dennist Posted August 9, 2021 Posted August 9, 2021 Had a look at a lot of platforms that were either too expensive or too small (my plinth is 50cm X 40cm) Searched the internet, looked at Ikea blocks, granite, perspex etc and finally decided to go slate, got great service from MIntaro slate in Adelaide, this slate is supposed to be the best in the world. Glued some rubber based deadening material on the underside as well, seems to do a good job, I now get virtually no sound through the needle if I tap the stand. 8
wen Posted August 9, 2021 Posted August 9, 2021 I have a slate roof tile seperated by a layer of silicone attached to the base of my turntable , i found this made the most difference compared to sitting the turntable on isolation platforms, was using squash ball glued to whites anti vibration squares, but changed to ecasty props.
dennist Posted August 9, 2021 Author Posted August 9, 2021 Had a look a while ago at those spring feet, might have to give them a go instead of the old brass spikes.
wen Posted August 9, 2021 Posted August 9, 2021 I gave the squash balls on the whites antivibration squares to my brother to put under his Rega planar 3 with Grace 707 arm and Ortofon Quintet Blue MC, his reaction was , " an OMG" moment
Red MacKay Posted August 9, 2021 Posted August 9, 2021 I use 3" of a sandstone slab, (80kgs) a Minus K on top of that and then my 36kg TT. Way lower noise floor and the sound is no longer homogenise. Heaps better. ...Now to fix everything else. 5
Pops110 Posted August 9, 2021 Posted August 9, 2021 I laminated mdf to a layer of wavebar and then jarrah floorboards. Then used Isoacoustics stage 1 underneath. Would be pushing 60kgs all up with turntable on top. 12 1
vinilink Posted August 9, 2021 Posted August 9, 2021 Thanks for the tips guys. @Pops110 I have plenty of left over Jarrah parquetry after flooring was done at my place long time ago. So, hopefully I can give it a try to imitate your isolation stand, but have absolutely zero skills

I know that suspended tables like the Linn generally sound better on a light rigid table. Heavy and heavily damped table supports can make them sound dull. 2

That is a suspension table but whether it reacts like an LP12, I don't know. I recommend a internet search to see if there is any specific recommendations. I've heard that Ikea makes a light table that (sort of) suits Linns. 2
Bass13 Posted August 10, 2021 Posted August 10, 2021 Yea....Ive been a bit slack, been wanting to isolate my TT for years, but still not sure which way to go, she sounds marvelous as is, will use an isolation platform as my Ace card one day to make her go to the next level, if what everyone says about isolation platforms is true, or should I say if it works as good on my TT as others. I did see this which was very interesting indeed. https://www.the-ear.net/review-hardware/esseci-relaxa-750-isolation-platform

Spend a lousy few hundred bucks on an Apollo wall shelf, currently for sale on SNA- and prepare to be shocked by the improvement. I bought a Rega wall bracket years ago, and still have it! 1
vinyl-62 Posted August 10, 2021 Posted August 10, 2021 A wall is the best way to go with turntable isolation but sometimes this is just not possible to some people. I run a Basis 2800 turntable that is located on a dedicated wall shelf and a Garrard 401 that is located on the rack. I wish I could also locate the Garrard on the wall but unfortunately only one turntable shelf is permitted in my shared space. 5 2

Warren Jones Posted August 10, 2021 Posted August 10, 2021 Wall shelves don't always work. It depends on the house construction. I tried a wall shelf when I had the RP8 and it was worse than sitting on the floor. The walls were vibrating as much as the floor but they were vibrating laterally. I now have an SP10 and moved it out of the lounge room into my spare bedroom about 6m away, made an enormous improvement. I am also currently building an isolation station where the TT will hang from shock cord from a 2.6m tall frame. 2

vinyl-62 Posted August 10, 2021 Posted August 10, 2021 (edited) Very secure! It was very well designed and built. Edited August 10, 2021 by balk2117 2
Gambit 1870 Posted August 10, 2021 Posted August 10, 2021 How well do these work on cheapy TT's like debut carbons?

lumholtzii Posted August 10, 2021 Posted August 10, 2021 The thread started with a granite slab, and I've used a different variant of that approach by getting a local kitchen bench mob to use an off-cut (e.g. the sink hole) and get them to trim it to size and edge it. Lots of colours to chose from, and In hindsight perhaps I should have gone with a darker colour. Cost was $100. Perhaps you'll do better I've tried the squash balls underneath, whites squares and I'm currently using 4 x magicahexas. Best yet, and overall a pretty affordable approach. https://www.decibelhifi.com.au/agora-acoustics-magichexa-each/ ... in fact I've got them under pretty much everything. Perhaps I'll try isoacoustics or still points one day, but really atm I've never had a problem with it sitting on heavy cabinet and then directly on sprung timber floor that is highly resonant. If someone thumps on the cabinet or jumps up and down on the floor there is no audible effect. Good enough for me. 3

They work well..
Red MacKay Posted August 10, 2021 Posted August 10, 2021 46 minutes ago, Stump said: Did you need the sandstone slab to get the correct weight balance for the Minus-K.? They work well.. No. I bought the sandstone previous to the Minus K as I had horrid feedback issues with this TT. A fried lent me 4 small mudstone tiles and they fixed 90% of the issue, so I went one better. It was cheap (under $200 from memory from Gosford Quarries in Clayton, Vic.) and is the same sandstone as they run under all their test gear at Monash Uni, so I figured it was good enough for me. ...Then the Minus K turned up. What a revelation! Instant noise floor drop - even a half going deaf old fart like me can hear it. But the best was how the soundstage was no longer 'homongenise. All the players and instruments were more on their own and a beautiful smoothness to everything. Only problem is my Minus K is rated for around 38kgs and my TT is 36kgs, so it's really on it's limit. I might have to look at a bigger model down the track. As I said before - now to fix everything around it! 3
Tax Posted August 11, 2021 Posted August 11, 2021 Depending on budget, the Minus K and Vibraplane are really good isolation platforms I used the 60kg Vibraplane under my Micro Seiki TT. The TT and platform weighed approx 130kgs. I use Isoacoustic Gaia's under my Garrard 401. Initially I had the Gaia 111's but the change to Gaia 11's was a significant improvement. So when using Gaia's probably best to go the next weight category up. For the Commonwealth TT build I had the feet custom made in 316SS in 60mm which will sit atop the pneumatically isolated Vibraplane. At the budget end things like Herbies work well under smaller TT's. I have used those under my Thorens TD160 and Luxman TT's. Experimentation is key. Good luck! 4 2
