I know some of his products are met with derision on this forum but i have used a Russ Andrews silencer block with megaclamp for many years now. I originally purchase it when i had an Arcam FMJ setup but no use on my present Supernait /HDX plus FMJ tuner system. The compenent quality is high and can be customised to your exact needs, as the lead comes seperately and you have option of cable/connector quality and length. The block can also be screwed to the wall if wanted to raise the spaghetti of the floor. QED also do a cheaper power block without the fancy filtering that seems to review well, some plug a Russ Andrews mains silencers or clarifier into one of these. Of course all depends on the quality of your mains supply as to whether the filtering options make any difference.
