What do you mean you “heard” the turntable

If I would dare to say this I would say ''they are pretending'' to

hear whatever differences . But I don't dare.

The TT's are not supposed to ''sound'' so if one hears sound

differences those should be ascribed to the records. Those

may detect what is wrong with the turntable.

The TT should provide optimal conditions for the records.

If this is not the case this can be only heard via records.

One can't test TT as an separate component without

records.

Those digital admirer should either consult an ear specialist or

write for digital forum.

According to Popper there is no theory independent observation.

So ''I have seen with my own eye'' or ''I have heard with my own

ears'' is no argument at all. What we hear or see our brain need

to interpret in the context of some premisses.

Take ''our'' scientist Lew as example.  He own 5 TT's but neither

of them is belt driven. Does he have some prejudice against belt

driven TT? The most of his TT's are DD kind. So presumably he

has some premises about drive systems in the sense of , say,

quality. Can he hear any difference between his TT's by listening

to them ''naked'' next to each other? Well this may be the case

with his Lenco because  its driving system may produce some

''rumble'' which is difficult to supress. That is why he made 100kg.

plinth for the precious (grin). But hearing whatever from his DD

 TT's is not probable. This would imply that something is wrong

with the one with, say, sound on its own.

So this thread is at least not clear formulated. One can only

''hear'' an TT in combo with an record , tonearm and cart. The

last mentioned 3 are those which (re)produce sound.
