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?

Alright, thanks for the advice again.  Will not rush it.

Why not try one footer centered at the rear with 5 springs on it? There are manufacturers such as Esoteric that have only 3 factory installed footers under their disc players.

I’ve Nobsound springs under 11 pieces of equipment. All with 3 footers under each.

I just picked up 2 new sets. That is my approach too Brian. Thus, Now have three sets = 4 pieces of equipment. Was just playing around with spring counts on my Belles 400A this afternoon, which is a beast. Started with three springs initially, but added a 4th spring to each of its three today (in the center).

I’m just unsure and a little wary of the potential danger due to the 63 lbs weight of the unit. It has heavy duty cast-iron insulator feet which strongly support the component. The bottom plate at the rear middle may not be strong enough to be used as a support. Furthermore, there are air vents at the bottom which extend close to the rear of the unit. It’s a Class A amp.

 

If the component is less than 20 lbs I wouldn’t hesitate to use 3 footers as a support. My DAC is rather lightweight at 15 lbs, and 3 footers with 1 spring each may be too much.

 

I haven’t tried the second set of Nobsound on my DAC yet as I want to evaluate the performance of it on the amp first. I have to say, initial impressions have been very positive although the set up may not be fully optimized.
