Those digital admirer should either consult an ear specialist or
write for digital forum.
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.
