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?

Bkeske, this is the layout of my amp. Now I realize why it’s heavier at the front. The transformers are closer to the front.

 

Nobsounds on my amp. I managed to reduce the gap to 3.5mm at the front. 2mm gap at the rear.

I gotcha, nice Lux. Yes, your layout is a bit different as it is an integrated, not a stand-alone amp. The shots of mine are on my virtual system page. I use the Nobsound feet under the chassis itself, not to its stock feet, but instead, adjacent to them. I should probably remove the stock feet actually.

I had been using cones prior, which did make a significant difference. The Nobsound vs the cones I was using is pretty much the same/similar actually. Perhaps a little better, but not anything that ‘turned my head’ over.

Or I can just set my entire system on a set of box springs.🤣

 

 I do like the idea of damping the springs. Thinking that a coat of rubberized paint that the spring can be dipped in. I know, I think too much.

No I sprayed 50 springs with Flex Seal and then used ear plugs inside the springs. It made quit a bit of difference.. It actually works perfect for lighter stuff like turntables, amps.. Speakers I notice it a lot less. The springs do it for the speakers alone. I load some gear with springs and a block of wood on top too. I load it in a slot between 2 3/4" pieces of 13 ply birch. Tinkering..
