However there seems to be a problem if a "dirty" component (like a wall wart or indeed a Devialet) is introduced into the board/conditioner. There is substantial cross contamination across all the sockets on the board/conditioner.

Dedicated runs from the CU (consumer unit i.e. the mains box supplying the dwelling) for each critical dirty component seem (from earlier mains power related threads) to go a long way to isolate components.

But is there still some contamination happening across dedicated runs ? After-all can't one's power be contaminated by the activities of our neighbours, local factories, etc.
And a dedicated run from the CU is still supplying "mains quality" power.
It seems that there are no definitive answers, just the many and varied anecdotal accounts of people's experiences with conditioners, regenerators, isolation transformers, dedicated runs, etc.
As I have mentioned somewhere before I use old and cheap, but for my taste the best power line conditioner, PS Audio - Noise Harvester. For my sound taste it is much better than this new Firewall. The main advantage is that it is plugged in PARALLEL not in series with Devialet or any other user component and it is blinking according to the line pollution, so it has visible effect to see the amount of line pollution. When I have removed PEM from Devialet power input I got better results than SAM and I also noticed that pollution is much more decreased. I have two dedicated power lines , one for analog and one for digital and only two harvesters, one in each line. Until now nothing bettered them.
