Many thx for the reply.
I got a used 4ms RCD with the expander. Unfortunately the expansion was a DYI and the soldering points are very fragile. A couple have broke off so I need to resolder. Looking forward to see the effect of the 4ms. I was thinking of getting a PNW but for just random clock it seems the Turning Machine will work great. Any thoughts? Again, I have zero experience with this ;) ......
