I notice that Maplin have started selling some "audiophile" power cables:
That one (L85AZ) looks very similar to the Isotek Premium for half the price. (I had a couple of Isotek Premium cables but they got lost when I moved house, I currently have a Chord SuperScreen on the AV receiver) Or there's this one:
Looks similar but with the addition of a ferrite filter and Wattgate style IEC connector.
Anyone tried either of these out?
