Thank you Joe. I am well used to waiting times with Lukasz, we just have to not think about it. Of course starting/participating in a forum on the subject can not help, but its so much fun. ...The amps should be made within a month so I will be happy if I actually receive them by Christmas. 
On your recommendation I will try Burmester 948 if my 211's hum, before I send them back. I think someone dropped a technical term as to why Lukasz has dealt with the transformer hum issue.
I seem to have taken a different route. First I have inserted a copper bar in the fuse of my ring main plug [illegal] and left the job of safety to the modern consumer unit trip and from then on I use Schuko plugs in the back of my SILK. Having tried all types of plugs from £50 to £250 and I find medium priced Gold plugs work best regarding the end flavour, I bought a length of monocrystal Oyaide 2.0 and make them op myself with 'Gucci' parts.
It is a process of painting the sound of the system and anyone can wire a plug, no? Rhodium seem to dry my system up and gold are more juicy with a silver IEC to the back of Silk to spice it up. I do not notice any benefit with the SILK flip function except for the deletion of sound from other appliances on the ring, but the switches have been an added convenience for turning on particular items. I do not believe that there has been an effect on the level of noise emitted by the Transformers. I do like symmetry and using a common hub and common length power cords appeals to me. It certainly does not make the sound worse and it is tunable.
I wondering what Lukasz' opinion is, does he use any other power conditioner other than the SILK, does he tune the instruments he sells us with/behind a power conditioner's signature? I will try to remember to ask his opinion. I think he may have made his statement about current with the SILK. Of course he is progressing at break neck speed so things might change in an instant.
