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?

All of audio is trial and error. Test and evaluate, tweak and evaluate some more. This is no different. Anyone things a system is plug and play, sorry. This one thing more than anything else will hold you back.

 

On 2nd thought, in this context I presume this trial and error only applies to the Nobsound since they can be run in many configurations, unlike isolation products from other manufacturers. With the Isoacoustics Orea, one can only switch between 3 and 4 footers under a component, that’s about it I guess. In other words, the Oreas can be considered as plonk and play. The Oreas either work or they don’t. If the Oreas don’t work, one cannot do any changes to make them work. With the Nobsounds, if they don’t work, one can change the spring configuration to make them work.

The setting up with Nobsound is also a lot more finicky since adjustments are required with unequal weight distribution of the component. If the springs of the Nobsounds are not adjusted, the component will sit lopsided. With the Oreas (or other isolators), leveling isn’t an issue as the height of each footer is fixed, unlike the Oreas where the height will vary with weight.

I presume the Townshend Seismic Pods are also rather straightforward in their set up without much effort required, perhaps with leveling adjustments they are pretty much plug and play? Assumption on my part.

UPDATE: as to be expected replacing the 2 MD HD springs with 2 Nobs (full springs) under my heavy Core Power 1800 further improved the music. I played both Blues Brothers, before and after the 2 additional springs. Next up was Billie Holiday Greatest Hits.

Blues Brothers: I could hear much deeper into the sound stage and instruments were easily heard where they were physically on the stage and Dan Aykroyd was positioned more to the right and back from Beluchi, and the sax sounded more full bodied than at any time I've listened to this disc

Billie Holiday: This disc always sounded very good, but now, I was transported to the venue, so lifelike

So glad to find this thread. I like to know why things work. The formulas provided help. Although I was doing trial and error, I did get good results.

Chronology:

1. Bought 8 Audiocrast springs on Amazon after the majority here like the results of springs. I picked this brand because it had a higher weight capacity. My speakers are 120 lbs each. Results were as someone said, "right", you just know it. Pretty much same as others. Details, transients, weight, just better

2. LIked the results so much i ordered 8 more for my subs. What once sounded like a single note, had more detail, more and a cleaner bass. At the same time I could feel it. Low notes were the biggest surprise.

So I put these under the four speakers and it worked. Wow! That was simple. And Amazon would take them back if I don’t like them.

3. So what about the amp, streamer, DAC, preamp? Springs didn’t seem practical. Some components are too small and light weight. So I ordered a bunch of Herbie’s Tenderfoots. And the sound went backwards. I noticed bright treble. Bass was not as detailed and more carryover(I forget the word to describe it).

So, I am glad that fine tuning is possible. I have one spring under the speaker that is more compressed. Otherwise, not sure what to do but will fiddle around. Have all winter!

I decided to give the Nobsound springs a try with my MC275 amplifiers. They were already resting on oak plywood bases (home made). I removed the feet and placed the bases on the springs and made sure it was level. Hooked everything back up, started my system and starting streaming the song "Along in Kyoto" by the group Air. First song and I heard details that I had never heard (maybe noticed) before.

I am trying to be skeptical about this, but the next album I streamed had what I can only describe as more depth. It was as if the sound field had depth below the floor. It’s a strange description, but as I was listening it was as if the floor dropped due to the sound field. It’s a weird sensation. It is really difficult to describe.
