Dedicated mains supply unexpected result

I have a dedicated consumer unit supplying my Hifi as I know a lot of audio enthusiasts have. It was installed a couple of years ago and has rendered excellent sound quality.

l recently had my house electrics checked out and the electrician said I should install a heavier cable from the house mains inlet. It was rated at 70 amps and it should be 25mm sq, 100 amps. The copper cable in both cases is the standard UK domestic quality.

The replacement work has been carried out, however the sound quality has deteriorated, less powerful bass and a shrillness added to higher frequencies. Neither of these issues existed with the original supply cable. Nothing else has been changed in the system.

Anyone experienced this phenomenon?

Good to hear! It took my system couple of weeks to settle after the dedicated circuit was run. Cable break in and ears/brain getting used to new sound.

It is not your imagination. My system sounded bolder and more pronounced, after I ran a dedicated 20 amp CCT

Aluminum is for cans! Copper is for electrical wire and pennies.

Not so, they are using aluminum cables for distribution lines and connections from the street to the houses, at least where I live in BC. And there isn’t much copper in pennies these days, in the US anyway, we don't even have them in Canada.
