I think the main reason is the subtle differences in build between Nick's hand built and the Wand Co manufacture , essentially on the copper cage and the head and arms , Nick's is built out of four recessed plate's mounted on two machined copper rings , The WandCo's is die cast solid then copper-plated. Similarly the head and arms of Nick's are CNC'd machined out of a solid bar of aluminium , the WandCo is two diecast pieces, ( half head & two arms) bolted together so when each is assembled , there are slight varying detailed differences between them. In doing a conversion, one is trying to get the one (WandCo) looking like the other (Nick's) ., and in general you can get 95% accurate . It will take construction of another half dozen separate molds , hot metal casting of all the parts, and copper electroplating the rest to get to 99% and that's the best you can expect from the WandCo sonic that's not anybodies fault , it's just the way it was manufactured. This is going to be my next attempt , I've built the basic , I've built the enhanced and upgraded the stand, so all that's left is to try and remake the copper cage and the head and arms just like Nick's which should get me to 99%
