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?

I finally got around to taking my Emerald Physics 3.4s off the Harbor Freight dollys they've been on since I got them over a year ago. Each base is resting on 4 full spring Nobsounds. Quite an improvement!

@noromance 

richer tone from top to bottom, especially in the lower mids and bass

 

Also due to the added height of the dollys the sweet spot was too high, now where it was intended

@ryder

I am using them without experimenting with removing springs (though thanks to this informative thread, I will-eventually) and my system sounds amazingly better than when I was using Machina Dynamica cryoed and heavy duty springs

 

As to experimenting, if you have any kind of blocks to replace each of the full set of 4 spring sets, removing them one at a time, will make it a lot easier.

Experiment with not putting them under the existing footers

I had 4 Machina Dynamica springs under everything prior to buying the Nobs. Well, I started pulling springs out late yesterday with 3 springs/ 3 Nobs under the Oppo first (decent improvement). Today I got busy starting with my LSA Voyager GaN 350 amp (OMG!), then my Audio Alchemy DDP-1 + PS 5 (here I only used 2 each X 3). This leaves my Core Power 1800 PLC, which currently has 4 Machina Dynamica springs.

 

I am totally amazed. I now have authoritative bass- mid bass, which gives the music more drive, putting a big smile on my face. CD is Lyle Lovett The Road to Ensenada. One of my torture test CDs is Jennifer Nettles Playing With Fire. It's on as I write this. Where many of the songs sounded thin, so far it sounds natural, like she's in the room .

 

There are a couple LSA Voyager threads, and a few guys mentioned they found it slight of bass: SURPRISE.

 

So thanks for this thread!!!!  I had them under all my kit, but never thought to experiment and pull springs out.

Nice. I have an aftermarket Furutech IEC hard wired with pure silver to the power supply and a silver jumper bypassing the 110/220 switch. The LPM has a good size toroid. I have 2 springs centered under it, a single spring directly under the CD tray and 2 springs near the back output side

Having removed lots of springs from the Nobs, under the various components, while the music was clearer, I lost the grounded aspect/weight. 2 things left speakers (a 2 man job) and my Core Power 1800 PLC, which is at the bottom of my vertical rack. I've been waiting for help, but last night listening to Blues Brothers, while the clarity was amazing, but overall the weight/soul of the music was missing. This is a very poorly lit room, and access to the back of the rack is difficult in daylight with all the cables, BUT, I decided to replace the 2 Machina Dynamica HD springs in the front with Nobs (fully sprung): WOW. The missing weight magically returned, SHOCKINGLY SO. Today's task is to maneuver behind the rack and insert 2 more

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
