Hi all

I am redecorating my house and I am looking for a new way to place my turntable.

I saw the following... Well, "block" I guess. See attachment. It's concrete and is very sturdy, and very heavy. It's not 100% concrete since it would then be unmovable, but still heavy enough.

Is it a good place to place my rega rp3? I wonder if the material itself would have an impact. Wouldnt wood be a Better solution?

Its not unusual to put a turntable on a slab of concrete. For extra vibration isolation place it on a bicycle tube sandwiched between a piece of plywood and the floor. This is a trick that was first devised by people who were working with lasers that demand an ultra-stable platform.

You can go to Home Depot and pick up some over sized slabs of smooth tile works well too.smile.gif

If you want something heavy, solid, and pretty - no, beautiful.... go to a countertop shop that makes their own out of quartz/granite/marble. They typically have "remnants" or leftover pieces from larger jobs. Since you only need something like a square foot or two, you might get something really stunning for $100 or so. They will cut it to size and polish the edges.

We just had our bathroom vanity top done in remnant quartz for less than what corian normally costs. I asked him about making a couple of pieces for amp stands and got two beautiful granite pieces. I'm either going to make stands that will straddle my two 12" subs or I'm going to put them on top of the subs with layers of cork and neoprene between the granite and subs for vibration absorption. I'd like to find a way to measure the vibration though. These are tube amps, so I think vibration control would be more critical than it would with SS.

A large mass is not the best solution for a turntable base.

You want something fairly solid, but not so massive.

The main thing is the isolation provided by the suspension of the turntable itself, plus possibly setting it on an isolation base unit.

A big mass sitting on some kind of spring is how commercial isolation base units are made. The laws of physics suggest that this can work really well. Why wouldn't that work for a turntable?

Here's a relevant google search:

This is cool!

I haven't tried them yet. Both are free. I don't know how accurate, but probably accurate enough for this purpose. I think I'll measure vibration on the top of my sub with a test tone, then on top of the granite which is on top of neoprene which is on top of cork which is on top of the sub! I dunno why she swallowed that fly, Perhaps she'll die. (sorry rolleyes.gif) And compare the difference.

Could be used for turntable also, obviously.

Just thought I'll post an update - I eventuall decided to get the Rega Turntable Wall Mount. In White smile.gif.

It's made specifically for Rega turntables and has a foot holder for each of the 3 feet. Light yet sturdy, as intended.

Still didn't mount it so no idea if it makes any improvements.

What happens when your wall starts to vibrate?
