I'm thinking that I need an isolation platform for my TT. What are people using? Recommendations please.

What TT are u using? Idler and belt drive may require different approaches.

In general constraint layers usually work well…try to avoid mdf, sorbathene, blutac and spring.

Happy New Year from Scotland.

My PT Anniversary deck has a very lively suspension and is highly susceptible to footfalls, the designated area in the living room is a suspended timber floor which no amount of repositioning could take care of unwanted vibration.

The solution was to install a cantilevered Finite Elemente Pagode Master Reference wall shelf. This also involved fitting the shelf on an interior load bearing wall as the external wall is dry lined, a compromise but ultimately successful work around.

Grand Prix Audio also had an interesting design, neither is cheap but they are effective isolation platforms.

Did you get the True Point upgrades?

Hello there.

If you wish, PM me with a the weight of your TT plus plinth, and I would be happy to get some appropriate Stack Audio AUVA EQs to you, when the ones which are presently out on loan come back.

If you PM me, let me know where you live on the Mid North Coast. I live in Sawtell, so organising a trial for you should be pretty easy .

Won't be for a little while because three people are in the process of trialling them, including use with TTs in at least one instance.

Best wishes,

Paul.

I'm about to buy some of the Auva 50s for my turntable. They look like pretty good value and have a money back guarantee if not happy.

No, only a new belt and a clamp. Everything behind the scenes as it was when I bought it.

I went down this rabbit hole a few years ago. My TT now sits atop a Minus-K in another room which makes a significant audible difference. I understand a Minus-K is expensive and not in the budget of everyone.

As @theophile said a turntable has the resolution of an Electron Scanning Microscope. Any vibration will blur the image. In a picture this is easy to see but in a vinyl playback system this blurring of the sound is much harder quantify. The easiest way is to use a stethoscope and place it on the tonearm mount. If you can hear anything then the cartridge will also hear this. When I started this I placed the stethoscope on the mount and I could hear my wife talking in the kitchen, YES the plinth was acting as a receiver and amplifying the conversation. I then put an oscilloscope on the output of the phono preamp and placed the stylus on a stationary LP, you guessed it her voice was visible on the scope trace. I'[m not suggesting you put your TT in another room, my point here is that the TT is one of the most sensitive vibration measurement devices ever made and isolating it as best you can will have positive results.

Making measurements is easy with a Behringer or Focusrite or any other USB sound card monitoring the output of the stylus on a stationary LP. There are free scope apps for Windows that can be used.

Keep in mind low frequency is your big enemy because of the RIAA correction in the phono pre that amplifies low frequency and attenuates higher frequencies.

I started out with those cheap e-Bay spring sets and performed some measurements, which can be found here.

The Stack Audio Q1 Platform is nearing release and will be available for purchase soon. Interesting design approx 52cm by 43cm by 4cm high......comprises 35 isolation shells similar to the current AUVA EQ technology.....these are sandwiched between metal panels top and bottom. Weight load bearing is very high KG-wise. The AUVA EQ devices should NOT be used with the Q1 platform ...your component sits directly on top of the Q1 Platform.

I have placed my order for my Q1 and am eagerly awaiting its being released. The Q1 will certainly exceed the $1000 AUD mark so I am facing an extra import charge from the Australian Border Force. Stack Audio use FEDEX so the import fee is payable when the Q1 Platform enters Australia. Around 10% of the items stated value plus an admin charge.

Cheers

Some months ago I changed from visco-elastic footers to aluminium cones as footers for my equipment. I did this after playing around with some spare cones under my monoblock amps.

In my concrete slab floor apartment, I liked what I heard. So everything got alloy cones, even the turntable.

I then changed my stand from a welded steel affair to a plywood interlocking one. No change to footers.

On the weekend, I happened to tap the shelf of the stand the turntable was sitting on and could hear it clearly through the speakers. No surprises really and there really isn’t too much structural transfer that I can tell given the concrete box I live in.

Given the turntable sits behind and to the side of one speaker, airborne transfer to the stand and table is likely.

So, while the table is still likely to receive directly, I sought to minimise vibration from the platform the table sits on.

A few tools, some spare Sorbothane blocks, a sheet of Dynamat, and 30mins later, I had this for the table to sit on:

Very effective indeed and, essentially, zero cost. I may try different footers as the opportunity arises.
