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.
