What do you mean you “heard” the turntable

It's what you don't hear other than the music that makes a good TT.

I have a difficult time believing you can hear a significant difference between a $500 turntable and turntables costing $10,000 to #20,000.  All turn tables do is turn a vinyl disk at a constant speed.  As long as their is no feedback they should sound the same.  I thought the difference was the quality of the cartridge.  So, let's say you install an $1,800 cartridge on a $500 turntable, I will bet it will sound great.

I also don't know what the attraction is for vinyl.  Vinyl can only reproduce a fraction of the sample rate compared to 16 bit and 24 bit CD's.  Why would you want to starve yourself of the detail.  I heard vinyl sounds warmer.  However, I would rather hear the highs and mid's in a crisper sound.

There is a very noticeable difference between tables based on the build quality. If you think about from a practical, logical standpoint, manufacturers make tables from different material. There is no way an aluminum table will sound the same as a veneered MDF table which won't sound the same as a hardwood table or a delrin table. This goes the same for the platter material and weight.

 Though I have not done the test I would be willing to bet that a $2000 cartridge on a $500 turntable with sound just as good  if not better  Than $10,000 turntable with an $200 cartridge.  But you would never really be able to tell unless they were in the same system
