Hi Big Air, as its a new installation it has to be installed by a Domestic Part P installer. Cost was £125 inclusive.
Installation is fairly simple TBH. 6mm twin and earth cable + 32A MCB. Could have saved a bit of money and connected the socket myself and run the cable, then you would only need the Leckie to wire into the consumer unit.
Had some other cable runs moved in the cellar and tidied up at the same time so was happy to give the job to the Leckie.
He tested the cct and my Z(earth value) for the house as well as testing the downstairs ring cct. All certified sothats good.
Initial thoughts, bit early because my kit need to warm up, but there seems to be a greater range to the dynamics,much more drive in the music noise floor is also non existant. Will post more when kit warmed up properly.
