So how do you know how good a turntable really is regardless of cost?
First, heavy is good! Next, turn the turntable on and have the platter spin. Then lift the stylus up from the record surface using the lifter and then slowly turn your amplifier up. The better the turntable the less noise you will hear.
Any noise that you do hear is coming from the turntable or possibly the preamp or amplifier.
To eliminate the amplifier and preamp, disconnect the turntable from the rest of the system, slowly turn up the amplifier and see what noise is left. Any noise that disappeared is due to the turntable. Of course nothing is quite that simple but it is a reasonable test.
