Racks made of wood

If you budget will stretch this far, Core Audio Designs wooden racks are not only beautiful, incredibly well made, they are extremely functional. I use one with my Michell Engineering GyroDec turntable, absolutely rock solid. Furthermore, the owner of Core Audio Designs, Arnold Marr, is a thouorulghy nice guy to deal with. See my previous post on building a TT system after selling my last TT 33 years ago:

As the previous post states,Core audio stands are beautiful, and their isolation of components seems excellent.

 Core Audio racks are excellent. I have Zoethecus wood racks for all of my electronics, they are very similar to Core racks. But for a turntable, isolation is important. Especially on a suspended wood floor. I use a metal VPI turntable stand filled with sand. My turntable sits on a maple slab with spikes on top of the VPI stand. Before I had the VPI I had my turntable on top of the Zoethecus. It was not a good solution which is why I got the VPI. The VPI is rock solid stable and I no longer have to tip toe so the record doesn't skip. If a wall shelf is not an option, a sand filled metal stand is the way to go.

My turntable is on a Sound Anchors turntable stand which I highly recommend, but it is steel.  I also have a Box Furniture rack that I use for my preamps and it sounds and looks very nice.  I am sure a turntable would sound just fine on it too but I haven't actually tried that.
