the granite things on your link are only 8" x 8" trivets.
Good idea 👍😊
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.
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
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!
Great tip! Thanks a lot. I have done it using thick granite plates (43x45 cm) remaining from our bathroom tiling ;-). There IS a difference!
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.
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
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.🔉🎼🎵
This is so great thanks for sharing! Build one of my own now
You're very welcome. Let me know how it goes.
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.
Since your one of the latest post, what are sorbothane feet and where can they be bought in USA. No am_z_n. Thanks!
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.
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.
Photos or it didnt happen.
You sir are a genius 👏
ha i had this thought too! thanks for implementing it :) i will follow the same
This is a really good tip Thank you
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...
Thanks! (Pasco, WA - USA)
Did a lots of this kind of DIY to my old days Sony single bit CD player
Great job.
Excellent!
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
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!
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.
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.
Used a Target wall stand £45 32 years ago. Modded by removing rear 2 spikes and making it 1 rear spike and 2 at front.
MDF that comes with it glues 2mm thick steel pressing off cuts to underside so spikes bed on to.
Ultimate make a Y frame from steel something like 80x8mm thick and weld up. Drill and tap for 3 spikes and sandwicj between Target stand and MDF.
Only used sorbothane when it came out then to reduce a tad of vibration from platter to tonearm in the cutouts and around the motor. Scrap the sorbothane and go hard isolation using spikes on to spikes and experiment doing the same with the budget Rega.
You are both right about wall shelves. I think many, if not most, people looking for turntable isolation have problems with footfalls. No isolation platform will cure that problem. Let me add that a wall shelf needs to be screwed into the wall studs. And if you can, use an exterior wall where the studs rest on a foundation, which is about the best mechanical ground available. And here in the US (Detroit, BTW), suspended floors are the norm and using an exterior wall will completely isolate the shelf from the bouncing, vibrating floor and any furniture resting upon it. I have a vintage (1989) Linn LP12 whose suspension is notorious for its sensitivity to footfalls, making the turntable nearly unusable when placed on floor standing furniture. A wall shelf on an exterior wall allows me to break dance (at least when my knees were still good) right in front of my LP12 without it missing a beat. Another unspoken advantage to a wall shelf that when mounted at an appropriate height, it is far easier-and safer- to manually cue the tonearm then when you are bending down and over the deck.
Sorbothane with size calculated for the weight bearing would be a massive upgrade to this. Also Black granite is harder, you can get them in Tesco!
Mark Manning it is supposed to be the daddy and I have ordered some sorbathane pieces to experiment with but it's costly too so I'm looking at making some custom ones out of silicone.
Great video about isolation ; I was about to make this with another aproach but yours is definitely better. I’m stealing it ! Thank you.
It's all yours :) Thanks for the kind words. Let me know how you get on.
Nice job. I'm looking to do something similar for a telecine project as having issues with camera picking up the slightest vibrations. I cant find the adjustable coaster feet you mention? Do you have a link to them?
this is cool fella....good work 👍
Thanks so much... will be doing more videos on Vinyl very soon. Breaking some of the myth on the snake oil BS options, upgrades and gadgets also and how to do it an awful lot cheaper.
SamsungNow
no problem fella.... yeah came across your channel as I'm picking up a new Samsung TV tomorrow and I've been looking for some picture settings to use with the ps4 pro.....anyway I dropped u a sub as it looks like u got some good and useful content
I appreciate it thanks. Please make sure you watch my video on not updating to 1180.5 on the TV. If you are getting a KS.
SamsungNow
well it took a while but I managed to convince the wife we needed 4k, and she eventually said ok but if she had a say in what TV we got (what's that all about lol) and she liked the look of the mu8000, so that's what we're getting
SamsungNow
well I say it's the mu8000 but it's actually the mu7000 but it's got the one connection box thing and the cables go through one of the stands.....so I think it's the mu7000 in here in the UK/Europe but it's the mu8000 everywhere else.....when I looked on rtings it's definitely the mu8000 but in the shop and on Samsung website it's the mu7000......it looks like the ks8000 and not any of the other mu series....does that make sense lol
Furthermore, I was wondering about getting sorbothane material, cutting up 4 square, or round pieces, and placing them underneath the platform.
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 !!!
It should be installed in another room with the audio cable passing thru the wall.
Will try this n my Project Elemental TT with 2 round granite boards, I have one just need to get another and wait for my adjustable feet to arrive.
Works a treat and saved me a fortune. Let me know how you get on.
Done and if nothing else doesn't look half bad! there are "some" sonic gains however.
What feet did you get and where did you get them?
The real test though would be to tap on the rack below the homemade platform and hear if your tap transmits through to the cartridge and can be heard while its playing, correct?
Are you thinking of any upgrades to the turntable. You better off getting 3 -4" open-cell cellulose foam and gluing it to the bottom of the turntable or just placing plinth on top take the feet off, make sure the bearing is tight against the foam just put a cross in it. it is an awful bearing, a worthwhile upgrade to any turntables to get a squash ball fill it with enough tungsten powder and Super Glue it over the bearing to the plinth make sure the tungsten powder is right to the top you can make a small hole for small funnel to go in on the side and a bit of blue tack to block the hole the hole has to be at the top not the bottom. and enough at the bottom covering the bearing. should be alright in your case that's the best upgrades for any bearing. you want to replace the bearing on yours for a thicker spindle go for a 12 mm minimum inverted bearing.
Got the standard cartridge you can get what's not cheap a micro linear stylus is best you can get the audio Technica atvm95ml £150 but you might as well by the cartridge it comes with it it's the same price. Failing that the nagarkar mp-200 is a very good cartridge moving iron and Compliance is suitable for your arm. I would take the rubber feet off between the two chopping boards and replace it with balls of blu tack is the best better than rubber or sorbothane rubber. In test is the best isonade in all tests. Put some open cell foam in those feet on the bottom are they hollow
Nice hack! Do you think the adjustable feet are not necessary if you already have a perfectly level rack? So just rubber feet instead?
By Jove, I think I've stumbled upon a genius!
Done a better job 31 years ago cost £1, compared it to expensive stuff and blows them away.
wow...you weren't kidding about not level....but great video.
I.bought.two,granite.slabs.2.inch.thick

which is better? 3 feet or 4? I notice the turntable only has 3.
If you ever want to make a 2.0 you could try to invest in 4 plastic tubes, 8 magnets and a steel plate.
place the 8 magnets, 2 in every tube so they repel each other, place the steel place on top for magnetic isolation.
The magnets shall repel with a force that perfectly balance the weight above plus something, so the magnets do never touch but still do not "vibrate" to much.
In theory a good idea. But it won't be stable enough and the magnetic field will probably cause problems with the cartridge.
@@nielsv2025 thanks so much for replying, I think you may be right, unless you can shield the magnetism in some way.
I imagine you by stability are talking about the sideways motions and the "flex" there is between the magnets and the surface, so it can bob up and down? :-)
@@friedmule5403 Yes, that is what I mean. It may cause up and down movement, a little like springs. About the magnetism, I guess if you'd be able to perfectly shield it it won't be a problem. But for somewhat heavy turntables you'll need some strong magnets. Especially MC cartridges are very sensitive for magnetic disturbances. One of the reasons the motor is always placed on the opposite side of the arm. Even the small magnetic field around a motor can cause problems. In my humble opinion mass and decoupling motor from platter is still the (easiest) way to go.
@@nielsv2025 Yes that makes a lot of sense, what if the magnet was surrounded by either a copper tube or maybe copper wire, mounting a resistance that can dampen the movement, then place each of the 4 magnet feet in opposite pole on the underside of a metal plate?
@@friedmule5403 I'm not an engineer but what we see in modern turntable design is either the Rega approach, so very light and stiff, controlling motor vibrations with dsp power, or using simply mass, mostly with the motor separate from the platter. Basically. The 'floating' approach like we have seen in many turntable designs in the past like Thorens used to do is not used or not used frequently anymore. Using magnets is some form of creating 'floatation'. So even if it would work to completely shield the magnetic field , and/or what you suggest above, it would still not be as good as the more modern approach. Another problem I can think of using magnets is that of course you can use magnets on every corner but the turntables point of gravity will not be in the middle. So for that to work you need to calculate exactly where the gravity point is to distribute the forces evenly. That's all possible. And if this, and all your suggestions were the best possible solution to the problem I'd say it's worth it but according to modern engineering it simply is not.
Will an isolation deck like yours prevent fedback humming loop sound?
Very nice! What is the coaster type thing that you can adjust for leveling? Can you describe it a little bit more please? Thanks
Just saw this video. I am looking for the "furniture coaster feet" you are using. Exactly where did you get them because I cant find anything like them that adjusts it level. Appreciate your source for them! Thanks!
Looking for the feet as well

Replace the plinth with granite so making a really heavy TT.. My 401 is totally encased in granite and weighs around 220kg. It takes a 3 man lift.. The platter also has been replaced with steel and copper disks and this all sits on a minus K not hundreds but thousands you have a lot to learn.
Thanks for the tips, I’m curious have you considered bulking up the turntable base? Rega make their bases from MDF, I imagine to bring down costs. No reason therefore for owners not to improve on the rather flimsy foundations to provide extra solidity by increasing the mass.
The whole Rega TT design philosophy is low mass though not high mass.
It's actually phenolic resin, not MDF.
Did something similar for myself a little while ago. Researched everything first and then went to work. According my research of these tables you could better yours by:
1. No molecularly tight material in plinths as it doesn't absorb nor dissipate vibrations well... use MDF instead for example (it's inexpensive as well)
2. Use sorbathane feet in the upper plinth for reduced transmission from upper to lower plinth
3. Use spikes in the lower plinth to minimize vibration coming up through floor
Hope this helps.
Of course if not... wall shelf it!
I have a question.
Would this work for wood flooring? I have my turntable on a wooden table and anytime I get up and walk past, the record skips due to the vibrations from the wood flooring. It’s very frustrating especially when my wife does it.
Thank you for this. Could you tell me the name of the larger adjustable feet on the bottom? I'm trying to search for them.
that looks like SVS subwoofer isolation ?
Did you ever find them? If so, what feet did you get and where did you get them?
If you want good cheap isolation look on amazon for washing machine isolation pucks, they go under machines to cut down vibrations, about £8 for pack of 4. Not sure of $ price but would guess 10.
Do these 8" x 8" Stone Granite Boards really fit under your turntable? 8" seems it would be too small to fit under your turntable. Curious before I buy two of them... thanks!
Ethan Wolf
I like the idea of this but these size boards wouldn’t fit under my audio Technica so didn’t work 🙁
I had the same thought and can see that an 8x8 piece would not work
Hang it from the ceiling
Even better and easy to do use a wall shelf 2nd best
I wouldn't exactly say hanging it from the ceiling is easy for most people to do. The idea was as a means of a quick, easy and cheap fix to a common problem.
Not a good thing at parties. Trust me. lol
czcams.com/video/za4WOFv5E7A/video.html - I highly recommend checking Mr Scruff's DIY isolation for huge venue PA and scratch turntable isolation. Since I have my decks on top of MDF Ikea Besta (183cm TV unit) on top of an Expedit, it won't take that much weight I think (not much more than Xone 92 & two or three 1200's anyway) so I can't really put anything too heavy on there. So thinking Auralex Iso-Tones or Luke Absorbers are a good way to go. I wanted to use from Australian store Bunnings $15 concrete paving slab rectangles, but 15KG each, I don't think my 'booth' would take an extra 30kg. Really need a sturdier base with steel I think. I heard Granite isn't that great through some heavy forum reading about the subject.. some people used it but a lot recommended other materials.
1000th viewer right here.
naah mate, try roller blocks or inner tube method, they work even better
What happened to your shop?
Is there really a sound difference?
Yes it's objective what I suggested is better way and use bamboo but important is how it's situated the turntable you want it on a firm heavy platform weighing at least 110 kilos or bolted to the wall
@@johnsweda2999 I have the Music Hall Ikura and the table comes isolated from the bottom platform. Do I still need to isolate it more?
@@arielrodriguez6980 what do you mean isolated from the bottom platform that's not the multi-layered one that's a solid plinth with. strange looking feet. And yes it's still better to and some more isolation and dispersion platforms
@@johnsweda2999 I mean it has rubber spikes at the bottom platform and above the platform it has more rubber spikes and the turntable sits on those rubber spikes. You can see it here with picture 9 if you click on the black one.

sorbothane!
Okay George Harrison
K
You should of gave us the knuckle rap test. By hitting on that cheep table the TT is sitting on
Glass is a big no no also to use. So i see the platter Looks like its glass. Go Buy a VTL TT all american made. And sit it on a 4in. Mapleshade maple block unfinished wood WITH your home made feet
No marble
The P2 is a pretty decent Turntable for the money and Rega know a thing or two about them. For the money it's a good turntable. Of course you can start adding things to isolate more, but the idea is to keep costs down.
I agree that the Rega P2 is a very good TT for the price point.
Your method of isolation is a good one, I thought about using 16" square concrete pavers to do something similar but I couldn't find the pavers in the wintertime.
I now have a Rega RP3 sitting on a 3 inch thick 12X18 inch maple cutting block with 3 sorbothane feet under the cutting block. This is all sitting on a 42" record cabinet that I built out of 3/4" oak plywood, I had to put 1/16 inch shims between the front sorbothane feet and the cabinet to level everything out.
I wanted to use these but too heavy for my Ikea Expedit and Besta on top of that xD bunnings.com.au/anston-600mm-x-450mm-rectangle-concrete-paving-slab_p3451557 I wish I had a solid/steel booth
"The deck"? Man, I am out of here!
i'm sure steve hoffman will take you back
I'd like to be nice but I take hifi seriously as an audiophile. Don't take it the wrong way but this ain't doing much and looks ugly I've had various turntables and other stuff along the way and learnt a lot but you need something more soft like silicone feet or magnet levitation there are cheap options out there even cutting a bouncy ball in half you only need one solid piece of material under which can have "rubber" style feet but then use better feet on your turn table or you can buy vibrapod Isolators. Hope this helps .
Keep the bloody camera still..! Just set it down and leave it alone.
