@agisthos agreed. Don’t use hospital grade plugs or outlets. Unless your system or you are on life support.
@secretguy wasting money is a relative term. In example, if you own a low-fi or lower tier mid-fi system, you have paid very little or no attention to room acoustics, and/or your ability to hear and identify differences between components and cables isn’t yet developed, you may be wasting money if you’re buying cables, footers, outlets, vibration control devices, etc.
But, for some of us here a finishing touch such as a high quality outlet and the improvement it brings in represents one of the best values in this hobby. You’re just not there yet. And that’s fine.
