The Nobsound springs arrived yesterday and I put them under my Audio Note Cobra. This amp has been sitting on an Ethan Allen wooden cabinet, beautiful, but not an audiophile accessory. The change is pretty dramatic- more dimension, better focus, just more of a "right" spacious feel to things. I’ll do some blind tests over the next few days if the family is up for it. I should be getting the Oreas today but don’t know if we will have power back in our region from the storm today.
May I ask if there’s any update on the Nobsound springs vs Isoacoustics Oreas on the Audio Note Cobra? Did you use all 4 Nobsound units on the Cobra and how many springs are installed on each Nobsound unit? I checked the weight of the Cobra and it’s 13.6 kg which isn’t too heavy.
