I lived in London. Had new basement built and new mains so had the chance to sheath and earth it to eradicate RFI. Next, added a fuse box before the main house fuse box (important so reduces house interference). Used a Russ Andrews twin outlet supplying 20 and 30 amps to dedicated sockets for hi fi and home theatre (also steel sheathed and earthed). I even hard wired the Isol8 Qube2 from the 30amp which only powered the amp (MF Kw500). The 20 amp one fed an Isol8 Substation did everything else, flat screen, CD, DAC etc. The detail and sound stage was tremendous.
I have since moved to a rented house running it all on the 13amp ring main...oh dear! So best do the above; if you have the chance!
