My setup

PulseEffects is just awesome.

Add a lowpass filter to remove the frequencies that you can't hear and the frequencies that your audio speaker can't reproduce. This helps to avoid isochronic waves from malicious programs and malicious websites.

Trust your guts because having confidence is important for your health. Exercising outside is also good for your body. Touching grass and the ground is good for discharging electrostatic energy from your body.

For feeling even better, I improve my music audio quality by using USB-powered speakers; silencing the coolers in my bedroom; and making sure to use my computer and phone are on batteries because the power plugs on the wall may have incorrect or unstable voltage.
