Thank you. Bought the necessary the only difference is I used sorbothane feet between the granite boards. My word it totally isolates my turntable and improved the sound brilliantly.

Yes this works a treat, I have used just a single block of granite with rubber feet, when I had to adjust for levelling I just used a few coins, even a single block works brilliantly, but having two would certainly eliminate any chance of a single ounce of resonance reaching the turntable, I think I will buy another to follow your example !

Very nice and cost effective, these things really make a big difference. My isolation platform is a sandwiched construction of hardwood cutting board, rubber doormat cut to size, and glass cutting board sitting on a bicycle inner tube. The doormat has a fibrous surface on one side which allows me to slide it on the glass cutting board for leveling. It may actually have a constrained layer damping effect. I think it is very effective, gives a much more open and tuneful sound.

Wonderful mate & couldn't have came across this at a better time as last nite I literally was setting up my turntable and along the way talking about the importance of this amazing isolation pad that you've built and with you're kick ass knowledge have helped me to also be able to build a similar platform .. etc your sir are a gentleman & a scholar

My Rega turntable is on a record cabinet i built decades ago, the cabinet is built of 3/4" oak plywood and holds 300 record albums so it is very solid. It also sits within a few foot of my speakers so it's subject to vibration from the speakers and subwoofers in the room. I bought a 3" maple cutting block and also used 3ea 2" sorbothene hemispheres between the block and the turntable feet. The result is very good isolation from vibration, if you tap on the turntable you can hear it in the speakers but even hard knocking on a cabinet is dead silent.

My solution cost a bit more that his dual granite solution but at the time I looked there were no stone boards of the right size available. A 2" think maple cutting board would be cheaper and might well work just as well. BTW always remove the dust cover before playing a record so it doesn't catch and reflect sound down to the record surface.

I used these under speakers to help saved neighbours from sounds transference, and they were *amazing* in conjunction with spikes!

Done this kind of installation years ago : 2 pieces of marble from a construction debris separated by 4 sorbothane feet. Under the bottom plate, a simple rubber mat to avoid scratches to the furniture and add some isolation. You can jump near the turntable, nothing happens.

Great tip! Thanks a lot. I have done it using thick granite plates (43x45 cm) remaining from our bathroom tiling ;-). There IS a difference!

I had a portable dance co. In the 70's disco days and used a demonstration waveless waterbed mattress that was just the right size to hold 2 turntables side by side with about 1" Clarence all around. I built a frame of acrylic with chasing led lights all around . I could fill the platform up at a gig and drain it afterwards. So it was easy to transport and gave better isolation than a 6" thick cement slab. I could actually set my turntable on the waterbed platform on top of my subwoofer and crank up the volume with no subsonic feedback . I now have my turntables suspended from the ceiling with window springs wrapped in cloth.

Great video. I’m currently making a table from a leftover piece of butcher block countertop that’s made from acacia. Can’t wait to finish it and give it a try.

Thanks for the tips I can run my Hi Fi full volume now with no rumble or feed back but I got the granite slabs for nothing ! went to a marble and granite yard and looked in there scrap bin and got two 20cm x46cm x 40cm granite off cuts or sink holes, the bits they throw away after cutting the hole for the sink in a granite kitchen bench . I stuck felt pads between and on the bottom one and it works so well I was amazed

[rogeregisley]

A wall shelf is the best way, I've found, to isolate a turntable and I made sure I installed it as far as possible from the speakers. Every other method of isolation hasn't 'worked as well so far. Even so, I still use an extra perspex platform with sorbothane feet on the wall shelf which has improved the isolation further.

[mattmoshercom]

Swap out the feet on the bottom to coupling feet. Then use a de-coupler isolation feet on the above board. Putting 2 granite slabs can always cause the resonance of the granite to amplify each other to the stylus. A good guide to go by is use a bigger granite mass will do more for your sound floor than 2 thin granite cutting boards. Not saying what you have is wrong but there is some great evidence in Jim Smiths book Get Better Sound about coupling and de-coupling you might want to give it a read. Also put a sorbothane pad under your turntable on top of the top granite board. To test take a small nail and tap it to each board then put the sorbothane pad on and tap the boards again and you can hear the lowered resonance of the granite. Been using that method for a longtime and you will get immediate results of where you need absorption.

I used to granite garden slabs and these anti vibration square feet things. 8 in total. Still had issues though. Realised the weak point is the table it sits on, shakey legs. So moved it to more stable unit. Works good now.

[mostirreverent]

I use a phenolic laminated 1" fiberboard atop a steel table with leveling feet, then 1/4" silicone pads, then 1"x4" laboratory rubber stoppers, then a 1" piece of granite (granite store dumpster throwaways).

It might be nice to try a 1/4 silicone sponge sheet between the granite slabs...

[sega.maniac]

Quite nice ! 👍 But many people focus on isolating turntable from the below point, when technically it should be isolated from any source of vibration including sound it self !!!

[thehandseesall]

Almost great, but to make it great you should swap out the rubber feet from your plinth with sorbathane feet... Would cost you that much more!

[georgeanastasopoulos]

A wonderful, enlightening demonstration. Thank you very much for this choice of a possible isolation platform for a turntable to be put on a less expensive, but efficient isolation platform! I've done research on this topic of isolation for a turntable, and a couple of them are a bit expensive. I have a used vintage Harman Kardon T25 Turntable belt drive; upgraded to a Denon DL-80A MC cartridge. Also I refurbished, repaired Rega Planar 3 Linn Basik Plus tonearm, with AT95E MM cartridge. In may case I'd add one of those platforms, and those 4 isolation feet underneath.🔉🎼🎵

[georgeanastasopoulos]

Furthermore, I was wondering about getting sorbothane material, cutting up 4 square, or round pieces, and placing them underneath the platform.

[stevefredson]

I am embarking on a build similar to this got a chunk of scrap marble from a counter top fabricator. Ordered some adjustable isolation feet from Amazon. My marble is an inch plus thick, 2.5 cm maybe
