I’ve reached the point where I’ll gradually upgrade my power cables.
But what should I start with: Individual power cables to my amps and turntable, or a central power strip?
Or do I have to get both to hear any difference?
I rented an office for a few years that had one circuit for the entire room. Everything was on that breaker, lighting, power outlets AND the air conditioner. It doesn’t sound as bad as the OP’s situation, but it was definitely compromised. My solution was to get a APS UPS (do they still make them?) and plugged all my sensitive electronics (computer, server, etc.) into the conditioned outlets. It gave me readouts of voltage fluctuations and interruptions. It saved my butt on more than a few occasions. Now I’m not sure if this would be a good solution for HiFi, but from what Mads describes it might be worth a consideration.
