The above have been on ebay for a bit and I've been curious. I run a set of Townshend Seismic Pods (the heavy ones, so retailing at £119 each, x 4 is the best part of £500) which made a surprisingly big difference to the performance of my Thorens TD124. The Nobsound ones of course are considerably cheaper, only £29 a set, now shipped from within the UK (until relatively recently they were only available from the Far East).

Anyway they duly arrived just a couple of days after ordering, and I have to say opening the box, I was quite impressed. Nice manufacturing quality and it took no time at all - 10 minutes tops - to stick the rubber patches on the outsides, fit the springs and make the feet up as four cool looking spring sandwiches.

Out of the box with all springs fitted, they are very stiff indeed, supposedly rated for 32kg the set but I would say probably can be used quite a bit higher. I removed the middle spring from each and tried them under the TT plinth which is about 30kg all up with the solid wood plinth and Schopper platter. Immediate impression was that the bounce frequency was far too high compared to the Townshend Pods' slowly-moving single spring based assembly, which is also free to move in all dimensions not just up and down. I tried various combinations of springs, reducing the number in use from 7 down to 4 (practical minimum for stability), but there was a notable decline in performance in every configuration compared to the Townshend Pods. For turntables at least, these are not Townshend killers.

However I think they are mainly intended for speakers for that that purpose they could well be pretty good. (Not with my very heavy Tannoys though).

In the end I used them with four springs in place under my DAC (AN kit recently upgraded again and re-cased - with its very heavily upgraded PSU it is now comparable to in size and weight to and indeed in execution to the top end Lampizator DACs, and as heavy as a hefty valve amp, but just had rubber feet). I thought I detected a slight improvement so I've left them there, where they actually look pretty nice.

Upshot - curiosity satisfied but the Townshends have it for sure in a critical application like a turntable. Might be of interest for source components if they also produced say a smaller set with less stiff springs.
