I found an electrical certificate I had done in around 2004 and the electrician must have been blind, drunk or bribed. We first rewired our house in 1997, the electrician was a Kurdish chef and I hope his food was better. The IEE regulations have been upgraded three times since then and a recent building job forced us to do a complete rewire, to make the house legal and less of a death trap. Had wonderful electricians, the entire system was replaced - every light, socket and just about every cable. We had a new 3-phase supply installed from the street and the audio is powered from a phase that has little if any other use, and is on an RCD with the car charger that gets used once a week. Dedicated feeds were installed to the audio system and the modem.
Whether this has improved the sound quality is difficult to say as the building works took 6 months. At least it’s reassuring to know it’s one thing ticked off the list never to be thought about again.
