different individual components in the same system. 

I have a new Technics SL-1200G and vintage SL-MK1600 MK2.  With all things being equal except the tables, trust me, I can mostly certainly hear the difference.

Do you think the old Technics tonearm + old wiring and new Technics SL-1200G tonearm + new wiring are equal ?

I think the platter on the new Technics is much better damped, the DD motor is coreless compared to the old inferior motor, footers and the whole plinth are completely different etc. 

So which one do you like ? 

I was listening to my VPI Traveler w/Zu DL-103 MkII in my system, pulled that 'table and transferred my Garrard 301/Ortofon AS-309 into it's place using the same Zu cartridge. Everything else in the system was exactly the same. Immediately the idler drive 301 made its presence known. More slam, a much bigger impact, and a more precise speed were absolutely evident to begin with.

If you can't tell the difference between an idler drive 301 and a belt drive Traveler in an identical system perhaps there's something else going on.

I won't even begin to speculate on the reasons for some of the red herring distractions that have been offered up on this thread in opposition.
