Wall mounting on studs


Hi everyone,

I'm mounting my turntable on the wall, and the shelf system is designed to span over 3 studs (and uses all 3). Since my studs in the wall are currently not where I want them to be, I'm just going to open up the wall and install new studs so my shelf can be installed exactly where I want it to be. My question is, should I just add new studs running vertically from floor to ceiling, or can I add 2x4s horinzontally between the existing studs that are 16" apart? I'm not concerned about cost or difficulty - I just want to know from a performance point of view, what's best to minimize vibration to the shelf?

Thanks!

It would be a lot less work to just attach some thick pieces of wood to where the studs actually are located and then attach the shelf to the piece(s) of wood. 
You should be blocking not adding studs. By code (building date will vary by state and/or municipality--your unrenovated 1860 Manhattan Brownstone will not suddenly have to be brought up to code), studs should be 16" apart inside to inside. Add a solid board to the studs vertically. This will provide you the solidity and stability you need. And anchor well. If you are in an earthquake-prone location, consult with a professional carpenter or a local AV interior or friend in the Pro AV integration market. This is no different than properly mounding a TV display to a wall.

That's what I did while still using the studs on one side. Look at my systems page 
I know an audiophile in St. Louis who went all out and sank shafts all the way to the bedrock below his house for his turntable. I am amazed by his dedication.
Feedback from ones speakers into the turntable is a problem. I usually played the LP only once, and that at low volume and recorded the output to a Revox 77 reel-to-reel tape recorder. That way the LP lasts for a very long time, and no feedback. On the really valuable direct to disk LPs I did not play them at all. When I die I hope someone does not throw them away.
