Hi guys

Can anyone recommend some cheap isolation feet for a TT?

I've been looking at these on ebay:

It says - "Application: Set up the spikes beneath the equipment as same as the demonstration. No drill is needed. No adhesive substance is recommended, as it may influence the isolating effect."

If there's no adhesive used or connection to the plinth, etc how easy is this going to be to set up and height adjust without an extra pair of hands, or am I having a blonde moment :scratch: Does anyone else use anything similar?

Cheers. P

Do you mind if I throw in a question (it's kind of on topic) here? :eek:

If you were to use something like blu-tac to increase 'contact' would it be to the detriment of the item? If you weren't to use blu-tac, would you use anything else, or just the item by itself?

I would also like to throw in a question, as i really "question" the isolating effect of a brass plated metal stud?

Please explain! :mental:

But i would also like to recieve some tips on isolating feet suitable for my SL-150 MkII, basically quite similar to ever popular Techy SL-1200 ;)

I've had a look at the Isonoe, and they seem to do their job based on visual inspection. Never tried them though.

Some decks like a rubbery decoupling kind of thing (the 1200mk2 techie?) and others a direct coupling as above. Since the support is king here, either technique could be tried?

With these types of device it's horses for courses and one man's meat etc. You need to try some with your equipment and hear if the effect is right for you. I don't think there is a definitive answer.

Try the Vantage Audio feet (http://vantageaudio.com/info/sp10acc.htm) Mike. They are as good as the Isonoe's (some say better behind closed doors :D) and they are only 25 quid a set. Granted they don't look as flash but I think they sit very well with the Techies aesthetics... :D

I use the brass supports mentioned in the OP under granite chopping boards as equipment supports. I've tried them unsecured and secured with epoxy and I can't detect any difference. The home made isolation platforms work excellently however and at a fraction of the cost of commercial models. Incidentally, you only need three feet, two to the front and one to the rear. This does the same job as four but makes the unit a helluva lot easier to level ;)

These are worth trying

Hi Chris,

Welcome to AoS - good to see you here :)

How much are the PABs, and does the thread fit exactly into the slots on the underneath of a Technics SL-1210?

Hi Marco,

The standard thread size is 8mm, but "made to measure" also available.
£249 for set of 4

I suppose it will depend on the OP's definition of the word 'cheap' :eyebrows:

Thanks for that, Chris. I'm not sure what the thread diameter is on the Isonoes I'm using.

It'd certainly be interesting to compare the PABs with those, but they'd need to have the right threads :)

Indeed, but it's nice to have a viable alternative to the Isonoes, at the quality end of the market. If Chris has a demo set, which are suitable, I'd certainly do the comparison and report my findings here :)

I think you're right, dude. The ones on the PABs then are just a bit too 'chunky'...

Not exactly what the doctor ordered, methinks.

The other issue having tried the Track Audio Islolation Feet, is if they are too heavy and the TAs were, they will pull the metal threaded insert out of the bottom of the Technics TT :( Its only friction fitted into hard rubber.

Those feet in the photo do look very interesting though regardless of whether they fit into a Technics TT or not.

Marco,

I have feet and platforms on free trial.
Don't mind sending you both for trial.

Hi Chris,

If you can get M6 threads, I'm up for it :)

You can unscrew them and put your deck direct on the feet.

Hi Chris,

As my deck sits on glass shelves, that would make things rather slidey and unstable. I wouldn't feel happy with that, in case I bumped it and the whole lot would slide off and fall on the floor... I'd like the rigidity that screwing the spikes into the base of the T/T offers.

Can you do me some with 6mm threads? If so, I'll give them a go! :)

Marco.

Interesting options there, methinks... I've heard very good things about Ceraballs and the other Finite Elements series of vibration isolation.
And these Fidelity Arts seem to follow a similar route.

But, to me there must be a very different task to isolate a 10kg t/t rather than a complete rack for equipment weighing in at around 80kg (estimation of my current setup)

And also, isolation mostly focuses on a specific resonance frequency, such as NoVibra for low freq resonances and Ceraballs for resonances higher in the freq spectra?

Whats your opinion on this?

Morning guys,
>>>Mike
In each PAB feet there is a moving ring of ball bearing. Each feet can support up to 60kg ( 4 feet -240kg).
I do agree with Mike. I haven't found isolation product yet, that works in all frequences. I use feet to support heavy weight and platforms under lighter stuff. Works very well!
>>>Marco
I'll double check the sizes and get back to you.
