Plinth feet for my Turntable - Which ones?

[The Black Adder]

Hi all.

My Thorens TD124 is in a heavy plinth. It's also coupled to the plinth with the rubber grommets removed to which I find to be very beneficial.

I've now got coming to me an isolation platform and would like to know which feet are best for both plinth and platform.

A little simple diagram:

____------|------___
============== < Turntable
^ ..........................^ <Feet

============== <Platform
^...........................^ <Feet

I've been looking at some examples of feet but confused in which ones would go where as I've never had an isolation platform made before:

There is one thing I do need, the platform would need height adjustable feet.

Budget, well... I don't want to go mad as there must be something out there at a reasonable price which work well enough and look good too. Some isolation feet are bonkers prices and I'm sure they need not to be.

I'm not interested in heavy jewelry either, not my style but must look nice and not home made if that makes sense? Screw in thread would be best and feet that don't have multiple parts would also be best but not essential.

Some of the places selling these things don't really tell me enough information which is a little annoying too
so any other options and experience to my findings below would be most welcome as well as any opinions/views of best practices using feet.
So, first up:

I know this is not what you want to hear, but for best results with a record player like the Thorens, hard couple it to a proper isolation platform. That means a platform heavy enough to absorb and dissipate vibrations coming from the deck (and there are loads of those with a TD-124). Then, you need to isolate the platform from the myriad vibrations coming up through the floor, walls etc due to footfalls,washing machines, passing pedestrians and road traffic, etc, etc. The only way to isolate is with a proper spring system, calibrated for the weight of the deck and the platform. Spikes, string, sorbothane, gel stuff do not provide isolation down to the levels that matter with what Roy Gandy calls a vibration measurement instrument, eg the record player. Springs may seem an easy matter; indeed the maths is easy enough, but creating spring supports with optimum stability and sensibly applied damping is something else.

You could go round in circles for years trying to avoid buying something that works straight out of the box to satisfy the criteria outlined above, but Townshend's Seismic Platforms do work, and in the case of turntables, magnificently so. They provide near full isolation, with good inherent stability, in a very slimline and discrete package. No, they are not cheap, but My Goodness they work; and Townshend will change the pods to a different load rating if a customer needs something different down the line! Not a single person who has tried my demonstration Seismic Platform has declined to buy one.

Hi Hugo.

Thanks... yes I remember asking you before about this, lol ... The only problem is this, the price... lol - I can't understand why the platforms are so expensive. To me it's crazy money.

I'm really quite happy with the sound from the TD124, always have been. The characteristics of the deck in how it reproduces the music outweigh the small things.

But because I have my amp next to it I do get a very small mechanical hum from it so I had a platform made to isolate the main deck slightly. Whilst I was looking for feet for the platform I thought I'd find some better ones to replace the standard rubber ones on my plinth too.

The Townshend pods are great, had great reviews from yourself and others but at £90 per pod it's just too much at the moment so I thought I would look in to other feet.

I know I'm not going get absolute perfection here but this is a journey for me so I thought I'd might as well try things before I dig deeper.


.... a little question, Hugo... What weight seismic pods do you use? I think they go from A to E?

Thanks, Al.

They have always been of fascination... Not sure where they would be fitted though.. Do you use them?

[DarrenHW]

I have Trans-Fi feet (priced individually, but still a bargain) between the 2 slabs of slate that make up the plinth for my 401. Due to their size they are a joy to adjust, they turn easily by hand with no need for spanners, allen keys etc... They're are very well machined and IMO look amazing. My only small complaint is that the o-rings have perished, the same is true of the ResoMat, but unlike the mat they can be easily replaced.

Track Audio make a specific set of isolation spikes for use with a turntable, originally with a spike but then a later a built in cup to protect surfaces. Both worked well.

Price was about £400 for 4. Beautifully built, fully adjustable and worked a treat.

Not sure if they are still trading, but worth looking into if they still are.

[Dubster68]

Used the Trans-fi feet and the build quality is amazing. The guy who makes them is very helpful to any enquirers. Very easy to adjust and also look amazing. They are very heavy and can be machined to your own spec.

Not used personally but some members on here have them , I was impressed with the youtube video

I'm not actually using the TD-124 at the moment - it's going to be gently refurbished/serviced and then sold since I don't need so many record players! That aside, the Townshend pods that I did use under the TD-124 with its heavy Swissonor iron platter and solid Jim Campbell plinth are 'Yellow B' load rating (max 8kg). For a regular Mk2 TD-124 with alloy platter, I suspect that the orange 4kg pods would be better. Even better than that - the Townshend Seismic Platform does actually work superbly under a record player and need not cost what you think.

[Primalsea]

I believe that with something like the TD124 you need to go for mass all they way. This means direct coupled to a heavy plinth that has good solid and heavy feet that sit on a good solid and heavy unit or wall shelf that has plenty of weight that is fixed to solid wall.

My garrard sits in a heavy slate plinth and the feet are metal tubes filled with plaster. The complete TT sits on a wooden side unit that I lined with 25mm MDF and now weighs so much I can’t lift it anymore.

Thank you for the recommendation, here's a hifi world review.

HI, give the Soundeck DF damping feet a try, I'll give a full refund (less postage) if you don't like them.

I use the pads under my Gyorbe and under my speakers. Rheyre brilliant. Highly recommended.
