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?

@tweak1 Well, I started pulling springs out late yesterday with 3 springs/ 3 Nobs under the Oppo first (decent improvement).

The streamer/DAC I was talking about is also an Oppo105 (heavily modified: clock, improved XLR output stage, IEC inlet, LPS, fuse). The  best result I get with the Nobsounds is 4 units with 1 spring each, springs dampened with ear plugs and bores lubricated with PTFE spray. On the left side the springs are more compressed (as the transformers are on the left). Since I cannot further reduce the number of springs, I will maybe try with some weight on the right side.

@ryder Guess what, I am now on 2 footers with 1 spring in each. 

Have you tried to stick with 3 units and put some weight on your DAC to reach the desired compression?

No I haven't. Will need to find something suitable to be added as weight. That will come later.

I have a rock in my second system phono amp. A rock! From the yard.

👍 Love it. Now that is a cost effective tweak. 
 

I suppose now we need to discuss if a piece of wood might not be better (think Maple Shade)… or what kind of rock. I am thinking Eclogite might be best… or worst… it is heavy and dense. 
 

Sorry, if I didn’t bring it up someone else would.
