PowerBlack C19 H.C.

MK Toughplug to Schurter C19 'High Current' connector, with ferrite core

On the PowerBlack C19 cable, we use an MK Toughplug with ultrasonically cleaned and hand-polished brass pins and a C19 'High Current' connector. The C19 connector has high-quality brass contacts that are well sprung, which ensures that a good positive connection is made with the C19 inlet even after many insertion and removal cycles, reducing contact resistance. We can fit a silver-plated C19 connector to special order if desired.

Customer Testimonials.

I was the ultimate power cable sceptic when I bought your cable. I honestly thought it would do nothing at all and any perceived change in sound would just be a placebo effect. I could not have been more wrong. In fact I have seen far less dramatic changes from swapping out interconnects and tubes! The top end is smoother, the midrange now has even less grain and honkiness than it had before (and it was already pretty good in those respects), plus there is a "blacker" background than before. I am now hearing new, subtle details in recordings I thought I knew well for years. Amazing. My advice to anyone who has not bought one of these is to buy one first before purchasing any interconnect, speaker cable or tube upgrades. The change in sound from these power cables is so significant that it overwhelms the effects of any other "standard" accessory upgrade I have ever made.

I received the PowerBlack IEC cable yesterday and have had time to listen to it in my system - a reasonably high end one using Martin Logan Electrostatics and Electrocompaniet amplification. Very impressive - easily as good as the Russ Andrews and Isotek cables I own at less than a third of the cost.

Just to let you know that 4 of my friends were at my place and that I

asked them to view my TV as I tried 3 different cables 1...original

tv cable  2.....Russ Andrews Powerkord (not the Wattgate) 3....your PowerBlack IEC cable. The verdict was that yours was the preferred cable, the colour improvements are noticeable especially the red, blue and green. It was so good overall that they thought they were watching HD when in fact it was the freeview on the TV only!

Further Information
Every PowerBlack cable has a double shield arrangement of a dense tinned copper braid and a dielectric layer in order to give excellent electrical shielding characteristics, and comes fitted with a ferrite core as standard in order to suppress any high-frequency interference that is already present in your mains supply. These ferrites are an extremely effective upgrade, and are also available for purchase separately in our DIY Parts section, along with our silver-plated Blue IEC connector.
PowerBlack C19 cables are available in any length, with a wide choice of mains plugs. We fit an MK Toughplug with ultrasonically cleaned and hand-polished brass pins as standard, but can also fit mains plugs for Europe (Schuko type), Australia and the US, as well as male IEC connectors if you need an IEC-IEC cable. In addition, we hold several silver-plated versions of these plug types in stock, so please ask if you have a specific request.
