    I have a Cat6 backbone and patch leads already.

    The cable you linked to has shielding, and if it's not connected to ground the shielding is likely to act as an aerial. Using shielded cabling without properly earthing the installation can cause more problems than it cures, which is why there's no shielded data cabling here.
    If I lived near an electrified railway line I'd probably go to the trouble of properly installing shielded network cabling. Them 'lectric choo choos create huge amounts of RF noise, and the overhead HT cable has a permanent field around it too.

    Looking great.

    The cable looks decent too!

    I want to do something with my HDD psu eventually... to get rid of the cacky switching ones would be of a benefit IMO.

    I would also like to possibly upgrade from my SBooster BOBW linear supply... or maybe have it upgraded? Not sure if it's worth it though.

    I've found the SBooster filters to be very beneficial to sound quality on my network switches.
    The switch from Cat5e to Cat6 patch leads was subtle, but repeatable - the buffer on my Squeezebox Touch is big enough to permit switching of patch leads while the thing is playing. There's a short delay of 15 seconds or so, and a small change in sound quality. I ended up leaving the Cat6 patch leads in permanently.
    Putting the SBooster filter onto the power cable of the switch my Squeezebox is connected to was a WTF moment - it is a very noticeable step forward in sound quality.

    I was impressed that you managed to customise the fuse "MARCO".

    Yes, I like my copper!

    The wire itself will simply be some good quality stuff Duncan had bought a while ago, on a reel, from RS. No serious skimping on any aspect of the design of this PSU. All are simply sensible choices, free from any 'foo'...

    Dunno about your PSU SBooster, but I'll let you know what I think about the PSU Dunc's built. Just brought it home now, and yes both it and the mains lead look fab! Full report later

This is the supreme test. It is the glory of Lincoln that, having almost absolute power, he never abused it, except on the side of mercy".

    “You see these dictators on their pedestals, surrounded by the bayonets of their soldiers and the truncheons of their police ... yet in their hearts there is unspoken fear. They are afraid of words and thoughts: words spoken abroad, thoughts stirring at home -- all the more powerful because forbidden -- terrify them. A little mouse of thought appears in the room, and even the mightiest potentates are thrown into panic.”
