Nobsound springs - load range

I want to try out the Nobsound springs as damping footers (mainly under my mono blocks and my streamer). I ordered a first set of them and now I wonder about the amount of springs to put in for different weights of equipment.I remember one post that said it works best when 50% compressed (was it @millercarbon?).

I measured the compression of the springs, it takes ~2.5 kg per spring to compress it to 50%. Based on 50% compression target, this yields the following sweet spot configurations (only stable ones, total equipment weight):
- 3 units, 3 springs each: 22.5 kg
- 4 units, 3 springs each (or 3 units, 4 springs each): 30 kg - 4 units, 4 springs each: 40 kg
- 3 units, 6 springs each: 45 kg
- 3 units, 7 springs each: 52.5 kg
- 4 units, 6 springs each: 60 kg
- 4 units, 7 springs each: 70 kgLoad can be considerably higher than expected (somewhere I read about 36kg, which is presumably for 4 units).

Any comments?What about ~10 kg streamer, seems to be too light to compress the springs enough? Does anyone have experience with Nobsound springs under light equipment like this?
Based on your experiences: Would you even dare to put an 80kg floor standing speaker on Nobsound springs?

   Appreciate the idea. It makes sense to me to try and reduce transmitted vibration in some way that does not affect the action of the spring. Of course, I also wonder what the effect might be by the manufacturer to use other alloys for the springs themselves. Maybe different metal for the center spring if used.

@ryder The springs under your Luxman are too compressed.

 

May I know the recommended compression? I was made to understand that the optimal compression of Solid Tech footers is between 1-3mm. The Nobsound is based on Solid Tech's design so I presume it’s the same.

The gap at the front footers is 3.5mm. The rear footers are worse as they currently have a smaller 2mm gap. If the Nobsounds require a larger gap I’ll add one spring to the rear footers which will probably get the gap up to 5mm.

When I first installed the Nobsounds, they have a large gap between the top and bottom aluminium piece but a member here advised to get them as close as possible. Check out the thread at the Tech Talk section.

@ryder I ignored that sheet and load by ear. Mine have less compression and sound best when they bounce.
