Over the last week or so I´ve been running a couple of mains cables bought from both Gordon (his Umbilical) and Mark Grant. Groundy summed up Gordon´s cable in his review and I also posted some results in a thread in the Amps Forum. Gordon´s lead is on my dvd player and Mark´s leads are on my CD player and Satellite Receiver. Both of Mark´s cables are Fig 8 type so no direct comparison to Gordon´s yet (Mark´s Wattgate arrived this morning so I´ll be testing that out today & tomorrow! ). Soon as I plugged the cable into the Satellite receiver, there was a difference, better definition and the image was less pixelly (need all the help I can get as we are way off the Astra Footprint for some channels like ITV, C4) with less noise in the picture. Audio is improved also, with better seperation & the cable makes the little details easier to pick out. Onto the CD player and the same thing, better seperation, more detail being revealed, bass was slightly tighter, but vocals are now clearer. Have to say Mark finishes his cables superbly, very well put together and professional looking. The Wattgate that dropped thru the post this morning (very well packed!) really does look the business. All in all, well impressed and can quite happily eat my hat as I was a bit sceptical about the claimed differences that mains cables make.
