Springs under turntable

Hello,
I got the delivery of Solid Tech Feet Of Silence footers this AM. The delivery was lickety spilt, all the way from Sweeden and I didn't have to pay any Customs duty for this purchase. The footer design was excellent ad it does move in all directions as advertised. I have just installed three footers underneath my Clearaudio turnable and listened to it. The sound was ok without much adjustment. I have to do the load adjustment tomorrow, which is really the key and see if it addresses the footfall issue. If it does then I have found a commercially made spring isolator which isolates above 2-3 hz at least in the vertical direction. I would keep you all in the loop,
Thanks.

@indranilsen Hopefully they'll sound better tomorrow. Thing is, they are a lot more expensive compared to the Nobsound at $35. How do they compare to them?

Rix, a turntable suspension is just a simple mechanical filter. The trick is setting it up so it is stable. As for subwoofers the trick is to give the driver a perfectly solid enclosure with an infinite mass. Not so easy. Put your hand on your subwoofer enclosure while playing something bass heavy.
Any fibration you feel is distortion. That vibration is either from the enclosure walls moving or the entire subwoofer moving. In most cases it is both. Ideally you should feel nothing. You can not isolate a subwoofer from the house. Bass is insanely powerful. Put on a 30 Hz test tone and turn up the volume. Your entire house will sing at 30 Hz, glasses, plates, pictures, the walls, your teeth, everything. Fortunately for us our brains can only pay attention to the loudest noise. With music and the satellites running you can't hear it. If you don't want to hear your car rattle, turn up the radio. The medical term for this is "masking"
I had an older S5 V8 with a manual. It was hands down the prettiest car Audi ever made and a very satisfactory daily driver. 

Nobsound springs arrived today ( day late).
Set up with just three springs in each pod and used four pods under the 401.
Checking compression and height of plinth it looks to be very even all round despite the fact that it has a pretty weighty motor at rearcenter left.

Immediate impression with an album I am familiar with is somewhat increased bass although possible it is a bit more muffled/ muddied.
But very early days yet.
Not sure as I would say I am noticing much more detail level increase but it’s certainly no worse.
Mids also feel a little fuller but again maybe not quite as "tight".
No other changes at this time like mats etc, just spring pods installed.

May set the other set of pods up with just two springs each and try that out.
My 401 is not as heavy as noromance and maybe need to compress these spring pods a bit more.

Two springs does not work as it just wobbles like jelly...lol.
So went to one spring in center.
That compressed the pods too much so back to three.
Interesting experience.
