You can also use a ball bearing platform like the one Berry Diament recommends. He is a recording engineer who believes that very low level vibrations have a large effect on sound quality. I have used them and they do work. He has an interesting web site.
TT to another room, no vibs, better sounds?
Hi All,
A few years ago I thought I'd build a Turntable that is still about a year from being finished. The thought was mass is where it's at. If it's heavy it will take more energy to get it excited and vibrate.
After I picked up a few thousands dollars in parts my machinist asked me what I was trying to accomplish. My response was," The heavier it was the less it would vibrate."
He said, " Take it out of the vibrational environment and save money." I can do that soon and wonder if anyone else had the same thought and realized a cost effective improvement instead of spending more money on a better TT.
